i just got the vortec started up today. i just need need to go get a new exhaust put on with dual cats to accomidate the 4 oxygen sensors that the vortec is equipped with. only problem is that i have to rev the engine kind of high just to get moving. i just had the transmission rebuilt and it came from the same donor truck as the engine. is there some chance i wired the lock up torque converter incorrectly? i put in 10 quarts of transmission fluid. after i started the engine and ran it for a while, i checked the dip stick and it was a quart and a half low so i added the appropriate amount. please help.
