Ok after working on it all summer I believe the car is now reliable, running well, and ready for the track. The last project was keeping the transmission cool. I have a PTC 9.5" non locking spragless converter. Issues arose on highway cruises and if a made a run temps would spike and not come back down until I exited the highway and idled. Recently I removed the ac condenser and installed the coolers shown in the attached photo. Cruising temps on a 90* day now stay at 165, rise slightly on a pull, and then come right back down. Fluid exits the trans, enters the bottom of the rad tank, exits at the top, and then enters the bottom cooler. Top line returns to trans. Here's the question/concern: Do you guys think this would give me a back pressure issue causing too high of a pressure in the converter? I've heard that too much pressure will shove the converter forward and take out the crank thrust bearing. Oh, lines in the photo are 3/8 btw. Thanks for any input.
