ELECMAN

I bought a th400 tranny from summit 2 years ago.Your lucky I have 200 miles on it.Won't go in to gear,Have to really press on the gas alot to make it move.My mechanic said the tranny is no good losing pressure.I thought these transmisson hold up.I have a 72 cutlass with a 455 engine .20 over mild cam with a 323 rear.Is there anything that an be upgraded in the tranny not to cause this to happen I do play with the dual gate side once in a while.Is there a good place out there that builds good transmisson.Thanks
