Recommended Oil and Fill Capacity
TREMEC engineers have recommended Texaco-Havoline Dexron III/Mercon Non-Synthetic ATF. There has been a significant amount of confusion regarding the proper capacity and proper type of ATF for the TR-3650 which may have a correlation with a rather large number of complaints about notchy shifting, shift "nibbling", noisy synchros, and grinding gears. The 2007 Mustang GT owner's manual specified the use of 3.0 L of non-synthetic Mercon ATF in the 3650, while the 2008 Mustang GT owner's manual now specifies the use of 3.0 L of Mercon-V ATF in the 3650. Dexron III/Mercon Non-Synthetic ATF seems towork best for pre-2005 Mustang GTs.
NB: Tremec service manual also specifies Mobil 1 Synthetic ATF ( Tremec specification ET-M-99 ) in addition to Dexron III.
