Tru Cool 47391 40k GVW Transmission Coolers in Stock and Ready to Ship

The 40,000 GVW Tru-Cool 47391 is now in stock and ready to ship from Oregon Performance Transmission.

The Low Pressure Drop, or LPD47391, is by far our most popular cooler for RV towing or heavy duty use.

Due to the Coronavirus shutdowns, there have been many backorders and shortages of this transmission cooler this year. Oregon Performance Transmission has these coolers in stock and ready to ship to you immediately.

This universal fit 40k GVW oil cooler offers the ultimate protection against overheating transmissions, and will install in most full size trucks and SUV applications with excellent results. The 47391 is perfect for heavy towing or hot summer driving, and is a must for heavy duty applications, including racing. Keeping your cooler temperatures low is the first step in avoiding premature, costly repairs, and transmission rebuilds.

Known by multiple names and part numbers, this is the ultimate automatic transmission cooler.

Transmission Failure and Snowplowing

7437758
Snowplow season is upon us for many across the country.  

Plowing and towing at low speeds with an automatic transmission can produce a huge amount of heat, and when it comes to transmission life and longevity, heat is the number one enemy.

If you find yourself needing to rebuild or upgrade your transmission this winter, and you will be plowing or towing, we really recommend our high performance rebuild kits. Our HP kits come with Red lined clutches and Black Kolene steel plates. These clutches are specifically designed to handle 300% more heat than the factory type clutches, and considerably more than the HD high energy clutches. We have HP rebuild kits from Oregon Performance Transmission for the Ford, Chevy, and Dodge transmissions, as well as top quality shift kits to compliment your rebuild.

Our high performance rebuild kits can be found by clicking on the popular transmission application links below.

Chevrolet HP Rebuild Kits
• TH350
• TH400
• 700R4
• 4L60E
• 4L80E

Dodge HP Rebuild Kits
• A904
• A727
• A518, 46rh, 46re
• A618, 47re, 47rh
• 48re

Ford HP Rebuild Kits
• C4
• C6
• AOD
• AODE, 4R70W, 4R75W, 4R70E, 4R75E
• E4OD, 4R100

Even though it’s winter and cold outside, if you are snowplowing or towing, we strongly recommend installing a transmission cooler as well. Our best-selling transmission cooler is the 47391 40,000 GVW Low Pressure Drop cooler from Tru-Cool. This cooler is a work horse and will definitely help keep your transmission temperatures low. You can find it on our website, https://www.oregonperformancetransmission.com under part number LNG-47391.

As always, if you have any questions please do not hesitate to email us at sales@oregonperformancetransmission.com
