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 to work 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. Note that Tremec engineers have also recommended GM Synchromesh as the transmission fluid. Note Mal Wood Automotive, an official authorised Tremec distributor in Australia, have consistently recommended use of Castrol Transmax Z for use in the Australia Ford vehicles.
