I recently bought this C6 Corvette (Edelbrock E-force supercharger, billy boat headers) about 2 months ago in a no-run condition fitted with a new cam, and head into it. It ran well, I've noticed it doesn't go into 2nd gear and skips into third. Thinking it was a mechanical problem I data logged the condition. When coming to a right turn I did notice it started in 2nd gear, but after revving it out to 4500 rpm it ultimately skipped 3rd gear and went into 4th gear (I have to let go of the throttle for it to shift at all.) Now here's the question, will this be a mechanical or an electrical problem? since I've seen all the gears go in I'm thinking it might be a servo pin problem since the clearances might be off. Or maybe the transmission is just going out. I'll post the data log and see if anyone can point me in the right direction. I do have an upgraded Corvette servo with a longer pin ready to go in but am hesitant to do so in case someone else on here has had the same problem.
Thanks,
Jeff.
