t-45 vs. 3650

[fast97gt]

will the 3650 5spd work in my 97gt with no probs, direct bolt, so on so forth?, if so whats the easiest way to tell the 3650 vs. the t45

In order to use the 3650 in a 97 you need a 3650 clutch and flywheel. Easiest way to tell is either get under there and look. 3650 will be beefier and typically be tagged tremec. Also look at the door code.

Technically they are both Tremec transmissions. Borg warner was bought about 1997-1998 and transfered the T-5, T-45 and T-56 line over to Tremec. Trans made before those dates have BW on them and after them will have Tremec.



Easiest way to tell?? 3650 drain plug points straight down to the ground. T-45 drain plug points to the side

the 3650 holds more trans fluid and is bigger. i put one in my 2000 gt and it was a direct bold in. didnt have to move anything and it feels sooo much better than the t-45

 

[Jbauer]

it was a 'direct bolt in'?

Unsure if the spline count on the trans is the same. The 3650 is paired with an 11" clutch and flywheel like the previous Cobras while the t-45 uses a 10.5"

A 10.5" clutch from a car that had a t45 in it previously will work fine.
I run a flywheel from a 2000 with a tr3650 from a 2002.

Yes it is.

Does the 97's have an mechanical or electric speedometer? You might have a problem there.

get an extended range speed-cal. New driveshaft as well. Everything else should be fine.

Why would he need a new driveshaft?

I was just guessing they were different in length. I have not done a t-45 to 3650 swap. Just my aode to 3650 which called for a new one.

swap

Just put a t3650 and an 03 mach 1 engine into my 98gt, the cross memeber needs to be notched out to fit the t3650 however, some people say they have had vibration problems due to not notching the proper angle. I am going to try the crossmember for a t3650 and see if it mounts to the 98

I had vibration but eventually went away. Let us know if it works!
