Hard shift fixed!
I have been chasing down a late, hard 1-2 shift on my '93 corvette. Well today I finally got that fixed! No more chirping 2nd under part throttle! I have adjusted the TV cable last year after getting the car and it made no difference.
The instructions I read never mentioned disconnecting the cruise control at the firewall, I always disconnected cable at the asr servo. Well today I readjusted the TV cable going exactly as the FSM stated. I knew there was a huge difference almost immediately after pulling out of driveway. It shifted to 2nd at roughly 1600 rpm at very light throttle, was a seamless shift too! I have never driven a corvette that didn't even have a shift kit.
Honestly I'm not sure it's right as I don't have a pressure gauge to throw on it. Can anyone confirm shift rpm at normal acceleration? I know it isn't an exact thing, but should let me know if I'm close.
