Good cooler for cheap
Get different hoses! But it's functional and keeps the temps under 200. Used on my 09 Tahoe

Overall good just cheap hose
Almost really good. It comes with enough hardware and fitting that you’ll need. Just don’t use the hose provided. It busted on me only after 2 hours of driving and had me on the side of the interstate. Replaced with some better stuff. Only reason I’m giving it 4 stars.

Good price lasting quality
Had this trans cooler on my truck for at least 6 months now and it has not given my a sing issue. The install was simple. I installed this on my 99 Silverado for my built 4l60e and have seen my trans temps stay low even after doing hard pulls. Amazing price and quality

Bad supplied rubber hose
Cooler works fine but I would 100% not use the supplied rubber hose. Unless you like paying for a trans rebuild twice.
