Are these only available as complete units? Is it possible to sell them as upgrade kits (i.e. gears & countershaft)?

They were actually in the 2001 1/2 and up GT's,01 Cobra and the 03/04 Mach1 too! Like the Forgiving overdrive of the 3650, the T-45 is higher reving in 5th but a smoother shifting gearbox so it's a trade off for a car that sees frequent highway driving..

The one thats pictured must be pre-05 as the 05 and up have a different tailshaft housing to accomodate the output shaft flange. Just wondering if there is an upgrade kit for my 03 GT or would I have to purchase a whole complete unit???

A number of suppliers have upgrade kits like American Powertrain!
