When I'm at a dead stop. Floor it. When it shift from 1st to 2nd there's a sort of clunking noise. Only happens from dead stop an 1-2. Everything else shifts fine. Car also pulls more on right side when shifts under hard acc. Tranny was redone and he put a poly mount for the transmission. Any idea what this could be? Didn't seem to be play in drive shaft. All other parts are original. Thanks a bunch! Car 85 z28 5.0 tpi 700r4
