Synthetic trans fluid

In a 700R4--who runs it, what kind and how do you like it?

Pros and Cons too.

thanks

10 qts of Mobile Syn in my 120k mile 700R4 and it dont slip even with a 2400 stall. Its pricey but oh well.

Amsoil synthetic, with 85,000 miles on this rebuild. Amsoil synthetic lubes throughout.
