Ok, first off, I've already bought the stuff. So, I don't need suggestions for tranny fluid. I've tried searching, but have yet to find a "this is exactly the Royal Purple product you put in your tranny" answer.

I'm a little confused, here's my deal. Got in on a discount for some RP products. Got myself from tranny fluid pretty cheap. It came in yesterday and it's the SyncroMax product from RP. It's shaped like a gear oil bottle which triggered my concern. RP's website states this product to be formulated for manual transmission where automatic transmission fluid is required.

NOW...just below that product is RP's Max ATF which says for GM Dextron III applications.

OK. Well, I've got an M6, it needs Auto Fluid...but the badge on the side of the tranny says Dextron II...see what I mean?

Any help?

 

You need the RP's Max ATF which says for GM Dextron III applications.

 

Well, crap!

Thanks for clearing that up. I'm sure the guy will swap it out with me, and if not, then I can probably off it on eBay.

 

Well, after I got that info from you.

Here is a reply from Royal Purple:

I guess I'll go with what I got.

 

I was thinking of switching my tranny fluid to RP too, Has anyone else used the Synchromax? how did it work out?
