My transmission (transgo + vette servo) seems to be shifting too quickly. I put it in tow/haul mode the other day and kind of kicked the trucks ***. If i physically put it in first it will hold, but in drive it wants to shift around 1500-1700, any thoughts?

 

get a diablo sport programer you can adjust each sift point as for as miles per hour and rpm

 

No way I spend money on a diablo sport piece of junk. I'm going to get either a Nelson or an MTI tune once I get ready to put my TC on (two months or so). Nelson does custom tunes for $400 and gives lifetime upgrades, plus any custom tune beats the hell out of a handheld tuner.

My point was that the truck seems to be shiting too early now under normal driving, which I find sort of odd.
