Looking for knowledge on automatic transmission fluid. The transmission (powerglide) manufacturer wants ATF, the converter manufacturer wants hydraulic fluid. The car is a top dragster, blown Chevrolet, weighs 2070, runs six teens, approaching 230 mph. I do run a cooler. Have tried Type F, & FTI's newly released fluid, with the same results. Cooked discolored and stinky fluid after a few laps. Clutches, steels, and the band all look fine (20 plus laps on them so far). Transynd, compressor oil, hydraulic oil, dexron 6, type f, seems there are a lot of options available, but at this power level, how much information from the normal super categories, and bracket racers is pertinent. That's why I ask here.
