The strength of the 68 comes from the number of frictions it uses over the 45. I have found a way to put even more frictions in the 45 then come in the 68. I also rebuild the pump so that it produces up to 250 psi and modify the valve body. When you put all that together you have a trans that can handle more TQ, that shifts hard, but not harsh.
Very cool. A little over my head but I get the idea lol. Are you able to swap the better gear ratios from the 68/66 into the 45? What's a rough cost for this if you don't mind sharing?
