I going to change the fluid in my 3550 and just want to know what the best is. I have searched and there is very little about what to use. I know they prefer the GM syncromesh, but what is the other fluid i can use?? I just dont want to pay $10-12/qt.
What type of lube is recommended for my TREMEC transmission?
The following types of lube are recommended:
TR-3550/TKO - GM Synchromesh or Dexron III
TR-3650/T-45/T-5 - Dexron III
T-56 (Ford and GM) - Dexron III
T-56 (Viper only) - Castrol Syntorque
