97, 2200, has 76,000 miles auto should i change the tranny fluid or leave it alone, i have heard on some car somtimes it can be worse to change it then to leave it alone?
I've heard that too and I don't know how its possible unless people are using the wrong fluid. Anyway I change mine once a year and have never had a transmission problem out of any car. If you have the manual trans the Penzoil synchromesh fluid is the same as GMs but costs less. They should have it at Autozone.
yea i have just heard that your tranny gets used to being dirty then when its clean it messes up but mine is auto thats why im worried about this?
mine had 160k miles i drained it 15k miles later its fine.. its an auto
awsome thanks alot!! did you have it done at a shop where they suck it all out n clean it or just drain and refill?
no i did it myself.. its just like 10-12 10mm bolts its quite easy..
one BIG thing to remember i dont think its good to FLUSH the tranny OR the engine when there that old. Thats when i hear of problems if you just drain and refill it should be fine. Just get a big pan on the floor losen the 10mm bolts all around the tranny pan. Let the fluid drain for awhile. While its draining clean the pan as good as you can the gasket is reuseable but if theres any notice of wear ect you should change it
i was fine with mine. just make sure you clean it very good im not sure it the 4 speed and 3 speed trannys take the same amount but the 4 speed autos take about 7.5 quarts after draining the pan you may want to check on the level.
also make sure you replace with DEXTRON fluid
Can anyone comment on the change noticed with chaging the fluid? My car has 96k miles and is on the original fluid, has been driven hard around a city all its life. The trans is sloppy and loose, so I'm planning to change it. Is there a night-and-day difference or might the trans just be worn out anyway?
I was happy when I heard my car ran 10s. Then I found out that was 0-60.
once u do a tranny flush u shift through each gear and sit in each gear for 5-10 seconds...P R N D 3 2 1...do that like 2-3 times.

i wouldnt do anything with a flush just drain it and refill
ok thanks im just worried about blowing up a perfectly good tranny even tho they are as easy to find as water.....
honestly i'd take it to a shop and have them do a full tranny flush with the flushing machine, and ask them about additives, we use BG additives/cleaners when we do tranny flushes
I change my tranny fluid every 40K in all my automatics. Just change it, i would not do a flush on an automatic. I've never had a GM auto fail before 200,000 miles when changed every 2 years or 40,000 miles. I did have one fail when it was flushed, and i'll never do that again.

I have 01 4 spd auto 2.2L, I changed my tranny filter & fuild with Drexon III, it was changed 115,000k Ive got 135,000k now. I am the second owner of this car, Never had a problem with the transmission, I didnt do flush, Just drain & refill.
I don't do a flush either, i heard that unless u do a flush right from new, you will have trouble with the tranny when u do it. I have always drained and refilled. Don't forget to change the filter aswell
