Well after a great cam install, ran into a snag. Transmission wont go into overdrive at all. We installed superior intermediate billet servo +35% over corvette. (1-2) and the Maximum Overdrive billet Servo. It has 50% more holding power than the stock overdrive servo. We had to have a superior tech walk us through the install, and it installed fine. They look a lot different than the stock setup. the 1-2, and 2,3 shift great. Just od doesnt ever shift. 70mph is like 3400rpms.
Yall think its a install problem? Or a tune issue? Just wanting to get opinions until monday when Nelsons opens up. I was hopeing it just needs a tune adjustment. My previous tune had upped firmness, and tm %80 removed I think. I dunno but messing up the 4th servo install is kinda hard. It just goes inside the cover. Help please!!!
