One thing I would love is a canbus integrated radar. - Where the display shows up on the DIC and the vehicle chimes give the warning. Plus, if you listen to your music loudly, it can turn down the volume during the warning and back up again.
The part that isn't rated for constant duty is the ball bearings in the control actuator lever. - Its the part that actually applies the clutches in the TC.
The balls are 13mm (0.512) in and should be made of a hardened steel. - GM went cheap on this part and they degrade. Jeeps run the same case that is constant duty with the hardened ball bearings.
