I just rediscovered that I have a 700R4 trans buried in the shop. It came out of an 84 chevy 3/4 ton with a 6.2 diesel motor and it looks like its been rebuilt. I want to install it in my truck to replace the sm465 I've been running, but I dont know if it will survive. What has been your experiences with this transmission. My truck has 550-600 hp at the flywheel and the rig weighs 5226 lbs. Will this thing work or do I need a th400? thanks
