This is a 1996 2.5 tl that i received as payment for a personal loan.It had 105,000 miles at that time and i did not drive it much,but was running very well.My niece used it for aprox 12,000 miles.I had to take off the seats and center console as soon as i got the car back(did not drive it at all before doing this)in order to clean it well. Now the car runs well,but does not shift into overdrive.It upshifts i-2-3 very well and downshifts well too.The fluid level is good and the fluid is clean.Are there any electrical connections that i may have disturbed?Is there any o/d switch?Thanks for any help.

 

We don't have overdrive with our cars or are you saying that your car does not shift into 4th gear?

 

Don't know about the 3.2, but at 70mph my 2.5 is around 3k and from what I've seen thats about normal. I thought mine wasn't shifting either but from reading on here that seems to be normal.

 

Torque converter lockup may not be occuring. If you go up a slight grade w/ cruise control set to 60mph, the engine rpm should stay constant as engine throttle opens to maintain speed. If engine speed increases 100-300 rpm, then lockup is not occuring. I have this problem on my 97 2.5TL. It's a hydraulic trans problem (not repairable w/o removing trans) and sets code P0740 (engine and wheel speed mismatch due to no lockup).

In any case, I would check for transmission codes w/ obd2 scanner to see if any are there. Some codes don't cause D4 to flash or CEL to set.

good luck
