Default AW4 probs

90 cherokee, 4.0 204k miles. When starting from stop it won't start in 1st when selector is in D. If I manually pull the shifter to 1st it will start in 1st. Then when I get to highway speeds it won't shift into OD. Just started doing this. Anyone got an opinion?? Thanks

I'd see if I can find any blown fuses labelled something like "TCU"

Coupla things.

First, click on the pink link in my signature and do #10. Photos are there for ya.

Secondly, look up under the passenger side dash for the TCU fuse. Inline flat fuse in a yellow connector/loom. Check it and clean the socket. Photo below for ya.

Thirdly, since you own a Renix Jeep, take the time to do #1, #3, and #5 at a bare minimum.
