Hi everybody, Andy here with etrailer.com and today we're gonna take a brief look at this Derale single-hose transmission cooler installation kit. This is a complete mounting kit with this high temperature, high pressure hose that will work on most of your transmission coolers that have 5/16 of an inch lines. And this kit includes everything that you see here on the table before me. You're going to get four plastic mounting rods, four foam pads, and four nylon clips for a secure mount. And of course, this four-foot-long OEM spec hose with the 11/32 of an inch inner diameter, four stainless steel hose clamps, and then this Insta-Dapt radiator adapter. This is going to fit most 5/16 of an inch transmission lines, but not all.
In some cases, additional fittings or alterations of the OEM lines or hoses may be required for installation. Well, that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

Complete mounting kit with high-temperature, high-pressure hose will work on most transmission coolers that have 5/16" lines. Thanks for shipping so fast. the response time was impressive!
Below is a picture of the install of my Derale trans cooler (13503) installed in my 2010 Jeep Liberty.
I did not install with the inlet/outlet on the bottom due to thinking that with a plate and fin type cooler air might get trapped in other end. I mounted it horizontal and put the inlet flow on the bottom to assure that any air gets purged. Odd thing about this trans is that there is a bypass valve on the lines that is thermally operated. The flow to the coolers is bypassed until a specific oil temp is reached. Then flow is allowed to go to the cooler(s). This is done because the trans cooler is completely independent of the radiator. There is no thermal exchange between the trans fluid and the engine coolant. With the transmission fluid bypass valve in operation it is not possible to reduce trans temp below a preset level (or nearer ambient temp) because the thermostat valve simply turns off flow to the cooler(s).
In a conventional setup the coolant flows all the time and there is no by-pass. Trans fluid is kept from dropping in temp by the engine coolant which will actually put heat into the trans coolant if the engine coolant is warmer. Chrysler has no thermal exchange with the engine coolant so they thermostatically control flow to keep the trans from operation at a too low temp.
In short, in my vehicle I can’t reduce the trans temp below the thermostat setting, But I can assure that the temp of the trans can never be too hot.
I also mounted the trans cooler on brackets I made. I was uncomfortable pushing the rods thru the radiator and the air conditioning and factory trans cooler. The added mass of the Derale trans cooler may have been a little too much clamped onto the radiator. I tapped into the original hose with a 3/8 double barb fitting and double clamped all connections.
Also below is a exploded parts view showing the by pass valve on the trans lines which directs trans fluid back to the trans and by passes the cooler(s) until the trans gets to a specific temp. It is item #3.
I just want to thank the customer service team at etrailer.com. I got very quick responses with very helpful and educated professional answers within minutes through email. The product selection and prices are great and so is the service team. I didn't get to install my new transmission cooler yet but I can say the kit has every single thing I need including awesome instructions with clear diagrams and everything and the staff was very helpful helping me choose what fittings I needed to avoid having to cut my stock transmission lines. They seem to have all their bases covered. I'll provide pictures after the install. Thanks etrailer staff I appreciate all the info and great products. Keep it up.

Purchased this kit to ensure I had enough spares and hose for a transmission/ steering cooler project. Worked as advertised.
Installed it on a 99 Ford F250 with a diesel, that was having transmission overheating problem when towing a trailer. Fixed the problem.
