hey guys, i just got my XJ back from the mechanic after a couple days, i had some dieing, sputtering issues and also a broken water pump and serpentine belt. Lately i've been having some little tranny slipping issues, where if i just push the gas on a hill or straight away to keep my speed, the RPMS will go up like normal when i step on the gas but then immediately drop down, and then it takes quite a bit of throttle to get back into gear, i dunno whats wrong, but its not tooo bad. I asked thhe mechanic what i should do and he told me that no matter what do not let ANYONE push me into flushing the transmission or changing the fluid, cuz it could loosen stuff that isn't lose right now, in otherwords, if its not broke don't fix it. But i was just doing a search about flushing the tranny and came across quite a few threads whhere people say theey change their tranny fluid very often and i had some people tell me that maybe a fluid and filter change would make my shifting better. I have 117K on it now, 1990, AW4 auto. I'm not sure if the fluid has ever been changed or not. What should i do?
