    i dont know where to start because Im so frustrated right now with what i just learned through a simple diagnosis but was never done by AAMCO transmission, instead AAMCO wanted to do a $1,600. rebuild without even diagnosing my problem -a bad solenoid valve. I am a poor man with a '99 Suburban. I learned yesterday that this was all that was wrong with my trani through a simple diagnosis at an Auto Zone Store. All finally happened when my inspection guy said my Service Engine Soon light would probably not let it pass. Since i didnt $1500 to drop for a total rebuild at the time I held out till I could afford it. To think that my trani might have been repaired for hundreds less makes me sick to my stomach. Thank you AAMCO but the pen is mightier than the sword, people are gonna know what crooks you are. -M.O., Houston TX

SOURCE: Auto Transmission in 94 Chevy K1500 will not shift into 2nd gear

Hi, yes I just had the same problem and the clutch packs inside the transmission are slipping. I had to replace all the clutch packs as well as the bands. The parts for this job really aren't that expensive. you could get everything you need for less than 300 bucks. however labor is where they kill you. It's about a 10 hour job or maybe 12 depending on application. average shop rate 80 an hour you looking at 900 dollars labor plus parts. if your mechanically inclined and have tools you could take your time and do it yourself. you can buy a step by step DVD for your specific application. other wise I would call around to transmission shops. their is a slight chance it may also be your solenoid pack. the best way to confirm is to have a transmission line pressure test done. I hope this helps!

SOURCE: my 97 chevy blazer won't shift past 3rd gear

Drop the pan, odds are the shift solenoid is out, its located at the front of the trans on the driver side. I'm sure your check engine light is on that will comment about the timing/shift solenoid being bad. I had the same problem with mine. The solenoid had plastic coming out of the inside. To remove it you'll find a small C clip holding it in, just take a small screw driver and pull the clip out. The part cost me like $36 from my local dealership. And its a longer solenoid. I believe its the 3-2 downshift solenoid. I do have the part number if you need it.

Transmision starts out in 1st shifts to 2nd then third but will not shift into overdrive , but once it reaches 3rd gear ,it stays there when you come to a stop . after that it will only shift manually...


Sounds like your transmission is in limp mode. This is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.

The other from what you described, trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Thank you for using fixya and have your Safari scanned for the DTC codes that would indicate what issues your transmission is having to put you in to limp mode.

92 chevy s10 4x4 4.3L manual transmission no 3rd gear


Hi:

Your transmission has 3 shift rails...
1st - 2nd
3rd -4th
5th- Reverse

If your 3rd gear doesn't work , you have an internal transmission problem, such as a syncronizer, or similar fail... There is not much you can fix, without removeing the transmission.

What you need to check is the transmission release bearing because if there is a clearance on the release bearing you will encounter this problem and also check the transmission oil.
