Auto trans oil cooler on the track blues....

[Tom Wells]

I'm using a C-6 auto trans on the track. As I learn to go faster, cooling the trans becomes a problem!

I have a 2000-2200 stall converter and have tried several aftermarket coolers without success. The present cooler is a B&M 70297 with a SPAL fan ($200++). At the track day last Saturday, the fan shroud melted stopping the fan. The trans temp shot up, then smoke.....

B&M was no help. They won't RMA just the fan, but need the whole cooler, meaning I need to buy another cooler anyway to use in the meantime, so no real help there.

The trans guy suggested I put the radiator cooler into the circuit after the add-on cooler. The guy at B&M says the radiator cooler should go before the add-on cooler, not after.

Here's the question: how can I cool this trans?

PS: When it is working it is an absolute joy to drive on the track: right=GO, left=STOP
