Hayden Automotive 512 High Performance Transmission Cooler

Installed 12/16/2020 - First off, install was relatively easy. Took about an hour all together. The fittings that came with it worked fine, I needed some extra hose but luckily I had some laying around. I used my factory cooler location to mount this one so it looks like it’s meant to be there. I can’t speak of how well it’s keeping the transmission cool yet since it’s winter but I will update my review once the weather heats back up this next summer. My reason for installing is because I purchased a used 2005 Silverado 1500 that had a cooler but it leaked.

The 4Runner with over 300k miles then never overheated before even when towing a camper. This past trip I was overlanding and it happened two times where I had to stop and run the heaters and wait for it to cool down. It was while off-roading in Death Valley National Park and through Imogene Pass in Colorado. The cooler seems great quality and was easy to install. The fins are soft so be careful when mounting and you can always bend the fins back to shape if anything. Oh, I also bought the Hayden Automotive 106 Transmission Oil Cooler Hose to route/install everything. I know the V8 4Runners with the towing package come with a transmission cooler from factory, so I am sure it's a great and cheap add-on for anyone off-roading or towing with their 4Runner!

Good product has improved my pull performance a lot more put less stress on the transmission and I have 05 honda accord ex. You will need a longer hose and it was missing 1 plastic fastener.

This item is a good add on for my project car! Had cooling issues with my car, but with this oil cooler along side a cold air intake did the trick! The instructions that came along with it is very detailed and helped out a lot. I still had someone to help me just in case!

Good quality tranny cooler with good quality components. I installed in my 2000 Durango with ease but had to add additional hose to complete my installation with an external oil filter for the tranny fluid. A combination of this cooler, AmsOil synthetic tranny fluid and a Royal Purple filter dropped my temps 30 degrees according to my tranny temperature gauge. Yes the truck does come with a built in cooler incorporated with radiator. But adding more surface area for cooling the oil definitely helps and actually has the engine running cooler too.

The size is ok. Easy to install for any vehicle. I install on my Volkswagen Passat B6 2.0 TFSI Just added 2 couplings from Home Depot and connect it to return and feed transmission pipes. Works good!

Great little cooler easy to install comes with everything you need works great

I installed it in a Trailblazer 05! Worked Great. Was easy to install by mounting it with the hoses facing down not to the side. A must in the Trailblzr and the Envoy in hot climates or towing! Goes in on the drivers side fairly easy. Contact me if you would like details of installation. ([email protected]). DONT buy expensive, this works just fine. UPDATE ! This unit sprung a leak on the way into town left me stranded in Walmart parking lot! Fortunately walmart had hose clamps, tubing and DEX VI trans fluid. I made a bypass laying in the parking lot and was able to get home. When home I wire brushed off the paint at the fitting ends and it revealed a lousy weld at an end that the paint did not reveal. Clearly poor quality control. This unit should still be in service today! I changed to an aluminum unit that has NO welded fittings and expect ti to go forever. NOTE I had their unit properly secured and not in a vibration enviroment.
