1LE transmission fluid
Been trying to find a solid answer on which fluid to use. There are a lot of different answers that say to use ATF, some say not to. Is there something that someone can recommend?

I used a GM fluid. Worked great and reduced the second gear grind and made shifting a lot smoother. I also did the rear diff. Here is what I used.

I believe it tells you to use ATF in the owner's manual.

Any GM dealer can print you off a spec sheet on what fluids the car calls for. I have it in my glove box. I'll try to look for it once I'm home from work.

I bought Mobil 1 synthetic ATF for the change that I will be doing tomorrow. It takes 4 qt.

Changed my trans 2 days ago with Mobil 1 syn ATF. I also did my diff with Mobil 1 syn 75W-90 w/slip additive. The car is shifting much better now.
I don't track the car, I just use it as a daily driver so Mobil 1 is good enough for me. I would like to do a track day eventually and might consider switching to something better for that (like Redline). |

It does, and ironically, it's also used in the manual box in the SS.

Weird that they call it that. LOL.
I remember i changed my transmission fluid with Mobi1, but i dont remember it said ATF. this was on my LS though, so it might be different for the SS.

V-6 cars use 75W-90 gear lube, not ATF.

I used Valvoline Maxlife ATF it's full synthetic with a bunch of additives. Been happy. Mobil 1 synthetic ATF is good too. The Redline synthetic ATF will work also.
