Do I need to replace my drive shaft slip yoke when installing a T-5, Tremec 3550/TKO/TKO500/600?
Both T-5 and Tremec 3550 use a 28 spline yoke which is the same as a C4, toploader or AOD. 3 speeds and T-10 4 speeds transmissions used 25 spline slip yoke so a replacement is needed. Tremec TKOs require a 31 spline outshaft, so a 31 slip yoke is required. C6 also have 31 spline output shafts. Call us if you need a replacement yoke.
