4l60e Hummer h3 upgrade.

Hello, dear friends.
What do you think about RAYBESTOS Z-PAK High Performance Clutch Assembly for 4l60e ? Is it useful thing or just money wasting ?

Main spare part for my Hummer while off-roading - sattelite phone !

I have the Z PAK , wide band, 5 pinion planetaries, etc. and I think it is one of the sweetest trannys that I have ever owned. I am using the BANKS program to manage the TCM and I am totally satisfied with the pattern on the street and the trail. Suggestion: Clip the flexible cooler return hose about 1 1/4 inches from the crimp on the line that goes back to the transmission, shorten the tube that comes from the radiator and install a 3/8 MAGNEFINE filter. After a few miles of driving, replace the filter.This will remove any "break in" contaminants and really enhance the performance and durability of your rebuilt unit. LOL

Well, no garage and -4* F out. This sucks.
