Got this kit yesterday and installed it 12/23/23. Everything was fine... except that with my vehicle the hoses need too be swapped. Refer to the online directions. Another pro tip... Orings don't stay on the fitting, they go under the washers (patience or paying attention might have helped the first time). There are a couple of good YouTube videos if you get stuck. Other than that the kit was very good, I had zero issues with the fittings, just take your time.

Love the kit my recommendation for it would be to buy a new trans cooler and the job will go super smoothly

Everything I expected. You get what you pay for. Quality product that is overbuilt, and will last longer than the truck.
