So you aren't changing the rest of the clutches (besides the 3/4 clutches) and bands?
The auto trans internals look way more complicated then I want to mess with.
Also why do you suppose RPM says not to dyno the car as it can hurt the transmission? I don't see how dynoing it is worse then running it down the track.. Apparently it's hard on the 3/4 clutches as well... I really want to dyno my new combo but I don't want to hurt the trans.

Another part we upgraded last time was to replace the Corvette servo with this. Also part of the Level X package.
Sonnax 2nd Gear Super Hold Servo Kit
Part No. 77911-03K
Dual seals on the 2nd gear piston and separator ensure positive band apply/release and eliminate cross leaks, which contribute to 2-4 band and 3-4 clutch failure.
It's not a bad DIY. You just need some diagrams to ensure you put the valve body bolts and check ***** in right. I got the diagrams with my last rebuild, normally part of the instructions for a shift kit.
I can't speak to the dyno warning or WOT OD. I've done both in this build and never hurt anything. I have heard that after a dyno pull it's a bad idea to go into neutral, and just let the engine decel in gear.
