Keeping cost in mind what are the best upgrades one can do to the 4L60E. I ordered a Transgo shift kit, oversized servos and what I thought were better valves (boost and TV boost) which say on the package for 700R4 and 4L60 so I have my doubts tyhey will even work. I purchased the valves after a friend told me the pumps were the same and it would be the single biggest improvement I can make, so I'll need to do some more research before I touch the pump.

Is there anything I missed? I'm hoping to do all that I can with the tranny in the Tahoe. The tahoe should be pushing just over 600 horse when I'm done.
