This weekend after a 40 minute stint on the track, we saw our transmission temps getting to 247F. That is on a day were it was about 45F ambient and we had the pump and cooler running.
Doing some research, the answers I've heard on safe temperatures are all over. The oil is good to 300F according to the manufacturer and some folks say they run there, but that seems really hot. Most folks say they like to be around 225F. We just rebuilt the transmission and set the R+P to the factory backlash setting of .007", but we're going to open the transmission up and loosen things up a bit. |

Here is a picture of how we did mine and the cooling duct. Under the car I added a baffle in front of the cooler outlet so there would be a low pressure area and help suck the hot air out. The intake is in the front of the right side GT flare in a high pressure area and to help when we were tooling around under caution I installed one of those small boat type bilge vent axial fans AND a mister assembly that was actually a JC Whitney windshield washer kit and a spray nozzle. The little water tank was good for about 15 minutes running and was switched to the fan and I noted once it was turned on, the temp reading (sensor from Jim Patrick in speedo drive hole) would drop approximately 35 degrees in less than a mile! The only issue was cars behind me would see some "steam" coming out the cooler outlet and back way off which turned out to be a very good thing!

I added a fan to the cooler and the high we saw now was 237 on an 80 degree day. Much better.
As a note, we are measuring the temp near the drain, not in the speedo drive area (I plugged that so it doesn't leak). I'm guessing our temps would be hotter than somone reading it back there since the speedo drive so far from the heat source. |
