Thanks Keppelj,

Sounds like something to try.

Any known side effects to the moly? Leaks or ???

Amount to use?? The 10% was the product solution itself, right?

I've used the mix for a year now with no leaks, wicking, other problems. Checking my notes, I used GD-421 (75-90wt) additive in both the trans and final drives and the ratio was 4 oz GD to 28 oz gear oil for 32 ounces, 12.5%, which is their recommended mix. Here's the link:

As a post script, I see there is a newish tread on this subject in the MOA forum in the Oilheads:

Just to update on prior comments I have made on my sticky downshifts. 4/3 and 3/2.

I took suggestion of using guard dog moly. Drained and refilled with proper blend of moly and BMW Synthetic 75/90 tranny oil.
Today was first day to put any miles on it. A few short runs prior as weather permitted. 110 miles today from sunny Portland.

I am impressed. All shifts were smoother with or without throttle blips on downshift. The worst thing I felt on noted downshifts was slightly notchy but absolutely no sticking as previously noted. I am convinced that with the characteristics of this tranny, this is as good as it gets. and that "ain't bad"!!!

Thanks for suggestions and comments. =D>
