He guys i have a 1992 jeep cherokee and it runs fine and drives great it is a automatic but I have to shift it from first through all of the gears up to drive if you try to pull out in drive the transmission is in drive not 1st and so on It has been like this a while any ideas on how to fix it?

If it won't shift automatically the electronics aren't working. Check for power to the TCU first- I believe your year has the inline fuseholder just above the passenger's knee area. 10A IIRC, wrapped up in the TCU harness.

I think it is the TCU also it has been like that a while is there any way to check to see if I am getting power I would like to know that's my problem before i dropped 50$ into a new one and that doesn't fix it

Check the fuse?

Is this the same thing as the transmission computer?

This is probably a dumb question but It doesnt hurt to ask a 5 speed TCU wouldnt work in my auto would it

cruiser54

Yes.

Correct. 5 speeds don't have TCUs.

I got a TCU ordered this morning should be here today or tomorrow. My local mechanic is ordering it for me but ill put it on. I looked yesterday and guess what there was no TCU in my jeep at all. The guy before me rigged it up somehow that their is a switch on my dash to put the jeep into second gear and then on into 3rd then drive. I asked him about it he said it was a common thing people have done but I can't find it any where do any of you have ideas? will i just be able to throw the TCU and a fuse in and hopefully fix it?
