99 cherokee.
Strickly my welling mobile. I have always wheeled it in 4wd low gear and with the tranmission selected in the 1/2 gear with the shifter.
Lately what it has been doing is when i am driving it will red line first gear and then shift into second gear and then 2 seconds later it will down shift back into first gear, which then causes it to be way into red line. It shouldnt be down shifting back into first, it should still be in second. Can anyone help or has anyone ran into this problem before and what should i do to fix it
Its super annoying

Can you explain more??? It worked fine and then suddenly it started doing it.

Does it shift OK otherwise? If not, check the 10 amp fuse for the trans controller in the power distribution box under the hood.

When in 1-2 it should stay in 1st until 4500rpms or so, and then shift into 2nd. If the TCU is unplugged or the fuse blown, it will pressure shift rather than by electronic control.

chadtheman

yes otherwise it shifts ok. I will check into the fuse. I didnt check that yet for sure.

Any other ideas, like why would it do that

chadtheman

fuse is good, any other ideas??

Try 3 when in 4 Low and see how it works.

There is at least one thread on how to keep the AW4 locked in 1st or 2nd by adding switches.

chadtheman

yes still works fine, in third and i have been trying to find that thread!!! no luck yet!!

I liked the second article.. Too bad i have a 99 and they said it wont work.

I guess ill keep looking, not really sure yet if i want to invent another 150 just into the control unit.

I only use this cherokee for offroading and who knows how long its going to last.
