Question about 1989 Buick Regal

1 Answer

I have a 89 buick park avenue ultra. my

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. my 89 buick regal limited with the 2.8 is doing the same thing. i have a kick down cable or some tranny valve that is stuck. now my trans will start in first gear and then slip into second but will not shift past that.

    yes my fluid is a light brown but has some redish in it. its been stuck in gear for a long time now and nothing i do gets it to change, but recently i just got mad and foored it and got to 84 mph and the motor was all at full rpm and then out of no where it shifted into third i was extremly extcited and the lever worked again i can put it into first and it shifts into first now. but shortly after, it got stuck in 2nd again. so i sped it up again today and sure enough went into third gear and now it will shift into gear now but only if im going faster than 40. and i jump on the gas alittle and fall back it will shift. now im just confused because of the fact it is going into 3rd. so what type of problem do i have now?

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.

I have a 89 buick park avenue ultra. my

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
