The transmission may be worn out by now, should go to a transmission shop for proper diagnosis.


If you're on a budget and handy, check the vacuum modulator and line to it, it's a simple enough fix that might save you a trip to a shop.


I don't think there is one on there KenF.


hmm I checked again, repair manual shows a vacuum modulator ...


Found one, I know its around the time they did a redesign. So I agree with KenF. the modulator valve or vacuum line you should check out.
