I have a 89 buick park avenue ultra. my transmission has trouble shifting into gear. if you put your foot on the gas, it will eventually shift, but it takes a minute. I checked the fluid and it was low, but i filled it and it is still doing the same thing.

    I think it is just a problem with the valve body. I'm going to try to repair just that.

    you could try this test. engine not running after you drove it , take the dipstick take the level. then the next morning without starting the car ,take trans level if it raise , the torque converter drain back to oil pan, the probem is the input shaft seal are score or the shaft itself

The transmission breaking apart but in a really slow way. There's not a thing that can be done to save it. It's going to someday give out. You can prolong it by not punching on the pedal to test it. just drive it normally and DON"T get the trans oil change. Just leave it alone... I own 89 P/Ave 156,000 original owner. Same thing happened to my car and picked up a used trans at junk yard and my mechanic installed it and runs like a baby at half the price(700.00). If you go to junk yards half of the park ave are because of trans. Good luck

If the trans.oil is dark brown in color and smell's burnt your tranny is probably on it's last leg.If tou have bad pump pressure or low oil you will have to rev the eng to get it to build enough pressure to move.Your detent cable or kick down cable is for passing,when you step on the gas when passing someone this cable is pulled causing the trans. to go into a lower gear and when you let off the gas it should shift back into a higher gear.if it's out of adjustment it will kickdown to soon or to late.If your car has alot of miles it may be in need of a filter and fluid change,but usually when slipping occures its to late and you will need a replacement tranny.Hope this was helpfull.
