I'm planning on changing my tranny oil for my 04' mustang gt. I was wondering what the most favored tranny oil for our cars is? Anyone have idea bout best oil?

 

just get regular ATF. I used the pennzoil stuff they sell in walmart and haven't had one issue. Also make sure you put the proper amount in, and do not go buy the manual. 3.2 quarts is what the tranny needs.

 

^^^ likewise as above but Im a advocate of Mobile 1 (period). But ya know, you'll prob get a bunch on guys on here argue'n about which fluid is superior over the rest. Just pick a well know reputable brand and be done with it.

 

Mobil 1 ATF is what I used and was very happy with the results.

 

i like to add a little bit of lucas's brand transmission fix in my T45 too. but yea, i use mobile 1 synthetic

 

manual trannys DONT have filters correct? Or do they?

 

that is correct, just a normal drain and fill procedure
