October 5, 2019 - Comment
Long Tru-Cool Max transmission cooler P/N LPD47391. This cooler is rated at 40,000 GVW and measures 8.5″x22.75″x1.25″. This is a stacked plate, low pressure drop unit. This cooler has 3/8″ inverted flare fittings. This is the ultimate cooler for heavy towing and is a must for heavy duty applications, including racing. Heat is what kills an automatic transmission. If you want to extend the life of your transmission and avoid or prolong a costly rebuild, this is very cheap insurance. All parts and instructions are included to mount and plumb this cooler. Advanced cooling protection for car, van, light truck, R.V. and towing applications. When Automatic Transmission Fluid is cold it is viscous. The unique Tru-Cool design allows the colder, thicker ATF to flow more efficiently through two open bypass channels positioned at the top of the cooler. As operating temperatures increase, the ATF becomes hotter and thinner. It’s then directed through the core where it is cooled. Tru-Cool’s highly efficient cooling technology combines improved protection against lube system failure with optimal heat transfer.

Unit was shipped quickly and installed very easily with the included hardware. I don’t…
40-50 degree drop in temps The perfect cooler for a gmt900 truck!Mine is a 2011 SierraTagged the front of it black so it wouldnât stand out along with the brackets. Drilled two holes in the latch bracket brace to hold the top brackets of the brace. That was the only âPermanentâ mod to the truck.Next I used two bolts and cut some tubing to make sleeves to the bottom would stick out a 1/4 inch forward so it wouldnât be sitting on the cross bar preventing the chance of rubbing.For…
Best cooler for the 4L60e while retaining quick connects Recently installed a fully built 4L60e from Tru-Tech Transmissions in alabama(one of the premiere builders of the 4L60 trans). I wanted something that was much larger vs the factory cooler, but also wanted to retain the factory quick connect fittings and not have to run more rubber hose. Found a company that makes the brackets to fit 99 and up Silverados(PayPal [email protected] $65 for brackets, includes shipping). Then all you have to do is order the GM quick connect fittings (2) part…
