Aw4 30-40LE. Stopped shifting.
I decided to name my 89 Jeep Grumpy. Sure acts that way. Got 188050 miles. Transmission was shifting fine. Only once did I think I felt it slip going into OD. When I say overdrive, I mean the D has a circle around it. Is that common? There’s no button to manually turn OD on or off. When I shift down to 1-2, I feel it downshift. Any thoughts?

Sine it is an electric controlled transmission, I would start with this...

Now I have to figure out all the adjustments to make sure it’s shifting right. Grumpy wants to downshift when you let off the gas. And it seems to be idling a little too fast.

You must complete Tips 1,3,4,5 and 10 at www.cruiser54.com before anything else.
Then, adjust the TPS and throttle valve cable.

Ive found cleaning the butterfly on the throttle body helps too. If it can't shut all the way it will throw off the TPS and hence the shift points. Any mill with 100k or more will get the carbon circle around where the butterfly closes. MAF cleaner and toothbrush.
