Question about 1999 Isuzu Rodeo

1 Answer


Check the differential and trans case. Can replace those for a few hundred. USED of course so watch the miles on it and the color of fluids and metal build up on the magnet in the differential. Check throttle position sensor and clean range sensor. Keep surfing the net, there are numerous sites with people all experiencing this. You can find some of these other possible issues causing your hard shift. I dont think its your trans at all.

Drops out of OD.

Fluid Change has nothing at all to do with a fix
Nothing at all & on a worn trans can cause slipping
In your case I assume a shop gave it a try
The hard shifts tell you the valve body needs cleaning
I would first look at all body data related to the trans,whatever
your truck has TCM Module whatever
I would check all bulletins at a repair shop in their data base
I would have a mechanic ride with you to look at the trans
with the scan tool on it & watch the speed sensor & any
external sensors you may have for correct data
No also check the brake switch
Does it go into Lock-up in most gears (brake sw )

Rideing down the road 50 mph at times the trans will act like it jumps out of gear at the same time the rpm goes up. just started it after driving 250 miles with no problem. this is a rebuilt trans in 2008...

Check the warranty. Hate to say it, but I know you pay top dollar to have a transmission rebuilt, 3,000 to 4,000 dollars at some places. This doesn't mean that they replaced or put in all new parts, Which at that price I think they should. solenoid packages can run $50.00 to a few hundred dollars and you get charged thousands., no hard parts replaced. And vice versa. Sounds like a solennoid piston, which has orings, is beginning to fail.If were mine the first thing I would do is put a transmission additive in it, Tranx, lucas. These work on the seals/orings. I have used Tranx and it has lasted years. If after time this doesn't solve your problem, have a diagnostic check on the solenoid package and replace if necessary. These are not hard to replace in most transmissions.

Dodge dakota 2005 automatic transmission, when starting from a stop or low speed sounds as if it is low on fluid rpms high started doing this on tollway when pulling out from the toll both ????seems to...

Manually shift thru all gears up & down the scale. Try adding Motorcraft Additive Friction Modifier, available from Ford parts dept. This REALLY STINKS!!! Don't get any on you. Pour into trans fluid. Drive a few miles shifting manually thruthe gears, then do a normal start stop drive several times. This will luburcate trans, normally used for differential but has worked in automatic transmissions of all makes for years. Otherwise mechanical problem for transmission repair facility.

How do i fix the gearshift on a manual transmission

If the gear shift problem you refer to is that it's hard to shift into gear while stopped, the clutch is not disengaging far enough. If the clutch is hydrolic, check the fluid level. You may need to bleed it. If cable, there may be an adjustment you can do at the trans end. Or, another reason trans is hard to shift, the trans has come loose and is binding on the pilot bearing. If you have enough miles, the pilot bearing may be bad. Of course, the trans could be worn out as well.

2005 ford five hundred limited 2wd 6spd trans 139k miles. Recently replaced mounts thinking that would stop the trans from downshifting hard at stopping. But since the replacement the rpm will not go over...

What you might try is changing the Trans fluid and putting in a new Trans filter or cleaning the filter if it is not disposable. If this does not help before replacing parts on the Trans ask if your Model has a Software fix.

Many of the newer vehicles have computer programming to control the Trans behavior. Since changing the mounts made a difference, the old parts were obviously worn. Now you need to smooth out the shift points.

If you want to try 1 cheap part, get a TPS (throttle position sensor) which is on the Airhorn. Its function is to set fuel mix and timing advance and to communicate that to the Trans. If the Trans does not know how far the throttle is open, I can see it would not know when to shiift or downshift.

Transmossion problem on a1998 chevy ck1500 with a 4.3l vortek, 4l

only diagnostic procedures will find the exact cause. Unless you have the info and the tools to perform this your going to have to have a shop perform this for you.
Guessing only works if your always lucky when you go to Vegas.

Honda passport trans light flashing

Most likely you have a bad transmission pressure solenoid. You weren't too specific so here's what to look for: The engine light, the trans light and the shifiting, if when you drive on a level surface the suv seems to shift late and very rough...that is probably what it is. It's a few hundred to have fixed because they have to pull the casing off the trans and they'll want to replace the fluid and filter too. good luck.

94' jeep grand cherokee trans. delays in reverse

Hi ray_c_brown, This pause is determined by a time lag test, and you can check this yourself with a stop watch.Engagement time in "D" range should be a maximum of 1.2 seconds and the engagement time for reverse should be a maximum of 1.5 seconds. So with your vehicle warmed up and assuming curb idle speed is correct set the park brake,make sure ac is off (air cond) shift transfer case to 2H or if it is a NP249 transfer case leave in 4H,put your vehicle into neutral and set your stop watch shift to Drive and record time repeat this a couple of times and do the same with reverse,as you said the delay is with reverse so if it takes longer than 1.5 seconds here are a few things it could be:shift cable adjustment,low line pressure,worn direct clutch, first/reverse brake worn or a worn or damaged overdrive clutch.Hope this helps you good luck :)
