When did you last replace trans filter and fluid? Dirt may be causing shift valve to stick.

God bless you

run fault codes and look for TCM fault or OD servo/sensor fault.

could be a solenoid
low oil
worn overdrive friction discs

you can source a used transmission from a wrecker
and drop that in

from the pictures i cant tell if its overdrive is under an external plate at the end of the gearbox
and repaired with an overdrive kit

you ha burn clutch overdrive clutch you need to replace your transmission

Normally while driving in overdrive (4th gear) you will feel it start slipping and finally slide into third gear. Then 3rd gear slips out into second, and you will never see 3rd or 4th gear again. I'm guessing this was the problem? If so its time for an overhaul

It is possible that the computer is the culprit. Most cars with computer controlled trannys will keep in 3rd gear and only shift to overdrive when the engine has warmed up sufficiently. It could be a problem with this system. The best place to take it is your local AAMCO or Mr. Transmission, or the dealer. A regular garage will just be guessing in some cases unless the problem is revealed after running the engine codes.

you need a rebuild, your overdrive clutch is worn out. do not drive in overdrive until the trans is rebuilt.

sounds like a stuck valve. I'm still new to transmission stuff so I could be wrong. he could probably get a transmission rebuild book and maybe just do it himself. it would be the cheapest unless you knows someone
