Question about Isuzu Hombre

11 Answers

My son purchased a Isuzu Hombre (Chevy S-10)with a bad automatic transmission. He purchased it from a friend who bought it from a glass company who sold it because the transmission was bad. Friend replaced transmission and drove it 300 miles and the transmission started slipping very badly. My son bought it knowing the transmission was bad, pulled the old transmission out and exchanged it for a rebuilt tranmission. He drove it 75 miles and the tranmission startedt o slip significantly and got quite hot. The guy who rebuilt the transmission says the motor mounts are bad and that caused the motor to shift to the rear and caused reduced clearance between the transmission and the driveshaft leading to problems. I suspect there is something wrong somewhere causing the transmission to fail so quickly. Any insights and help would be greatly appreciated. He is a college student with limited funds. Thank you in advance.

    Trasmission cooler was connected and was working. Torque converter was replaced. Cooling lines flushed, not sure. It does not seem likely that cooling lines not being flushed wold cause the transmission to go bad in 75 miles. That seems like a very quick failure.

It does not seem likely that cooling lines not being flushed would cause the transmission to go bad in 75 miles. That seems like a very quick failure. I suspect that there is something else causing the quick failure of a just rebuilt transmission.

  • donaldflguy Sep 06, 2009

    I understand the principle of operation of an automatic transmission. The torque converter was replaced with a new converter. Given this is the third transmission failure with one at 100K, second at 300 miles and the third at 75 miles there seems to be a bigger issue than fluid level.

  • donaldflguy Sep 06, 2009

    I am not sure what the impact on the transmission is if the motor mounts are bad.
    Also I am still wondering why the first transmission went 100K, the second transmission when 300 miles (prior owner)
    the third, transmission went 75 miles before it started slipping severely.

  • donaldflguy Sep 07, 2009

    So I have heard that the cooler needs to be hooked up to the transmission, working properly and the fluid level needs to be proper. Not very helpful for the diagnosis. Also I have heard that the truck may need an external transmission cooler, good idea but the truck went 110K miles without one so that was not helpful in solving the cause of the transmission failure. Then it was suggested that the cooler lines needed to be flushed prior to installing the rebuilt transmission. No one has said that if the lines were not flushed, that this would cause the transmission to fail in 75 miles. (I find that hard to believe.) I am told that heat and dirt will kill a transmission (interesting information but does not help with the diagnosis of the problem.) I am told if the motor mounts are bad, the transmission will have more stress on it. Interesting information but no one has said conclusively that this would cause the transmission to fail in 75 miles or 300 miles. No mention of what component(s) in the transmission would fail due to stress on the transmission case as a result of potentially bad motor mounts.

    No mention of running a diagnostic on the computer for any transmission error codes. Would the error codes help diagnose the problem?
    Transmission went 110K on the Original equipment, 300 miles on the first rebuilt transmission and 75 miles on the second rebuilt transmission. I am looking for the explanation that first "A" happened which lead to "B", and then because "B" happened, that lead to "C" and once "C" happened the transmission failed. The logic needs to explain at least the last two failures with very low miles on the rebuild and perhaps also explain the first failed transmission at 110K initial failure.

  • donaldflguy Sep 07, 2009

    1998 Isuzu Hombre with 110K miles the 2.2 liter 4 cylinder engine with a/c and otherwise a very basic truck.



    Please read the entire description of the question and answers before you respond with a diagnosis.

  • donaldflguy Sep 07, 2009

    If the motor mounts are bad, a new transmission will not solve the problem. If the transmision cooler is not working properly, a new transmission will not solve the problem. Get a new transmission is not a diagnosis and would not solve the problem. Apparently this last "expert" did not read even half of the described problem.

  • donaldflguy Sep 07, 2009

    Still looking for a diagnosis that clearly identifies the problem and clearly explains why the first transmission went 110K miles, the second transmision lasted 300 miles and the thrid tansmision survived 75 miles. The one who answers this question will get my acceptance.

  • donaldflguy Sep 07, 2009

    I have not checked the motor mounts yet. If the motor mounts are bad, what is the cause of failure?

    In other words, what it the problem that causes the tranmission to slip severely in 75 miles?

  • donaldflguy Sep 07, 2009

    Can you explain why this would be the cause?



    I am waiting for a good diagnosis before I start replacing parts. The questions and answers have been many. One "expert" suggested that we needed an external cooler, one person suggested we needed a new torque converter. Another wanted to know if we flushed the cooler lines. Another wanted to know what fluid was used.

    I was expecting answers with some rationale behind it and not just "replace with a new transmission" or "replace the motor monuts" or "add an external transmission cooler"

  • donaldflguy Sep 07, 2009

    No reason given for the need for motor mounts and no rationale given for why it will solve the problem. Kindly read the entire description before providing an answer.

  • donaldflguy Sep 07, 2009

    What does the twisting motion do to the transmission? In other words, what damages the transmission to the point it slips severevely in 75 miles after a rebuild?

  • donaldflguy Sep 08, 2009

    I am looking for a specific diagnosis before I suggest replacing the transmission again.....

    No mention of running a diagnostic on the computer for any transmission error codes. Would the error codes help diagnose the problem?

    Transmission went 110K on the Original equipment, 300 miles on the first rebuilt transmission and 75 miles on the second rebuilt transmission. I am looking for the explanation that first "A" happened which lead to "B", and then because "B" happened, that lead to "C" and once "C" happened the transmission failed. The logic needs to explain at least the last two failures with very low miles on the two different rebuilt transmisions

  • donaldflguy Sep 08, 2009

    what is it about the destruction of two transmissions in less than 400 miles leads you to believe the motor mounts are bad? Bad motor mounts, I agree can contribute to a transmission failure, but I find it hard to believe that bad motor mounts are the reason for 2 failed transmissions in 300 miles and then 75 miles. Please provide additional information as to why bad motor mounts will lead to transmission failure in 75 miles.

  • donaldflguy Sep 08, 2009

    I believe it was mercon fluid. Bad Motor mounts seem unlikely to cause a newly rebuilt transmission to fail in 75 miles.

  • donaldflguy Sep 08, 2009

    I agree that it is not likely the motor mounts, but given the second tranmission was rebuilt by a guy who gives a one year warranty, if he did not know what he was doing, he would not be able to offer a one year warranty. However, it is possible it was the rebuild job. However, the previous transmision that went 300 miles before failure was rebuilt by someone else so it is not likely to be the rebuild job given it happened twice by two different transmissions. Given the history, I suspect the cooler stopped working or was plugged and that is why the glass company sold the truck with a bad automatic. Second owner installed a rebuild with new torque converter and drove it 300 miles but it may have been around town. Third owner and third transmission lasted 75 miles but 55 of those 75 miles were on the highway. So if the cooler was not working properly, that could explain the rapid deterioration of the third transmission. Actually if the cooler was plugged, it could explain why the glass company sold the truck in the first place and why the two subsequent rebuilt transmissions failed so quickly. What do you think?

  • donaldflguy Sep 08, 2009

    Not sure about vibration, I will ask my son. Your responses are the best practical answer I have seen yet. While asking me about the fluid level and other very basic questions, fluid being low does not destroy and just rebuilt transmision in 75 miles. I just wish the other "7 or 8 Experts" would have read all that I have written before they answer. I even had one "Expert" ask me if it was an automatic transmission, which if he had read the first line of my description he would have known that.

  • donaldflguy Sep 09, 2009

    Did you read any of the description before you replied?



    I am begining to think the "experts" have a short attention span or don't read the entire description.



    Does the oil in the gear box explain why the second rebuilt tranmission failed in 300 miles and the third rebuilt tranmission failed in 75 miles?

  • donaldflguy Sep 09, 2009

    Original owner sold truck with 110K miles due to bad automatic tranmission. Second owner replaced bad tranmission with a rebuilt transmission and a new torque converter. second transmssion lasted 300 miles. Third owner replaced the bad transmission with another rebuilt transmission and a new torque converter and this one lasted 75 miles. The answer I am looking for should explain why each tranmission failed and what needs to be done to crrect the problem.

    Obviously just replacing the transmission with another rebuilt and another torque converter will not solve the problem. Any "Experts on Automatics" want to give it there best trouble shooting and answer this question?

  • donaldflguy Sep 09, 2009

    Finally, an aswer where the description was read and the answer fits the description. Thank you.

    We will verify the cooler is working first before pulling the bad tranny out, then check the motor mounts with the tranny out. If either are bad they will be replaced, then replace the tranny with another rebuilt and new torque converter.

    I believe the tranny was rebuilt properly.

When you say slipping what exactly do you mean??? Just want to get a better idea whats going on. Most newer trannys are computer controlled and slippage is caused by worn parts, 75miles is a very short peroid of time for something like that to happen. Have you had the motor mounts verified by someone else. Can easily be checked by looking under the truck for shifting. If the mounts are bad to where the engine has moved you would notice the motor jump when put into gear or under hard acceleration or under load as the motor would twist as the mounts keep it from doing so. You can move the motor very easily by hand if it has broken loose from the mounts ($100 repair at a shop) or you can do it yourself for less then half. If the motor had shifted rear the driveshaft would not connect as it would be too tight (shaft doesn't bend) and your installer should have cought that at installation and made appropriate fixes. If the shaft was possibly pushed back further causing the angle the change (be more piveted) its possible to cause premature wear on the tranny/rear end due to binding. Your first failure would have been the center driveshaft bearing (supports the driveshaft about half way between the back of trans and rear wheels. This would get the most stress. Check this too as it wears there is excessive vibration while driving and could also be a cause for premature trans wear. The last thing would be just as simple as it sounds a bad rebuild!!!!! If it wasn't done correctly it will fail very quickly. Have you contacted your trans shop first??? If its under warranty you can have them check it for the cause. Depending on who did the rebuild they may not warranty it if they did not install it!!!

Ya, there's something wrong alright, and it's probably not the motor mounts! Sounds more like the guy who 'rebuilt' the transmission. Transmission rebuild is an art and a trade! Not just anybody can do it. It's one of those things that needs someone that does it all the time to do it right. I would recommend cutting your losses here and take the easiest way out you can put together. It's not going to get any better....

    This vehicle really has an issue for sure with the transmission. There is something very wrong here. It could be some alignment thing. I've worked with motor driven machinery for 30 years and there is one thing I've learned for sure; shaft alignment is critical. If the shaft from the transmission is out a few thousands, it's going to throw everything out all the way in. It puts stress on everything and causes excessive ware on the bearings. Has anyone ever checked the drive line yet for balance and trueness? If that drivel line is slightly bent....
    Does it vibrate going down the road?

    I had a simmaler issue , and it turned out to be the radiator ,which had been replaced with a new one just prior to the transmission going out the first time.
    we went thru 3 rebuilds and new torque converters before it was realised that the radiators trans oil cooler lines were clogged with debrise discharged from the overheated transmissions and caused a blockage which restricted the flow enough to cause a brand new rebuilt 4L60E to burn up in 60 miles.

Slippage is a very troubling and annoying problem that can be caused by a variety of factors. Transmission slippage negatively impacts vehicle operation and can lead to transmission failure if not properly addressed. What follows is a brief list of the most common causes of transmission slippage.

    Low Transmission Fluid Levels
  1. A low automatic transmission fluid level reduces the hydraulic pressure load within an automatic transmission, a condition that can cause transmission gear slippage and dysfunctional transmission operation.
  2. Worn Transmission Bands
  3. Automatic transmission bands, which are rubberized bands linking together the gears within an automatic transmission, are vital to transmission gear shifting and operation. Worn or broken transmission bands can disrupt automatic transmission gear function and allow gears to slip out of place.
  4. Worn Transmission Gears
  5. For proper automatic transmission function, the gear sets that comprise the main functional center of the automatic transmission have to be working properly. Worn or frayed transmission gears do not link together properly and can slip out place.
  6. Faulty Torque Converter
  7. An automatic transmission torque converter, which is a high-powered hydraulic pump responsible for pressurizing automatic transmission fluid, can cause a transmission to slip if it loses its ability to generate enough force to properly pressurize transmission fluid.
  8. Transmission Vacuum Hose Leaks
  9. Vacuum pressure, supplied directly from a vehicle's running engine, plays a large part in automatic transmission function. Vacuum pressure helps to keep automatic transmission fluid moving and under set pressure guidelines; any disruption of vacuum pressure to an automatic transmission can cause a variety of transmission problems, including transmission gear slippage.

Yes. motor mounts are there to to hold engine in place as well as to keep the engine aligned properly with the rest of the drive train. When they are bad, the engine is putting extra stress on the transmission causing it fail early, not to mention the engine will wear down the rings and push rods from heavy vibration.
This is kind of explaining the level becomes more severe from failure at 100K, then 300, then 75 miles.
The motor mounts is not expensive to replace. Let the last guy change the motor mount and rebuild the transmission again, so there is no more excuse.

I would get a second opinion about the motor mounts, to be sure the tranny guy is not simply trying to evade responsibility for faulty work.

What does "motor mounts are bad" mean? Are they broken? In any event, replacing the motor mounts is fairly simple. If your son can get a friend to help him do it, the expense would be minimal. If the motor mounts are the problem, replace them, and have the tranny fixed, or buy a rebuilt

Well in an automatic gear box ,you have a torque converter ,have you change the torque converter?The torque converter can not be repaired so you have to buy a second hand one put it then the problem is here not in the gear box,also be sure the level of oil in the gear box is at its full level.It is the torque converter which transmit the force to the gear box,if the torque converter slip it will not have power to the gear box ,so drive ,hope that clear your mind and help you Mr.

Is the transmission hooked up to a transmission cooler?
Is the transmission cooler working?
Do you need to add an extra cooler to the transmission?
Were the cooler lines flushed before attaching to the new transmission?
Was the torque converter changed or replaced with the transmission?

Contaminated fluid and heat kill transmissions.

In 1996, Isuzu replaced its Pick Up with a version of the Louisiana-built Chevrolet S-10, the Isuzu Hombre, based on the Brazilian market S-10
so google the vortec 4300

My 1998 Isuzu Hombre will not stay in overdrive I have changed fluid @ & filter also seams like vacuum pressure is high like my breaks r engaged


breaks = brakes?
the brakes use vacuum but never changes it.
so...... if it does, the booster diaphram is cracked.
OD, can be just a bad OD. switch or more complex.
did you scan the TCM yet if it has one?

why state vacuum high, then not state the values seen?
you connect the gauge, and it reads what? 19inches HG at hot idle is common.
or 0.64 bar (outside usa you use BAR) as you said pressure word for vacuum and is ok in pure science that word) but make me think yoiu are not in USA? or Canada maybe....????

i bet vacuum is just ok.
the issues are with the transmission and its controls.
post is older, are you still having issues.
do say and we can link you up to FSM information on 0D.
the book covers this.... ever see a real FSM before.
the real factory service manual,, (buy one, and win?)
or if in USA , alldata.com is #1 online version of same.....
there are others, but nobody ever posts the country
making most answers wrong, including MINE.

i only have questions, after all im blind cant see car nor open hood.
so... what engine is there, transmissions match engines. so....

omg its really a chebby. Chevy
The pickup was also sold by Isuzu as the Hombre from 1996 through 2000, but only in North America
its not ISUZU at all.
you should know this and post to chevy, S10
2.2 liter or 4.3L engine
my guess is 4.3L with Brazil front sheet metal.

there are 12 control lines from the PCM puter,
and the transmission,
to find out why the OD fails
we first check all fuse..... (on all electric fails we do that)
then check levels hot, by the BOOK.
then scan the PCM for transmission errors, P07xx ? codes>

i look at the alldata. com at the Hombre 98 , pcm page.
schematics.
od .
we make sure no errors from PCM
then check the switch, to PCM for OD active.
if the input is ok.
then we check the solenoid voltages in OD.
if correct then the problem is ok, outside trans, and not inside.

This trans is electronically shifted.
and uses a computer (TCM)
so inputs must be right to TCM
an outputs correct. if not , never blame the tranny first.
