CDT35RL2.5/80 offers 50% more clutch apply area than stock. G3® friction material is formulated to achieve minimal wear & maximize heat resistance. Keyhole Clutch design allows a significant amount of ATF to escape out of the O/D and I/D channels to improve clutch engagement. The pooling of ATF in the slot and hole separates the friction and steels when the clutch is disengaged reducing parasitic drag and heat build-up. Kolene® Steels provide a surface treatment the enhances wear & fatigue resistance.

We do not include welded hubs in Kit. In the beginning of R&D on this transmission, we thought this area needed strengthening. However, in all the units that we've rebuilt, we've NEVER seen one broken. Therefore, we deemed it unnecessary. Also, we do not include a billet pump rotor because the factory pump rotor has proven itself reliable (we have never seen one broken) unlike the 4L60E.
