Re: Need help with 1999 Chevy Lumina
My Trailblazer has been like that for years, but only in the winter.
Cold weather...no reverse until it's warmed up. Forward is fine, though. I've put a hundred thousand miles on it like that.
Far as I can tell, it's a sticky valve in the valve body.
With forward AND reverse problems...I'd be suspecting an air leak into the pump--or a faulty pump.
Time for some pressure testing.

Ten trillion to start with, increasing as needed from there, PLUS compensation for the sickened, and "wrongful death" settlements for the families of those who didn't survive. END trade with Communist China.
