Fluid still looks really good, smells fine. I am concerned the car isn't worth the rebuild. Motor still runs great. Did head gaskets 50,000 miles ago. Everything during the teardown was replaced or still looked great. cylinder walls looked great. The car has been an awesome car. But it is also a Michigan car and rust has crept in. I'm having a hard time justifying a trans rebuild on a rusty vehicle with 300,000 on the clock.
