Transmission Cooler
I want peek performance out of my transmission, so I added a "big" cooler years ago. It worked great in the summer, but was too cold in the winter. So I got a bigger cooler and added an external thermostat. I no longer use the radiators built in trans cooler. Here is the plan:
Mounted the 180F Thermostat (Perma-Cool part #1060) on the right frame rail under the alternator
It has 2 IN & 2 OUT ports. I blocked the cooler IN port.
Hot fluid comes in the E1 port from the transmission
Cold fluid goes out the E2 port to the above trans filter
Hot fluid goes out the C1 port to the trans cooler
Got a bigger cooler now 11 X 11 X 1.5 stacked plate rated to 30,000 GVW. Long part #LPD4590
Spin on filter for cleaner fluid. Perma-Cool part #1791
1st IN port is for fluid from the Thermostat
2nd IN Port is for fluid from the Cooler
1st OUT port send clean-cool fluid back to the transmission
2nd OUT port is for the trans gauge temp sender
I used Thermo-sleeve part #14005 over the lines near the exhaust
