Low Pressure Drop Transmission Oil Cooler Kit Max 40K GVW Replaces# LPD47391, 47391 - Silver

This product made a tremendous difference. On my 08 Silverado WT, the transmission temp would climb past 220 degrees during normal driving, which is too high for me. With this cooler installed it's new normal temp is around 160, which is where I'd like it to stay. With a small trailer hauling my golf cart, it runs around 185-190 on the highway. Good product!

I tried a larger pan plus 2 coolers and still my transmission would hit 235 when pulling our camper and that was on flat ground. I removed the 2 coolers and installed this cooler and the transmission hasn't gotten over 185 and that was pulling the same camper on very hilly roads. What an awesome cooler.

Dose what it suppose to

Ine came bent but no leaking stilled used highly recommended

It’s only been in for a few days, but the temps are about 30-40 degrees F lower than with the stock cooler. I’m nervous about the structural integrity, as it seems like really soft metal. Time will tell. I used the factory hose with some minor modifications and only used the supplied hose to guard the factory hose in its new location.

Supplied rubber hose blew less than 50 miles of installing, while going down interstate normal speed, return side. Sent message, no reply. $130 towing fee, $50 transmission fluid. Do not use this hose. It would be nice to have the feed through zipties as well. But, temp dropped 40 degrees overall when it was running. Good/Bad, you decide.

First off the cooler works great. Was pulling a 7klbs RV with suburban over afton mt on 64 in VA and hitting 250* trans temp. Regular cruising around 220*. After cooler install cruise temps 170-180, 200 peak.The problem was hardware supplied. The cooler has 3/8 NPT inlets. They supplied 1/4” NPT fittings, so I had to drive an hour to the parts store to get the right stuff.

I highly recommend don’t use the clamps, send w this cooler, two broken at installation, buy better ones, expend little more money, the clamps they send are a joke, don’t risk your car.

Box was fine but cooler is damaged
