My 99 xj has a problem with its automatic transmission. It will shift from first to second at 4000 rpm, but will not shift manually through gears. If anyone could help me figure out the problem i would appreciate it.

 

Tcu?

 

I was told thats a possibility. Would i have to drop the pan to get at it?

 

Could it be the governor pressure sensor?

 

It might actually be in the cab, behind glove box.. I could not tell you for sure.

 

Dunno what that is, but what about TPS, or maybe IAC valve?

 

Thanks brother i appreciate it. Hopefully its just the tcu thats already gonna set me back $200. I know theres three other sensors when i drop the transmission pan as well so hoping none of those need replacing too

 

I just replaced both of those a month ago. Still a possibility if one was faulty it does happen

 

Didn't they combine the tcu and ecu in 99?

 

Hope this attachment works and the file's not too big. Manual for the AW4, great assistance in understanding operations and troubleshooting.
Didn't work, file format is too big. Try google "AW4 Transmission" to locate the manual.
From your description sounds like some pressure issues and perhaps solenoids.
