Check the sticker on the inside of the door frame, driver's side. Under the section 'TR', a "6" indicates a T-45, a "K" indicates (you got lucky and got the) Tremec 3650.
You must be shopping for an aftermarket shifter? Just guessing!
Welcome to StangNet!!!
The way I found out that I had a T-45 was by the drain plug location. The ford technician showed me, but I forgot what he said. I think he said if the plug was located high on the transmission then it was a t-45, but if it was lower then it was a t-3650.
So I ordered a Tri-Ax for a t-45 and it fits.
Sorry I was vague, but it was last year that I finally found out what transmission I had.
Thanks for all the help. I am looking for a shifter. It sounds like most of you like the tri-ax. Last time I was part shopping was back in '94 for my 5.0. Alot has changed! It's great how everyone is here for the love of our stangs! This is my 5th! Can you say addiction!
Many people love the tri-ax and almost as many swear by the Pro 5.0. I'm in the latter group. The Tri-Ax has a twisted 'stance' more like the OEM, hense it's name, whereas the handle is tilted over toward the driver. The Pro 5.0 is shorter, straighter, with a steel handle, the Tri-Ax is aluminum. Both are quality units. But, we have both and my wife and I both prefer the Pro 5.0 in my GT.
