    NAG1 Transmission temperature

    I have a 4000 stall protorque converter and was wondering if i can lower the trans temps by making the fans turn on at a lower temperature? Stock tune the HIGH speed comes on at 232 MEDIUM 232 and LOW at 228..... does it make sense to lower these fan turn on temps? thanks!

    I took a second radiator in the transmission oil line. Here you can place a little fan on it.

    But yes, its a good choice to set the fan on temperature lower.
