Description:This is the ultimate cooler for heavy towing and is a must for heavy duty applications, including racing, towing, and hauling. Heat is what kills an automatic transmission. If you want to extend the life of your transmission and avoid a premature, costly rebuild, this is very cheap insurance. Built to OEM specifications, this cooler is the best choice for your truck, van, RV, or car.How It Work:Automatic transmission fluid (ATF) is more viscous when it’s colder. THE Low-Pressure Drop (LPD) Transmission coolers have a unique cold-weather passive bypass that allows the thicker ATF to flow more efficiently through the cooler at the top of the system.

How It Work:
Automatic transmission fluid (ATF) is more viscous when it’s colder. THE Low-Pressure Drop (LPD) Transmission coolers have a unique cold-weather passive bypass that allows the thicker ATF to flow more efficiently through the cooler at the top of the system.
As operating temperatures increase, the ATF heats up and becomes thinner. The COOLER system then directs the ATF through the core, where it is cooled.
You get optimal heat transfer and improved protection against lube system OF SIZE..........................8 1/2" X 22" X 1 1/4"
GVW SIZE........................3/8" INVERTED FLARE HEX
COOLING PLATE TYPE.....................MAX FIN & QUALITY- Reliable, Durable Brazed Aluminum Construction. Precise fin Spacing
FUNCTION- When an Auxiliary Transmission Oil Cooler is Required for your Vehicle, Delivers Optimal Protection
PRINCIPLE - The primary purpose of a transmission cooler is to keep the hydraulic fluid inside the transmission cool. A transmission cooler can help your transmission last longer
COMPATIBILITY AND SIZE - LPD47391 Advanced Cooling Protection for Car, Van, Light Truck, R.V. and Towing Applications. The size of parts in the product is on the detail page below
Symptoms of a Bad Transmission Cooler
1. Increased Temperature
2. Strange Transmission Noises
3. Poor Performance. A good transmission cooler can prevent the engine oil from overheating and causing deterioration of transmission performance and even damage to the transmission.
Excellent Performance Transmission cooler features a highly durable aluminum material with precise fin spacing to ensure efficient airflow through the body for maximum cooling. The heat sink with excellent thermal conductivity increases the heat dissipation area and accelerates heat dissipation.With how great this cooler is when it comes to keeping temperatures in a safe range.
