I've been using Redline MTL in my Tremec for 5 years with no problems. Tremec recommends Syncromesh by GM.

So that means the 75W90
Amsoil is equivalent to like a 5W40 motor oil...
Which now makes sense. Anyway, I just ordered GM synchromesh but Ill keep the
Amsoil in a jug when I drain it. ($30
synthetic flush...geeez)
