The primary reason the trans temp was so high was due to coolant temp. On a 100 degree day, coolant temps were 220-240. Coolant temps addressed with Koyo radiator, slim shroud changes for greater air flow (primary reason coolant temps were so high), and ducting. For the trans, I have now bypassed the heat exchanger and installed a 180 degree thermostat, so coolant will no longer be part of the temp equation. Rather than purchasing a new set of SSP clutch packs, I'll be purchasing a used trans, having the valve body swapped over, and removing the SSP torque converter. This should be completed early next month in preparation for Auto-X and the cars first track day of the year in March. Car will be running Amsoil signature series synthetic trans fluid as well.
