    Works great.
    Just what the truck needed when towing. Cools the transmission down. Installation was easy.

    Appears to be a really good cooler (REVISED/UPDATED)
    Appears light weight but it does the job well. On my Chevy Avalanche 2500 with an 8.1L Vortex V8, during 35+ mph my trans temp reads 150 degrees. Below 35 when the temp reaches 160 degrees the 10″ fan I put in front of it kicks on and drops the temp back to 150. The proof will be when pulling my 32′ 6000lbs travel trailer later in the year. The old trans cooler is less than half the size and on hard hill pulls I would see up to 215 degrees. Ouch!The Hayden 679 “just” fits. I had to create my own brackets for mounting. The trans oil lines on the 2500 with an 8.1L engine come up through just left and right of center under the radiator. The Hayden connectors are almost perfectly in line with the trans lines. Simply cut the lines, remove the old trans cooler, flair the tubes, and use 3 to 4 inches of included hose to connect the lines. The nice part about this is it is impossible for the hose to come off. The hoses can’t go down. There’s a bend in both trans lines that won’t allow this. The hoses can’t go up, the cooler is in the way. If the cooler performs well pulling my travel trailer then I’ll be really pleased.Adding some praise to this transmission oil cooler. I was looking forward to towing my travel trailer into Colorado this year. Unfortunately because of not just one but two idiots, my Avalanche was taken out of commission. What’s this got to do with this cooler? The second accident was a front end collision where a driver tried to make an off ramp, hit the guard rail and bounced his car at a dead stop in front of my 8,000 Lbs Avalanche doing 45 on the off ramp. Bam! Major front end damage, and yet this oil cooler is still in one piece, bent, but no leaks at all. I’d almost use it again, but instead I just ordered a new one to replace this bent but still functional one. Tough little sucker.

    Nice
    It was a debate between two. I picked this one and don’t regret it. Works like a charm. Transmission much cooler in this Florida heat.

    This transmission cooler is awesome 👌 I just wish it would have fit where I needed it! Sad that it didn’t work for me! I will purchase a smaller one soon! Hayden hands down! Is the best!!!!…

    Good value
    Good value for price but I would NOT use it on a truck pulling a heavy trailer!!!If that’s what you’re looking for you need a much bigger, thicker, heavier one then this.I put this on ’13 acura tl with a12″ fan and it works great for it but definitely not for towing.

  7. Jason waters

    Easy install
    Fit great and was a very simple install on 1998 4Runner

    Transmission cooler
    Added this to my 2008 chevy half ton. Dropped the temperature by almost 30 degrees pulling my Rv.Highly recommend this one for an upgrade
