I have a 94 chevy 2500 that is stuck in 3rd gear, or wont shift correctly, shop says its an "ignition switch"


My truck had this issue, or one very similar. The 4L80E transmissions have a defect where transmission fluid can leak up into the big round electrical plug and short everything out. There are YouTube videos on how to clean out the plug and seal it so it doesn't happen again.

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.

Code Reader reads Shifter Solenoid Stuck or Off


The Shift solenoids are located in the transmission oil pan. I would recommend replacing both shift solenoids while you're in there. Also replace the filter and pan gasket. The shift solenoids are located towards the rear of the valvebody and will be identical to each other. They are held in place by a retaining clip which is easily removed with a small screwdriver or similar tool. Care must be taken as parts may fly out of the bore when the solenoids are removed. Hope this helps.

Has the 'Check Engine' light come on? I had this problem at 30,000 miles and the trouble codes set were transmission component slipping. Ultimately required replacement of the transmission.
