Yes it is worth it. These 4L60e/65e transmissions blow up under a good amount of power.

I have the tru cool 40K, both servos, and it is tuned for faster shifting and line pressure is boosted. My 1st gear just started slipping when I load it on my converter about 2 months ago at 106K miles. But I drive very hard.

I'm talking about on a more stock vehicle than yours. Hah, your launching hard in a cammed suburban with an aftermarket torque convertor.

I never hit the 3-4 shift @ WOT

I would still do it. I did those mods before I had my cam and stall in.

I wouldn't boost the line pressure though if you did both. It will shift HARD. I would get it tuned for faster shifting though. Justin at BB tuned mine.

what do you think he did to tune it for faster shifting? I'd bet He increased line pressure :)
