acceleration and trans clunk
(AZ - USA)
I have a 1980 Corvette 350/350TH with a Holley 670 secondary vacuum (carb rebuilt) and the problem is it starts fine except putting in reverse. At that point a trans clunk happens but moves along then after accelerating around 30 mph it seems to want to stall until I give it more gas. Then it picks up but the trans sounds like hard banging at this time until acceleration kicks in and trans picks up? This only happens at the 30 mph acceleration point. Any suggestions?
