As mentioned above a better input shaft and 7/8" chain conversion is mandatory, and DONT use a used chain for something like this!!! New chains are not that expensive and I sell the set with a new chain and ready to install sprockets for $295. You are also going to need to purchase a good aftermarket torque converter to survive in that time frame. Your college class books should have the 4T65E in them by now, 12 years ago the 4T60E was in them so I would assume they have updated by now lol. There is a lot more than just buying parts to make these transmission survive and it has a lot to do with HOW they are built.
Cool thanks man I'd definitely appreciate some more info and help when the time comes, cause I'm a total noob when it comes to transmissions lol and I'll definitely need all the help I can get if the lifespan of my trans depends on how well it was built.
