The TV cable is nice and tight at the TB after making the adjustment to spec. I played with the adjustment a little bit fore and aft a few clicks but there was no improvement. Prior to dropping the pan, Im gonna start the car and pull the TV cable 25-30 or so times to see if its stuck. Im mean honestly Im gonna have to drop the pan anyway to replace the TCC solenoid because its not working. The ecm/sol fuse is good but there is no action at the solenoid when I tested it. The early shift prob seems to be pointing at the governor. The guy I got the trans off of said he had the "shift points adjusted" so he very well could have switched governors to a non brf unit. We shall see this weekend when I get her up in the air.
Thanks for the comments on the Vette!!! Its been in our fam for years and I am one lucky guy to inherit that car. Its an original 396 car but we pulled it years ago and put that block in storage. Right now a 502 is resting between the rails followed by a M22 four speed with 4.11s putting those horses to ground. Its a fun car to drive.
