Tremec TR-3650 transmission

The TREMEC TR-3650 is a 5-speed manual transmission for longitudinal engine automobiles. It includes a 5th gear that functions as an overdrive gear, light-weight aluminum housings, a synchromesh reverse gear, and synchromeshed helical cut forward gears. It is manufactured by Transmission Technologies Corporation and is rated for convert|360|ft.lbf|N.m|abbr=on of torque. The loss in power transmission efficiency is rated at approximately 16% in 4th gear for a 2005-present Ford Mustang GT.

Gear Ratios

TR-3650 used in the 2001-present Ford Mustang GT

*3rd: 1.320:1
*4th: 1.000:1
*5th: 0.620:1

Note that in the other TR-3650 applications, the gear ratios are the same with the exception of 5th gear.

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.
