The Tremec 3550 and TKO are the same except for the input and main shafts. The input will be GM fine spline and the output shaft is larger in diameter requiring the C6 style drive shaft yoke suplied with the transmission.

Hi Tim

Thanks for the help..I likely have what I expected, just that the tag threw a scare into me...I did have to buy the fine spline GM clutch and pressure plate from centreforce for my builder, who had supplied the tranny.
So I assume I have the TKO, which I was charged for.

26 spline input and 31 spline output! Plus you will need the McLeod adapter for the FE bell housing unless your builder shortened the input shaft....
Regards, george
