## Description

Review: Nice finish. Good quality - This cooler is pretty good quality for the price. Comes with a super long 3/8 hose that fits very snuggly around factory metal line barbs. It comes with a hard line adapter so you can just slip on the hose, and comes with a few worm clamps and zip tie mounts. I personally hate zip tie mounts because there is a huge chance of condenser or radiator damage from the cooler vibrating against it but luckily theres plenty of mounting holes and the inner 4 holes are slightly elongated giving more wiggle room when trying to match up holes to bolt into. The barbs on the cooler are also pretty snug but I still prefer using simple spring clamps to hold the hoses in place versus the worm clamp.. Feels more like it was made to be there rather than an aftermarket addition.
Review: Transmission cooler. - This transmission cooler work awesome, Keep the transmission cooler than stock coolers. Looks rad, it's same so it can fit anywhere. Easy to install with easy-to-read instructions. It's well made to last.
