Ok, here's what I got. A 1979 c-4 freshly rebuilt and in the truck. Reverse is great. Put in drive and kinda just surges and trembles until I tach it up and finally pulls off. Shifts thru the gears ok but when it gets in drive it will not stay there, drops back to 2nd unless I'm on the gas kinda hard. It feels as though it is slipping in 2nd when it changes and then finally it will level out after a few seconds.
I turned the modulator valve all the way in and I swapped out the valve body to another one that I had. Help!
