🏎️ Hayden Automotive 514: The Ultimate High Performance Transmission Cooler Review

I bought this because I need a new transmission cooler. It works. But the paint or whatever they put on it sucks. It fell off when I received it.

Great value for money. Now I don't have to worry about coolant ruining the transmission. Anyone who thinks this is a good idea is an idiot. Great for automakers. When coolant and transfluid are mixed, bye-bye transmission.

Works well and easy to install. When installing in a GMC Sierra, you can purchase an adapter so you don't have to change the wiring. The ones that came with it don't fit my model. Be careful not to pull on the ends. I bent mine a bit but it still holds up. Temperatures went from 210 degrees hauling an RV to 165-180. Without camper will be lower. Worth the money, you just have to pay attention to the facilities.

Easy installation. Be sure to purchase nipples to make connecting the new radiator lines to the old ones easy. I used sharpies to plug existing coolant lines to prevent fluid loss. Lost less than half a glass of fluid. I had to add some rubber washers to move the radiator about 1/4 inch to clean it, so have some padding material on hand just in case. That.

My mechanic recommended this tube and fin style transmission cooler, he said it cooled better than a plate cooler. I installed it myself on a 2007 FJ Cruiser in about an hour. I chose this one because the total weight my FJ can tow is 5,000 pounds and this cooler is designed for that. Looks very solid, I installed it in front of the air conditioning condenser. I installed it in line after the oil went through the stock cooler in the radiator and then through the Hayden cooler to keep the return
