The trans generally runs at around 150 and only heats in hot weather and stop and go and then only runs up to maybe 180. If fluid is being pumped at idle the cooler should still be functioning. Thanks a bunch for the input.
Ok, I understand now. With the above info you should be good to go. Keep an eye on those temps though if you beat the car at the track and if the temp heads north of 220-ish deg let the trans rest a while to cool some. The trans's life span will thank you later.
