15-1/4" Wide x 10" tall x 3/4" deep, reliable, all-aluminum tube-and-fin cooler extends the life and improves overall functioning of your vehicle's transmission.
Features:
Specs:
Note: The Derale Insta-dapt radiator adapter fits most vehicles with 5/16" transmission lines, but not all. In some cases, additional fittings or alteration of the OEM lines or hoses may be required for installation.
Perhaps the simplest type of heat exchanger, the tube-fin effectively cools a variety of automotive systems. The concept is simple: Fluid cools as it travels through the core by transferring heat out to the fins. The fins then provide the surface area necessary for sufficient heat exchange to take place, allowing the heat pulled from the fluid to dissipate into the surrounding air. Quick, easy and effective.

Fast shipping, good price!!! Thank you
Very fast shipping. Everything was there and in pretty decent condition. Would have been perfect, but some fins were bent, though it could have been the delivery company. Definitely recommend
Worked good easy hook up
We're an independent auto and truck repair parts were delivered promptly. Seem to be good quality and fit great on our customers unit thanks..
works well, wouldn't buy one any smaller than this one.
Great product, I’m currently in the middle of the installation.
I was able to mount it but never able to actually install it and hook it up completely.

Is there anything we can do to help with installation?
WOW, My order came fast, I'll be shopping with them again!
easy installation & works great, good v alue.
Everthing as described. From ordering to the home delivery, I was informed every step of the way Good old fashion Americian business! The way it should be done.
You guys set the bar high when doing buisness!
Thanks a million!
Dropped transmission temperature buy 25-30 degrees. I would recommend for anyone trying to help out their tranny.
Fast Shipping Customer Service is Great. They sent me a list of everything I needed.
Easy install. But hoses need to be longer. I had to go to napa to purchase an extra 3 ft. The hose clamps that were included were limited to the amount of tension that were put on them. They would tighten to x amount then just spin. I had to purchase extra hose clamps that actually tightened.
Impressed overall.
I put the transmission cooler on a 2006 ram 2500 it keeps it 30° cooler than the OEM transmission cooler
Works solidly, much better than the optional stock tranny cooler. It doesn't get temps as low as another one I've had, but it doesn't leak like that one either! Always keeps temps within acceptable range, though at the higher end of acceptable when pulling 7-8k in 110*F outside temps and hills. Be prepared to fabricate a mount for it, not a one size fits all kit!
This is a customer service review not a product review.
Leeza J. was very helpful in helping me get everything needed for adding a secondary transmission cooler to my Chevy truck. I ordered 3 different items and the one item was not in stock and I was promised that I would be notified when it arrived. I was notified that the item was in stock 2 days later and I received the package a few days after that. Very good service that impressed me.
Super easy install. With the installation video on Youtube it took out any of the guess work. The hose could stand to be about 3" - 5" longer if you are going to center in the A frame of an older chevy grill (I have an 06 Avalanche. I had to offset to the passenger side to use the supplied hoses) But, you can get a longer hose easy enough. Just ran over the pass and back and no leaks. Looks good so far!
Exactly what I ordered. Quick shipping and all parts needed for installation included! Always easy to find what I need at E-Trailer!
I used this cooler on a 2004 Chevy Silverado. The accessories were not needed because I needed longer hoses and fabricated my own mounting. I think the hose clamps and the hoses could be better quality. The cooler does work very well.
i put this unit in my 2008 NIssan Titan pickup. we are going to take a 9000 mile trip this summer pulling a 27 ft HI Lo camper. The instructions were very generic. specific unit instructions would be very helpful. the grill was difficult to get out until i found a Youtube video for that. the hose provided was to short, so I made a run to the parts store. the unit appears to be well made.

we used the cooler in my 08 Titan. we pulled a 27 ft travel trailer thru 28 states and never had any issues
Hose barbs on the radiator are 0.4 inches, not 0.345. With the added raised portion it's almost 0.5 inches. It's basically impossible to force a 0.335 ID hose over a barb that big. Hopefully I was sent the wrong cooler with the kit, I could only get them on a little past the raised section. The hose will probably split too. You can see how little I was able to push them on in the photo, I bent some fins from slipping while pushing them on. Like I spent 30 minutes trying to force them on with lots of transmission fluid as lubricant.
The hose size is right for the truck. But I'm super glad I didn't order the adapter to the truck radiator if this is the quality of their radiators. Two male to male SS 3/8 inch hose barbs worked perfectly to hook the hoses to the existing line after cutting it.
The hose clamps were almost too big also. They are almost completely tightened down to where the threads stopped. The two in the photo are mine because I needed 6 and the kit only has 4.
It's almost like I was sent partially a kit for 13/32 or 3/8 inch hose. With only the hose being correct.
