Better coolant

Great quality. Seams like it will last a while.

Works great on our work van for towing. Will be installing one on my G/F Envoy for towing our camper.

As other posters have noted, the 5/16" hose included with this cooler is borderline too small. Derale includes 5/16" trans hose, but it's a real chore to get it on the transmission cooler nipples. IMO, they should have included 3/8" host instead. It took a couple minutes to get the hoses on (even after lubricating the connections with trans fluid) and I ended up deciding that I wasn't comfortable with the stretched out rubber. I ended up going down to the local auto parts store and buying 5 feet of 3/8" trans hose and it worked perfectly with the included hose clamps.As for my specific application, I installed cooler on a 2008 Silverado 1500 and it seems to be working just fine. I couldn't end up bolting the cooler down due to being oversized for brackets in front of AC condenser. I ended up using 8 heavy duty zip ties and was able to secure it very well. If you installing on a GM product, you'll need a Hayden Coolers 397 transmission fitting to adapt to GMs fittings (the fitting included with the kit don't work) so you should budget another $7-9 for the fitting adapter and another $8-10 for new hoses.Would have been 5 stars if Derale included 3/8" hose which actually fit their own cooler and did require you to stretch out the included 5/16" hose.

Installed this Derale (part #13504) external trans cooler on my '01 Chevy truck and '01 Chevy Tahoe. It fit great with minimal modification. I've created a step-by-step video to show the install process that I used. Search YouTube for "Trans Cooler Install, '01 Chevy Truck 1500".This cooler has been working great for us and will make the 4l60e trans last much longer here in the southern US States. Where we live in Texas, it's common to see 4L60E transmissions go out by 100k miles because of the extreme heat we have. So if you live in a hot climate area and tow or drive you vehicle hard, a cooler like this is a must. It will save your trans and the headache of paying $1200 to have it rebuilt.
