Anyone using Transynd?

[Billman]

I tried this in '2500HD/3500 HD Trucks & Drivetrain' also.

Are any of you guys using it in your 4L80E?

It is accepted where Dexron III/C4 is used.

Full Synthetic Castrol Transynd.

I stumbled upon 2 Buckets at work...

Some of the Allison guys are using it. I recently asked ATS owner Clint Cannon this very question, concerning what fluid he recommends for his performance built Allisons. He recommends Dextron III because the various clutches and their friction properties were engineered for Dextron III. He went on to say that synthetic and others would probably be OK, but.... he knows Dex works.
