Description

The TRANS-COOL patent pending fin cooling system is uniquely designed to transmit heat from the inner fins to the outer fins, thus dissipating heat from the '05-'18 Dodge Turbo Diesel G56 manual transmission.

Features include:

  • Holds an additional quart of transmission fluid.
  • Patent-pending aluminum casting 356T6 alloy fins allow for cooling.
  • Bolts securely to any 5-speed or 6-speed Dodge truck transmission.
  • 1/8" drain plugs
Kit includes:

  • (2) TRANS-COOL patent pending aluminum casting 356T6 alloy units
  • (12) PTO bolts and washers
  • (2) PTO gaskets (install new gasket included in system kit)
  • (1) 1/8" pipe plug (temperature gauge port with removable plug).
Dimensions: 6.5"L x 5"W x 4"D

NOTE: Check for possible clearance problems with a larger aftermarket exhaust system before ordering. You will need a minimum of 4 inches of clearance from the base of the PTO mounting surface.

NOTE: 2005 trucks overlapped transmissions during the model run. To determine whether your truck has a NV4500/5600 or G56 transmission so you can order the correct TRANS-COOL, see the shift patterns below.

Great product!
Nov 4, 2019  |  By Adam
This is a well built product but I do think people should know the following before tackling the project: 1. Thin-walled deep sockets help with the machining imperfections where the fins are 2. Even with the factory downpipe, fitment was close and the top bolt on the unit required a long extension with swivel to get a good angle 3. When installing, keep in mind where the 1/8" NPT is (if installing a gauge). I faced mine to the rear of the truck to keep the elements from spraying directly on it All in all a great product, just some food for thought. Thanks again Geno's!

Nice upgrade

This cooler kit is a great addition to the g56. Fitment was excellent. The hardware isn't great. The bolt heads are 17mm and you can barely get a socket on them without hitting the fin casting. The top and bottom bolts I replaced as I could t even fit a thin walled socket on them.
