transtech105

Being a gm tech.I hope they get rid of the oversized/weighted northstar.awful to work on,expensive to repair(under statement).The most oil leak prone engine we make.The 5.3 in the w cars is a tried and true motor.problem is no more 4t80-e-I heard that it is on it's way out.No other trans is built to handle the high torque requirements.I don't think the 4t65-e in the impala ss will hold up to the power.The af33 in the equinox is bulletproof and is also a possible 7 speed with a new valve body(look it up!).Problem with the 5.3 V-8 is the cadillac customer won't want a pickup motor in their caddy spaceship. Any thoughts.
