through the tranny cooler then through the tru-cool. You need the air to water cooler to help with rapid cooling. Without the A2W if the trans ever gets hot it will take a very long time to cool the fluid down, remember, you have 2.5 gallons or more of tranny fluid running through the system. The risk is worth the reward and in all my years I've only heard of one internal cooler leaking.

That is absolutely false, Ive had two trucool 40s on my truck. I was the first to actually get one back in 05 and ran it for 50 or 60K with no problem directly to the cooler and with teh 4200 converter I was running at one point in time I could heat the trans up to almost 200 pulling a small trailer in the the Texas summer and within a couple miles of cruising down the highway it was back to the 140 it stayed at. Ive read of quite a few guys having the end tank on the radiator bust and take out their trans. Why risk it? I see no benefit to running it in the radiator. The one that I installed on another truck and had it going through the radiator didnt heat up noticeably quicker and was a lot more connections with possible leaks. Ive got 4 AN connections in my system, the least amount possible to have the least amount of trouble.Originally Posted by RedHeartbeat
