GM Truck Tru-Cool 40K Transmission Cooler Kit

This kit was designed around a problem we see constantly with other transmission cooler setups: the cooler gets mounted directly in the front A-frame area, then later the truck gets a front-mount intercooler, heat exchanger, or other front-end hardware and the entire transmission cooler setup has to be relocated. 

Our setup avoids that problem from the start.

Instead of relying on a large dedicated mounting bracket, the cooler is mounted in a way that keeps the front of the truck open for future intercooler or heat-exchanger installations. That means a cleaner installation now and less rework later. We have been installing coolers this manner for years and works great.

Features:

• Designed for 1999–2013 GM Trucks/SUVs with a 4L60/80e
• Uses Mishimoto MMTC-SP-13N or Derale 13633
  
• Keeps the front A-frame/intercooler area open
• Ideal for trucks that may receive a front-mount intercooler or heat exchanger
• -6AN PTFE crimped and pre-assembled hoses 
• AN fittings for your transmission & transmission cooler ports 
• Black billet aluminum hose separators
• Hardware & riv nuts included
• Excellent upgrade over the small factory auxiliary cooler
• Works well for street trucks, towing applications, & performance builds.

Recommended For:

• 4L60E
  
• 4L80E
• TH400
• Performance street trucks
• Turbocharged trucks
• Towing applications
• Trucks being prepared for future forced-induction upgrades

Depending on availability, the kit will include either a Mishimoto MMTC-SP-13N or Derale 13633 transmission cooler. Proven in 1,500+ HP street applications with zero issues. We build and tune our own transmissions in-house, and we work with high-performance vehicles every day. This is something we’ve tested, used, and know works.

NOTE: If you have a 2008+ 4L80E, please make note we do not provide case fittings for them as they use a different thread pitch than pre 2008 units. Also note that the dropdown selection asks if you have a center lube 4L80e or non center lube. If your outlet fittings are close together you have a non center lube unit, if your outlet fittings are separated by about 15 inches, you have a center (rear) lube 4L80E. This kit is designed to eliminate/bypass the radiator’s internal transmission cooler
