Well, I'm getting ready to drop my trans pan again and change my trans fluid and filter.

I did it last year with 30k on it, now I'm @ 56k, I used Mobil 1 atf and had no issues.

looks like it's been updated -

Dexron III, Dexron IIIE, Dexron

Approved for H specification, the latest GM Dexron III performance level

So I'm getting ready to do it again in the next week or so, and use the Mobil 1 trans fluid again, but I guess this time I should also get a new gasket right?

Get a new gasket. And look into Dexron VI. Its most likely still only available at dealers. The specs on Dexron VI should be highly competitive with those of a Synthetic Dex III.

so that is the fluid you guys recommend? I am at 70k and the trans fluid has never been changed. So next week I will be doing the pan drop and trans fluid change as well as a ignition system flush.
