92 automatic. In drive it creeps forward, even if i floor it. In reverse it feels like i have full power but drive nothing happens?

Check fluid level? Check the linkage at the transmission make sure it's actually going into drive.
OR if you're handy with a welder, turn the driver seat around and drive it like that.

Yup, check the transmission fluid level. The vehicle needs to be on flat, level ground. Make sure the vehicle is warmed up, running & in park. Can you test the transmission solenoids? There are YouTube videos out there, describing how to do so. Otherwise, you might be better off, taking it to a transmission shop.

possibly trying to take off in high gear, due to solenoid or TCM issue ?

I am not familiar with the early models, and whether disconnecting the TCM fuse or harness, and moving the stick to low gear may be worth trying

boxburn

This was my thought, me being biased on the solenoid issue.

Try setting off in 1-2 then moving up to 3 then finally D. If it works normally then it could either be a solenoid issue or the TCM fuse.

Transmission fluid is good. Tested it and it took off in 1/2, and works in 3rd. Went to drive and it feels like its still in 3rd.

awg

sounds like a solenoid..maybe TCM issue, could be wiring in between

test solenoid resistance, and replace if needed, check all wiring and harness connectors, replace TCM, if needed

Morat

Yep, sounds exactly like mine before I changed the solenoids. It would change up but not down. Luckily, the ebay solenoids are cheap and have been perfect for at least 18 months so far.

I had that problem once years ago, it was a clogged filter and burnt fluid

Are you sure the Throttle Valve cable is adjusted properly. This can burn up an automatic transmission quickly. I assume you have the 700R4 in your jeep? I'm used to dealing with the Ford AOD's and that mother better be right, or it will burn up the 1-2 clutch parts.

The Cherokees had an AW4 auto trans.

"The Cherokees had an AW4 auto trans." Ok, why does it have a transmission cable coming up and attaching to the intake?

boxburn

AW4s do have that cable.

lawsoncl

It's not a kickdown cable that causes downshifts as in other non-electronically controlled transmissions. It regulates the hydraulic pressure, and hence shift firmness. More throttle needs a quicker, harder shift, etc. If the cable is misadjusted too loose you get sloppy slow shifting, too tight and it slams into gear. Fortunately it's dirt simple to adjust. Just squeeze the clip and adjust tight, then press the pedal all the way down and it'll self-adjust.

I kow in my '66 mustang, that I put an AOD into, that cable has to be adjusted correctly or it will go boom! I'm wondering if his came off or got loosen?

I have put that cable on an older 350 turbo and the adjustment was easy. Just for kickdown on that.
