In the 06 mustangs are the same automatic transmissions used in the 4.0 and GT?
Are the same standard transmissions used? I know the 4.0 has and external output shaft balancer. any other differences?
I know the ovious differences of both are the bell housing/ mating to the engine block?
For the automatics the 4.0 and GT get the same tranny with slight differences. The 4.0 gets a smaller input shaft, not as beefy clutch pack... but is basically the same tranny...
I heard that the V6 Trany was only safe up to about 350rwhp, while the GT was good through 450. Watcha think?
assume you are talking autos? Lidio at Alternative Auto is pushing 475RWHP with his GT through his automatic.. There are a couple of guys that are pushing 330ish through there V6 autos...
Suspension is different, base wheels are different, for my '06, the GT was longer and wider but only by fractions of an inch due, I believe, to the different bumpers.
V6 uses a Tremec T5
GT uses a Tremec 3650
the 3650 is a much higher capacity transmission and much quieter generally.
The T5 in my 05 V6 is noisy compared to the T-5's in the previous 88 and 90 5.0 that I've owned in the past.
Th 3650 in my 06 GT is quiet, shifts faster. I've considered trying to get one for the V6 if it would fit....
That's more a function of the 7.5" rear on the V6 vs the 8.8" rear on the GT.
That might be a good part of it... BUT.. my understanding while the V6 and GT automatics have the same model tranny there are some difference that make the V6 version less robust...
