I did a lookup on Amsoil's site for the proper ATF for my tranny and their cross reference showed nothing compatible, so I emailed them and they said that their new ATL tranny fluid is the only compatible product for our tranny.

Anyone know when this changed? I almost bought 14 quarts this weekend - I'm glad I didn't.....I guess.....

Sorry, I see the year difference now :eek:

03s use III and 06s use VI , which is Low-Viscosity :weird:

(From Amsoil site)
APPLICATIONS
AMSOIL Synthetic Low-Viscosity Automatic Transmission Fluid is recommended for automatic transmissions and other applications requiring DEXRON® VI, MERCON® LV, SP or Toyota WS.

AMSOIL Synthetic Low-Viscosity Automatic Transmission Fluid is backward compatible and replaces DEXRON® III fluids in older GM automatic transmissions. (DEXRON® VI specification supersedes the obsolete DEXRON® III in GM vehicles.)

The switch to Dex VI was made backwards compatible. So even for the 02's and up, go to Dex VI. The multi viscosity fluids are Ok, But a specific spec fluid is what I prefer. I know RedLine D6 is one, and possibly Royal Purple.

My neighbor owns a Cottman Transmission franchise and more than once he has told me that their technical people in corporate DO NOT recommend synthetic fluid for our transmissions. They only recommend the GM DEX. I've asked why and he says "That's all they say and I trust them". I run full synthetic everywhere BUT in the tranny. :thumbsup:
