Great investment so far
Completely bypassed radiator and ran straight to this cooler on my 5.3 swapped 94 Blazer. Dropped my operating temp 50°F and I have a 6.5” lift and 37s. Supplied hose seems fine, was just long enough, would’ve been nice to have an extra ft or 2. Wish it used a more standard fitting type. It looks like it uses a 3/8 inverted flare, which in my area and online is hard to find, especially when trying to use my 6an lines. Wasn’t hard to install. No leaks as of right now, looks good and blends in in my case.

Very well made
I have installed many different versions of this cooler and I have to say this mfg is on top of my list the tig welds are clean and precise just one note to all during the hose installation always hold back on the cooler nut while installing the hose

20 degree trans temp difference on Chevy 1500
20 degree difference in trans temp hauling a 4000lb food trailer up the mountain. Well worth it and simple to install.(2011 Chevy 1500) takes a extra half quart of trans fluid for full fill.

Worth checking it out.
Worth the money. Was expecting bad quality for the price. But there were no dings or dents in it. The hardware is a bit flimsy though. I had to add a couple spacers to have it sit over the power steering cooler bolt. And cut and flip the oem trans cooler bracket. But it went well and has been working great the past few days.

Needed more hose
Kit is decent for the price comes with a bunch of different fittings, I only used the 2 going into the cooler. The hose was too short to run both lines to the back of the rad so I just used some compressed air hose I had laying around. Fit well behind the grill of my 06 suburban.

Amazing fitment
Installation was pretty easy used factory bolt holes for the bottom and used 2 heavy duty zip ties and it doesn’t budge. I didn’t want to chop up the factory transmission lines since they’re brand new. Had to add about 1 quart of fluid after the swap. I only had it on for about 2 weeks so far so may update review if something comes up. (2006 Yukon/Tahoe)
