I've heard either Transynd or Torqdrive. I personally used Torqdrive from one of our vendors here.

Im in Switzerland at the moment, those oils are not available here.
Can I use Dex III or VI?

Hmmm not real sure. I'm thinking yes on Dex III but not sure.

I would ask MikeL about what to use, I think Transynd may be too abrasive for the upgraded transmissions or something of that nature.

X2, If I remember correctly, he said he uses DexIII with a additive. I would call him and find out.

This is correct. Alto and Raybestos plates are different than the factory. He recommends DexIII.

Thanks guys,
I called Suncoast yesterday, and they also recommended DexIII.
They advised me NOT to use any syntetics!

What's wrong with using Transynd synthetic in a Suncoast build ?
