Review on Hayden Automotive 678 Rapid-Cool 🔥 Transmission Cooler with Plate and Fin Design by Craig Mcdonald

Fits like a charm, no problem after hauling a 5x8 U-Haul through the southwestern desert this summer. I installed this on a 2nd generation 4 cylinder Toyota Tacoma. I was only towing about 1800 pounds (half the maximum payload of a T2R-FE 4-cylinder) and most told me it probably wasn't absolutely necessary, but I didn't want to risk sending my valuables across the desert by car. Trucks with high mileage. I only used the included foam pads and zip ties for the installation as I didn't have the time or processing tools to make custom mounting brackets. I installed an auxiliary device (not a bypass) and the hose that came with it was *just* long enough to get the job done without kinking or stressing the hoses. Unless you measure and think about it very carefully, it's easy to cut the hose so that another length becomes unusable, forcing you to shell out another $10 for a length of ATF hose. I drained some liquid from the radiator, then played around with the level a bit and found that between the small amount of ATF coming out of the radiator and the capacity the radiator required, I had to add about 400-500ml of ATF for the correct fluid level.
