Anyone put a 4-sp auto or lock-up torque convertor in Early A?
I was wondering if anyone had installed a newer 4-sp auto trans and lock-up torque convertor in their early A and what problems arose; like shift linkage and stuff. I was wondering what would be a good trans to replace the stock one in a '66 Valiant. The goal would be lower RPM during highway cruising and also better fuel economy.
