When I called to ask for recommendations on replacement fluid, they said Pennzoil Synchromesh.
One of the benefits, BTW is because it's not ATF, it doesn't have the expansion properties that require you to fill and then drain some of the fluid out. He said a very common failure is filling the unit up with ATF, not draining the required amount and developing leaks in seals due to case pressure.

Thanks, I did not drain any when I replaced my fluid with Amsoil ATF last year, this isn't mentioned in the manual afaik. I hope my seals are ok! I've been considering replacing tranny fluid again, will go with the Pennzoil. The Amsoil ATF is working fine though, no complaints.
