Chrysler Repair: transmission will not shift, solenoid pack, etax

Question
I have a 1995 sebring and the transmission will not shift out of 2nd gear. I had the transmission scanned and it comes up...2-4 pressure switch. I have changed the sylanoid pack,all 4 sensors on the trans,filter and fluid. I've aslo checked the wires for a break between the the pack and the trans. computer and that seems fine. I also changed the trans.computer and I seem to still have the same problem...One thing I have noticed is that for the first 5 mins of running in the morming it is fine till the engine warms up and then it will start to act up and if I stop and restart the car it will shift ok till I need to stop again...can you please help...Thanks

Hi Terry,
I have the '96 Cirrus/Stratus shop manual which has a section on the ETAX which is probably applicable to your Sebring. There are 2 codes that speak of the 2-4 pressure switch faiure and the 2-4 pressure switch circuit, respectively. The first is code 32 and the second is code 22. So it might be helpful to know which is the actual code number. The 32 is the less hopeful because it only has the possible causes of high/low trans fluid, solenoid pack problem and internal trans problem (which means some dismantling of the unit). You have covered the first two with no success. Also, it doesn't set a code until the trans is at the normal operating temp, which is how you describe the onset of the limp-in mode that is the result.
The 22 code offers a couple of more possibilities as causes:
short or open in the 2-4 circuit and a problem in the 40 way connector (cavities 9, 47, and 50), and a failure of the control module itself (internally). It does not require that the trans be warmed up before it could be set. For that reason the code 32 seems the more likely one for your situation, but you could inquire of the person who read the codes as to exactly which one it was.
So that is as much as I can offer to you. The best thing to do if you aren't intending to remove and dismantle the trans yourself would be to find a mechanic with lots of experience with the Chrysler ETAX and who might therefore have the finesse to decide if the trans has to be removed and whether the amount of work to effect the solution to the code might be less than a so-called 'rebuild'. I haven't done work on transmissions personally so would not hazard an opinion.
