'70-'72 C-4 Troubles
'ello
My recently built C-4 is doing some rather Odd things.
When I shift it into D-2 (1st, 2nd & 3rd) & excellerate quickly it acts as if it's jumping back & forth between gears untill I let off the throttle, using a slow to a moderate excelleration it seems to shift properly & it does not always down shift into 1st when I come to a stop. It also seems to shift rather quickly out of 1st when it acts like it is shifting properly.
When I take off in D-1 (2nd & 3rd) it seems to do fine, but if while cruising along I excelerate quickly it seems to jumps back & forth between gears.
Low (1st) is no problem no matter high fast I excellerate even as I Up-shift through the gears manually.
While in Reverse if I excellerate quickly it Shudders untill I back off the throttle. (band adjustment because is related to 1st?)
I've had it back to the tranny mechanic that built it & he's replaced the front modulator valve (i believe that's what he said) & adjusted the bands, It seemed better for a tick, but now acts the same as before or a tick worse.
Any suggestions & helpful intele would be Greatly Appreciated.
