I have a rebuilt T56 with lots of miles on it, getting ready to do a fluid change. It has CF blocker rings in it, and I was told by the builder many years ago to go with Mobil 1 synthetic ATF, which is what I've used. But now it's very hard to find, or stupidly expensive where I do find it. I've been looking at the 88861800 GM fluid and Redline D4 ATF, is there one you all would recommend over the other? Is the 1800 safe with the common T56 upgraded parts?

Amsoil Torque Drive. The best for these 6 speeds in my opinion.

What's the best place to buy that from, straight from Amsoil? I couldn't find it on Amazon or Summit.

You have to find a dealer or the only retailers that can sell it are Advance Auto parts or Napa. That's if the store is signed up.
But sending you a PM. I can take care of you.
