Red face Carb vacum for tranny problems.

I recentley put a 1in spacer on my 350. The engine is running really good, but the transmission does not want to shift that good. The only thing I can think is wrong is that the carb is not pulling enough vacum on the line that runs to the transmission. The transmission still shifts but it wants to stick in a low gear causing the rpms to run super high and the engine to scream. It sounds pretty cool but its going to tear up my tranny. Does anyone know how i can fix this problem.

Have you checked to make sure the trans linkage at the carb is adjusted correctly. You didn't stated what trans you have. Does your vacuum line run off the carb or the intake? Need more info.

You need to make sure you have the tranny vac. line ran to manifold vac. It sounds like you have it hooked to ported vac. I always run the trans line to a vac port coming off the manifold not the carb.
