No I have not. I guess I will start pricing one. Any chance someone could tell me where it is located or a picture of it? Or is there a write up on changing these things?

I was going to ask the same thing about the OD solenoid, but wasn't quick enough. I'm not sure which trans. you have but here's a link with some parts:

On my 42RE, drop the pan and it's right there, next to the govenor pressure/solenoid. Not hard, Haynes would be helpful

I had to pull the valve body to change my OD solenoid. Speaking from experience, if you can't get the vehicle at least two feet off the ground, get some help to put it back together. It takes at least three hands or a great deal of trial and error ingenuity. The park rod is a pain. I did mine with rear wheels on ground and jack stands under the front.

I will pick up a haynes today and do some research. I think I have a 42re but dont know for sure. How can I tell, I have a 97 ZJ 4.0 with AWD. full time, N, and LOW. I also looked at some parts from the link RLC gave me but I am guessing the only way to know if its two or three pin is to drop the pan.... again.....

Ok, so I am going to order the part on monday. Just to be sure, I need the overdrive ,lock up solenoid for the 42re?
Would this be the correct part?

If not could someone point me in the right direction?

Well got all the parts in today. About to drop the pan and put everything in. Does anyone know if the valve body has to be removed to change the wiring harness for the OD and TCC solenoid? I guess i will find out when I look but just want to be prepared for anything crazy. Will update with how the fix goes.

Well I got it all changed and now its throwing code 37. Im lost and have no more ideas. Anyone good with transmissions in kentucky near louisville interested in some pizza and beer and some cash. I just feel like giving up on this heap. The money pit of fluid and electronic parts is getting to deep

Was the battery disconnected while installing new parts? Can also try disconnecting battery and resetting PCM. How is it driving now?

I unhooked the battery while putting everything in. Now when I am driving it feels like its only got 2 and maybe 3rd gear. I feel like something with the overdrive and TCC solenoid is wrong.

Does anyone know if I can run the computer test with the key on off thing while the pan is down? Or is it only a stored code as in it wont tell me their is still and issue until I drive it again? Looking for a way to know that each solenoid is working.

Have you changed you transmission relay? Yes you can run the key test. No you cant check operation with pan off, it works off the pressure solenoid and speed sensors through the PCM.

Did you pull the VB and did you use a torque wrench to put it back on?

I have changed the relay with a known working one. I didnt mean check operation as in start it. Lets say the connection is off of the TCC solenoid and I hook it back up. Will the 37 code drop right then or will it have to be driven for the code to drop? Provided that was the issue.
