Hey Guys,
I have a ‘77 c10 400/th350. The transmission is newly rebuilt. The 400 has a pretty aggressive cam. I’ve checked my vacuum hose and fluids.
The transmission won’t shift 1st to 2nd.
I can drive in R or 1st, but it won’t shift into 2nd.
Is it possible I need a power vacuum booster?
The brakes are also a bit soft.
