T-45 Transmissions - The T45 Source!
Pro-Force Performance is proud to continue the tradition of providing custom-built T-45 transmissions as well as custom parts for the T-45 that were formerly available from TheT45 Source. Yes, Pro-Force acquired "The T45 Source" in the spring of 2016.
Which Mustangs used the T-45?
1996-1998 Mustang 4.6 GT
The T-45 is a smooth shifting transmission even at high RPM, however, Pro-Force rebuilt T-45s have the upgraded carbon-fiber synchro rings like those used in the T-56, and the billet bronze shift fork pads.
Parts are increasingly difficult to obtain for the T-45. Ford has discontinued all parts for these transmissions. For this reason many are converting from the T-45 to the stronger TR3650. Interchange information is posted below.
Pro-Force offers "Built" T-45's with custom parts that resolve the various "issues" that have been inherent to this transmission over the years. Available enhancements include: 26 spline input shaft, Cryogen Tempered gears and forks, a redesigned single-disconnect reverse gear, and billet shift forks to name a few..
All of our T-45 transmissions are available in 1996-1998
GT or COBRA versions as
well as the 1999-2001 versions.
