Auto or Manual? On my manual I used RP Synchromax synthetic manual transmission fluid.

Synchromax FTW!.

my 3650 shifts 1-2 like butter. 2-3 is like the hands of god are helping you, effortless.

though the notchiness never really bothered me, unlike the whine/groan/chatter or clunk it makes, but it made the shifts butter anyways.

asper Tremec, do not use synthetic fluid in a 3650, use plain old Mercon III, unless you want major $$$ repairs somewhere down the road.

Not meaning to hijack this thread, but out of curiousity, what would you use for an automatic transmission?

which automatic transmission? 4R70W, uses either Mercon III or Mercon V and people wth C-4's should use type "F".
