I found a brake for my 4l60 and was wondering if it was really worth it. the car is mainly street/strip. approx 600 rwhp. A little background on the trans is 5 pinion planetarys, alto red clutches, hardened output shaft, all wave/bellville plates replaced with flat steels, shift kit, wider band, new reverse input drum, and im sure im missing something. but is the trans strong enough to handle it? and is it worth it?

I personally wouldn't trust it imo

We don't build any transbraked 4L60e transmissions without 300m chromoly output shaft. The added "hit" the shaft takes with the trans brake will eventually fail a stock or hardend shaft. When the shaft breakes it will splinter and blow the back of the cause out ruining your transmission case completely. I wouldn't recommend it with a hardend stock shaft.
