My transmission is randomly dropping transmission fluid. It goes from no leak to puking under the car. I suspect I have a cracked torque converter. My question is do I try to find a 19 spline converter and have this one rebuilt, or just find a 67 and up Torqueflite with the 24 spline and put behind the engine? Any other thoughts on what could cause it to randomly lose fluid? My transmission knowledge is minimal so any advice would be appreciated.
