Need help identifying Tremec trans.

[MrNova]

I have a Tremec trans n need help identifying it. It has three sets of numbers on it. They are as follows:

Top front: C-2605803

Driver Side top rear by shifter mount: C-2606415

Driverside Middle: C-2605865

Any help is very appreciated as i'm new to the Mustang world n Tremec transmissions, thanks Mike.

most common is the T-45:this is probably what you have came in most mustangs

then you have the TR-3650: came in 01 and up GT's

If it's a six speed it could be a t-56:

:cheers: welcome to the mustang world

I actually just found a tag on the tail housing and the numbers are as follows:

TR3550 AGAEG 25
2600682 0098

I hope this helps in identifying it. It seems to be a 3550 but which version? Thanks again, Mike.

Well thats probally not gonna work with a pretty decent aluminum headed 306 with 10lbs. of boost from an S-trim. It seemed hard to shift under full power. And thanks for the help Boss, Mike.

Don't mean to steal the thread but I have a 3550 and was wondering if any of you know what shifter is best for it Pro5.0 or MGW. Thanks.
