It sounds more like a TV cable adjustment or binding TV/ThrottleValve. Maybe other valves binding in ValveBody too. The Corvette Gov should raise the 1-2 shift rpm, but I don't think the Gov is the 2-3 problem. The rubber cooler hose wont affect shift timing or firmness.79280ZX355 said:thanks for the reply guys,..SSedan i have read the contents and understand a little more about the tv system do i need a different cable? i believe its the stock one but it doesnt feel like its binding or catching and ive measured the pull and its about 1 1/8". so i would believe that means im going through all the motions of the tv.? unfortunately with the dual 2.5" exhaust and tight clearances in the trans tunnel, it is difficult to even see what the linkage on the trans is doing, and fixing/adjusting it is near impossle without tearing the exhaust and dropping the trans out. i believe i should get a vette governer and servos as 1st to second gear comes early at like 4500 but third gear doesnt come....till i let off a little 5500 or so is when i get scared because me engine is really winding out. also, part of my trans cooling lines are of rubber hose, would this effect timing of third at all? i will go look again at the lingage and give the tv cable a few tugs/cycles while the cars idleing, then reconnect and go test drive it and see if this changes something. by the way, i have never had a good/solid/strong 2-3 shift at WOT. does this mean it could be set to like 6000+ or something??, because i havent searched that far for it.
