I have a white 2004 mustang GT with a 10,000 mile old t-3650. I'm at 37,000 miles, so I'm out of warranty. I have already argued with ford, to no avail.
My 1-2 and 2-3 shifts are shot, 3rd gear is unusable. Went to ford, they said there's nothing they can do other than replace it, which is 3500 dollars.
With this said:
1)Rebuild. Costs around 2500 dollars after everything's said and done, this is my 1st option.
2) New t-3650. About 3000 dollars from a reputable place installed, I don't really want to do this because my transmission is less than 10,000 miles old, and I'm afraid of the same damned thing happening again.
3) T-56 or other six speed? This is where my real question lies.
A) how much could I get one for? I found one (Rebuilt or new.. Can't remember) for about 1500 (including core charge)
B) would there be more involved than a tranny swap and a new shifter/boot?
C) I've read in places that you need a shorter driveshaft for the t-56... Is this true?
4) Do you guys have any other suggestions on good transmissions? '
Anything under 3500 dollars is doable.
Thanks for the help. (here goes my college fund

)
One more question. Is there a specific transmission-only forum? I was fairly confused as whether or not to put this is 4.6L tech or general tech. Thanks!
