Tranny fluid question...

[Phat3800]

This weekend I'm planning on replacing my tranny fluid/filter, as well as my pan--seeing how it has a big a** dent in it which is disrupting the fluid flow and therefore making my tranny slip when it's cold. Anyway, any recommendations on what kind of fluid to use? My buddy suggested Mobil 1 synthetic, which costs a bit more. Any ops on this one??

I wouldn't swap to synthetic, since you'll need to flush the whole system to do that (this only applies to trans fluid).

Buy some Dexron III labeled fluid, a good quality filter, and if you'd like an extra deep pan here's one for under $15 that GM sells

Mobil 1 ATF says its compatible with conventional ATF...why flush the system? Would it make any differences?

If it were my car, I wouldn't mix the two. I don't see what the point would be to have half regular and half synthetic.

I would stick with the stuff my tyranny was designed for, Dexron III.
