Most 2007 Mustangs offered two primary transmissions: a 5-speed manual Tremec TR-3650 and a 4-speed automatic (Ford 4R70W family). A high-performance Shelby variant used a 6-speed Tremec TR-6060.
Overview of standard transmissions in 2007 Mustangs
The following list covers the two main options that were available in the non-Shelby 2007 Mustang lineup. The manual and automatic choices were paired with the available engines and trims.
- 5-speed manual Tremec TR-3650 (used on V6 and GT models)
- 4-speed automatic (Ford 4R70W family)
The standard V6 and GT models could be equipped with either option, depending on customer choice and production specifics. The manual is favored by enthusiasts for shifting feel, while the automatic offered easier, smooth driving in traffic.
Special variant: Shelby GT500 (2007)
For the 2007 Shelby Mustang variant, Ford used a different 6-speed manual transmission designed for higher performance and torque handling.
- Tremec TR-6060 6-speed manual ( Shelby GT500)
This 6-speed setup was exclusive to the Shelby high-performance edition and not offered on the standard non-Shelby models.
