1974 Dodge Dart Sport rebuild

I forgot to add....your transmission is probably a later 998 or 999 lockup version of a 904. Nothing wrong with that or any extra wiring to do. The torque converter locks up automatically thru hydraulic pressure. If you haven't already bolted the trans to the motor, lay your flex plate against the converter and make all 4 holes line up. Then mark one hole on the flex plate (doesn't matter which one) and also the converter at that same hole. When you put the flex plate to converter bolts in, line the 2 marks up and put that bolt in first. I usually just hit the flex plate and converter with a shot of spray paint to mark it. The converter will only line up one way, so that is how to get it right the first time without having to rotate it and hope it lines up on the next try...lol. Hope that makes sense and hope it helps.
