What hears does it have from the factory? i was thinking 3.55 or 3.27

3.27

oh ok thanks, my neighbor wanted to know. He's thinking of going 3.73.

Has he thought about 4.10s?

yea but his son who is 16 is soon going to be getting it. and since he'll be driving it alot he probably wont want the MPG that 4.10's give you.

4.10 will change the MPG by like 1 over 3.73s

i saw a video where a guy had 4.10's in his 01 gt and at 70 in 5th he was running ~2100 RPM's. which is too much for a teen that can hardly buy gas for the car lol.

2100rpm.... when i had my 99 GT with stock 3.27 it ran 2000 rpm at 70mph. did you mean 3100 maybe?

thats odd, mine does around 1800 at 70 in 5th..hmm

I paused the video at 70mph and it read 2400rpm.

But my gt was always exactly 2000rpm at 70mph. did the t45 and the tr-3650 have the same 5th gear ratio?

hmm i have no idea. i dont much about tranny's :lol:

T-45
1 - 3.37
2 - 1.99
3 - 1.33
4 - 1.00
5 - 0.67

T-3650
1 - 3.38
2 - 2.00
3 - 1.32
4 - 1.00
5 - 0.68

2003-2004 Mach T-3650's have a 0.62 5th gear. (I am not sure about 2005+ Mustang 3650's 5th gear.)

Ditto for my 97' GT
