I do mechanic work on an '03 Dodge w/NV5600 trans, no transmission life. Thinking of adding Tilton pump w/cooler for trans oil. Any input on this??

 

Could add the transmission coolers from Geno Garage. Bolts to the PTO ports. And add about 6qts of Amsoil MTF or Redline MTL for added protection.

I installed a fast cooler to the driver side. Unable to install on the other side due to the 5 inch down pipe. Add a fan cooled CPU heat sink to the fast cooler. This works to keep the temp down. In high 90* weather, towing 16,000 lb, tran temperature stay in the 170 to 180s.

 

I have the Fast Coolers. They work pretty good. In my trans (NV4500) I see around 160-170 loaded on the highway, but that's here in Alaska with temps in the 70's.
