Thread: GM synchromesh - FRICTION MODIFIED tansmission fluid

Has anyone here used or have been using this? Just wanted to gather some information from anyone on the forums that has. I recently did a Sr16 transmission swap. And I paid more for Pennzoil than I did this stuff. And after talking with Serban, he had mentioned that another car friend of his has been using this and prays by it.

Anyone car to chim in?

Penzoil is what I use. The gm stuff is supposed to be exactly the same.
