Is there a way to lock the overdrive, either on or off?

its a 93 with an auto and a strait six, It has been acting up, its not mine but a friends, and will come in and out or not come in at all giving it a 4 speed basically.

It has a rebuild tranny because the torque converter locked up in 4th gear a while back rendering the tranny useless. and now it has this issue. we would like to be able to lock it in or lock it out if we could

 

This doesn't make sense to me. "It will come in and out or not come in at all...", but then you say "the torque converter locked up... rendering the tranny useless." Does the trans function but OD doesn't? Will it not idle in gear? Please explain further.

alright, the tranny was rebuilt DUE to the TC locking up. Since then it (about 1000 miles) it has started to have OD issues.

When driving around the city the green OD light on the dash will go on and off and the tranny will "overheat" according to the dash computer. On the freeway it will work then it will go out and just up about 1000 rpms and get horrible gas mileage then it will come back on and work then turn off and so on and so forth to where it finally stays off or stays on. But the computer does not show it over heating.

We have checked the fluid it is not burnt and still has a very nice color. There is no driving issues about the transmission other than the over drive. It shifts clean, it down shifts fine when stopping, it kicks down fine, just the overdrive goes nuts.

 

If its the AW4...check the OD solenoid behind the trans filter. Mine is having the same issue but im too lazy to replace it. You can get a set of new solenoids for less than $200 online. They are easy to replace but you have to drop the trans pan and filter.

 

If it's only been 1,000 miles since it was rebuilt I'd take it back to the person that rebuilt it and tell him to fix it. JMO

yeah... unfortunately due to this bad economy that shop no longer exists....

 

Stupid question sorry for the hijack but do only 4wds have overdrive? Does my 94 2wd have it if so how do you turn it on and off or is it always on?

 

your 92 should have it, from what i can remember the XJ has it and the button should be on the shift lever..... not 100% positive it should be a little button to en able it and dis able it

 

i have a 94 and no, no little button

 

That is why I took my ZJ to the dealer for a crate tranny with a 3/36 warranty.
