Cheap and long term investment
Every vehicle I own that’s an automatic gets one of these. Easy to install. I personally don’t use the brackets they come with as I have the means to make custom brackets but everything in the box is good quality. The last few times I went with evil brand hoses and connections as I didn’t have enough room

Do not use hose provided with kit
Hoses provided with kit does not withstand fluid pressure, Both Ruptured within 2 hrs of operation. Cooler works good.

Wrong size ports
Looks good but not 1/2" ports. Uses 3/8 hose not 1/2

Small radiator!
This is built like a small radiator and thus works well! Fluid actually flows through it not just tubes like other models.
