What are all the names of the avaliable transmissions that come in you all's cars?

someone told me they come with 3650s, but i thought ford put a better trans in...
also, whats the deal with the 4 speed auto and the 5 speed auto? isnt the 5 speed liek a grand more? is it that much better?

thanks guys

im just wondering

 

GT manual= T-3650
GT auto=5R55 (5-speed)
V-6 Manual=T-5
Not sure what comes in the V-6 auto

 

is it a beefed up 3650 or is it the same POS that comes in the 01-04s?

just a t-5....as in the same trans that went in like 1995GTs?

thanks

 

Not sure if the new 3650s are beefed up but they now employ a slave cylinder as opposed to being cable actuated as before. They still are crappin synchros left and right. Hell, the roller bearings on my input shaft sound like they may be rattling.

 

it might be in your clutch...the centerforce bearings rattle a lot
