What is the best way to change my Tranny fluid on my 1995 Buick Century?

DAGS and you will find quite a bit on how to service your tranny. It's a very do-able job. As for the Tranny "helper" fluid, I'm no believer in magic elixers. Keep an eye on your fluid, change it at 50,000 miles, and it will love you for life.

They why change it? I'm a believer that it should not be changed (unless burnt or otherwise damaged). Only car that I ever had the fluid change is the only one that ever needed the tranny rebuilt.

Why shouldn't it be? My Regal was just traded with 148,000 miles and never changed or added fluid. My Cutlass was junked at 185,000 with a perfect running trans and never any serivice. The list goes on.

I don't trust the magic potions and see no need for them.

Don't bother changing your fluid it will last life of the tranny. Repair shops recommended changing as an plus sell all it did was loosen and distribute filings through the unit and cause problems .

Just drop the pan, change the filter (if applicable) and gasket, reassemble, and seal. Stick a magnet in a corner of the pan to catch any filings, if there's not one there already (or a magnetic drain plug.) You won't change all of the fluid, but unless you're having issues, this will be good enough if you do it every 50K or so.

If you're not having any issues, I wouldn't use anything but the recommended ATF.

good luck,

And if you are having issues, some magical fluid is not going to put metal back on worn parts.

Don't. The designer and manufacturer of your transmission doesn't recommend it, and consider that they once warranted it, while the maker of the tranny helper has never warranted a single transmission. Just drain and refill with only Dexron III every 25,000 miles.

I think that is the lowest mileage interval I've ever heard suggested.

You must own a lot of stock in the Dexron company. Why 25k?

Dont use any additive.

Pull the pan, change the filter, clean the pan, and refill with the proper fluid.

And dont listen to people like Sal.

Service the tranny according to the manufacturers instruction, and let it go.

I gotta go out to my car and see when i had the new rebuilt tranny put in.

(FOR $1,550.00)

I'm not very familiar with GM transmissions (only one ever failed on me, at over 290,000 miles, had 30,000-mile fluid changes), but Dexron and pan gaskets are cheap compared to rebuild jobs.

If you work at Jiffy Lube, the easiest way to change ATF fluid is charging $99 for the service and not even doing the service. A lot of Jiffy Lubes were recently exposed/busted on a Dateline NBC type show. They were caught on camera recommending ATF changes/charging for them/and then not doing them. Also not changing filters. When confronted, they said "oh we just forgot to do the service." They forgot to do a $100 service 7 out of 10 times?????

AVOID JIFFY LUBE LIKE THE BUBONIC PLAGUE.

Also, the way that Jiffy Lube changes ATF, when they actually perform the service that is, is that they attach a vacuum cleaner attachment like thing to the dipstick and suck out the ATF. Instead of doing it the right way and removing the pan, so as to get all the gunk out of the tranny, and then replacing the pan filter.

1) Drop the pan, clean the pan, replace the filter, reinstall the pan, refill the amount drained out. 2) Use some hose to do a home mechanics version of a flush until you get nice clear new fluid coming out. Lots has been written on the 'net about this. One source is:

Thanks 4 all the info,

just looked at when i had the new rebuilt tranny put in,

it has been about 50,000 miles,

fluid still a nice light pink,

shifts good,

don't think I'll do anything to it for quite a while.

Hey funk, p=l=e=a=s=e change the fluid at least every 50k miles. I hope you did not mean, just above, that you were not even going to do this when you said "don't think I'll do anything..." A car will often treat you like you treat it better so than a person will; often, I said. s
