My brother and I were out collecting a few HPT log files to send over to Allen when on the way home we pulled up next to a Z3 at a stop light. He wasn’t sure if he wanted to go or not so he hesitated off the line and couldn’t catch me. At the next light he wanted to go. So the light turns green and he beats me across the intersection, hits second then I start to gain on him. This continued at the next two lights also. Made me feel kind of good that he couldn’t get away from me in his little sports car that cost a whole lot more than my truck.

How does that shift kit feel witht he servos and the tune? Can you break them loose in second pretty easily?

No, just a chirp with a nice firm shift. I found this advice some where, I think it was from HitmanX on PerformanceTrucks.net,

"put the stock springs back in and turn the piston around the way it was
A big issue is the accumulator valve for the 1-2, you need to install the softest spring
Stock springs will soften it up a good deal, I DO NOT recommend drilling the 1-2 feedhole out at all. 2-3 go .110 and the 3-4 .125"

I also have the line pressure set at stock. I love the way the trans shifts. Not harsh at all, just nice and firm when you need it to be.

Here's my parts list:

TransGo HD2 shift kit
4L60E 1-2 aluminum accumulator piston (small pin)
4L60E forward clutch aluminum accumulator piston
Corvette servo 4L60E W/ longer pin
Superior 4th gear billet super servo
TransGo separator plate
