One thing I should have mentioned. A transmission temp gauge is cheap insurance. I use a mechanical (non electric) water temp gauge for the trans in mine because I have a bunch of them I've accumulated over the years. The best place to get the temp from is the trans pan. I found a good spot on the front of the pan and installed a 1/2 inch NPT bung for the bulb to screw into. Anything over 200 F and you know you need to increase the cooling. I know its off topic but if you do use the converter you have the temp can be an issue. Automatic transmissions fail quickly if they run hot.
