cooler and shiftkit are reccomended. with those and tuning i would say the durability should be close to stock. just a verter and your asking for trouble- they create ALOT of heat. especially since you are not going to waste your $ on anything under a 3500 stall speed

I believe you would see (say) ~90% efficiency under
higher slips (the ~3000RPM are considered "mild" and
have reasonable peak efficiencies but when you slip
you are not too efficient.).
So call it a 10% loss. 10% of 300HP flywheel output
(just by way of example, no disrespect intended )
would be 30HP or about 20kW of heat to the fluid.
Mmmmm.... toasty.
Fortunately it's rare that you'd sustain that kind of
output for long, in a high slip regime. But you'd like to
be shed of that heat by the next episode, for sure.

I have over 115K on my Z28, with a 3500 stall since 4XK mile with no problems. I have a 25000 GVW B&M cooler that I run post-radiator in the summer and pre-radiator in the winter.
