i have a 1998 olds bravada. it has a 4.3 engine 4 wheel drive automatic tranny. now the problem doesn't happen all the time but it does happen when im driving. ok when im at a stop or leaving to work i accelerate and and sometimes the rpm gauge will jump up a little higher than i am accelerating then it will jump way down. when it jumps up it goes to about 3000-3500,and when it falls it goes to 1500. it also seems to be idling a little high when im warming it up but i think that's because its been very cold out here(chicago). im hoping its not a trans problem. i also noticed its making a very hard growling sound when i accelerate. i checked the levels on the oil and trans both are good, i had the trans flushed and oil changed. it only has 76000 miles on it. is there anything i should check. or can a diagnostic check the engine and trans, i know more about the engine than i do the trans. to me it doesnt seem to be running the same since the tranny flush but it could be anything. i want to take it to a shop but the last 2 have gave me bad advice and changed parts that prob didnt need to be changed or couldnt find the problem and started guessing what the prob was. n wanted to start doing repairs that prob didnt need to be repaired which would put alot of money in there pocket and not help the problem. so what can i do first before i take it in what should i look for. most of all the repairs i have done so i am capable of doing the repair myself but the trans i know nothing about except checking the level. so any help will help before i take it in or back to firestone. but even they said if there is something wrong with the trans they wouldnt know what to do (i know nice for a place that offers a trans flush and not really do repairs on trannys). so thanks for any advice, and if you have any questions about this problem leave your email and i ll email you back. thanks again
