ok i ahve a 91 sedan deville that has 212k miles on it... motor is running strong but now i think the tranny is having problems... the past couple fo days it has been acting up... i was on my way down to the shore and i realized that when i pinned it it would just rev up real high and hit the rev limiter and not kick down...that got me pissed off.... after a while it went back to normal.... yesterday i couldn't take off fast because it would hit the rev limiter again and bog down the car.... again after a while it cleared up..... some ppl tell me it is the filter... some say it is my cadilic converter.... it has a tranny leak... coming from the line in teh back of teh trans but it is a slow leak and i check the fluids everyday in it just to be safe... any ideas????
