im looking for some help here, i have a turbo car with a built trans (3.52 GMR chain and gears) running a 2700 stall converter from cartuning. i have a external trans cooler and i am still using the factory cooler as well. i am seeing temps up to 220 degree street driving and cant keep it cool. for all you turbo car guys what is your setup to keep the trans cool and what stall and gearing are you using?
second issue is once i am in 4th gear cruising the converter locks up as it should and stays locked from barely any throttle to about 10% throttle. once i hit 10% throttle it starts surging (converter lockup and unlock) until around 20% throttle and then after 20% throttle it will stay locked up until i sink into the throttle hard enough to unlock for power. why am i having this surge issue?
