Tremec have the later upgraded spec than the usual T5 is my understanding. I recall the Tremec versions have 330 lb ft rating, like the Ford M-7003-Z. Better brg and synchro rings etc. But look the same as most T5.

Could be a difference in the input and output shaft sizes. I have a Tremec and the shafts were larger. Had to get a different clutch disc and driveshaft yoke.

Tremec bought the design from Borg Warner. Those built after the company change are called by the new name. Same transmission though. And just like under BW, the models continued to vary by their application with a range of shaft sizes, spline counts, tail shaft shapes, bell housing patterns, and gear ratios. It's sort of the ultimate chameleon product - one name, many many flavors, and much of them interchangeable. I have an S10 pickup version modded to all WC mustang internals, going from a GM input shaft to Ford, and from 3.76 first gear to 2.95, but with the forward-shifter S10 shape.

Back in 2000, I bought a new V8 Camaro T-5 from work (GM dealership). On the way home from the British V8 meet in Ohio that year, it developed a bearing noise and had a bunch of metal in the fluid. It was covered under the parts warranty and the replacement was a Tremec version. If I remember correctly, I think that it had the same part number and it was identical to the Borg Warner version.
