What are the gear ratios for the 2001 Gt manual transmission. Specifically, what's the over drive ratio? I know the '03s have a .62 ratio.
Thanks,
P

2000 GT and early 2001 is 3.37, 1.99, 1.33, 1.00, 0.67 for a T-45. In mid 2001 they changed the trans to the 3650.

I talked to a tech guy at Tremec and he seemed to think that the "2001" GT's had the 3650 and a higher 5th ratio of .67. He also said that they don't directly support these "ford" trannys but that I should get parts from directly...

Last year when I was looking to get a shift for my 2000 GT I checked many places. This link to the FORD shifter says M-7210-N # Fits 1983-01 Mustang with T-5 or T-45 transmission

The instructions show you how to tell if it is a 3650

2001-2002 T-3650's have a 0.67/0.68 5th gear


In 2003 they went to the 0.62 which is the same ratio as 6th in the t-56 used in the Cobra

He is right

Up til mid 2001, the trans was the T-45.

Around mid 2001 they changed to the T-3650 with that 5th ratio

In 2003, the t-3650 went to a 0.62 ratio
