Rebuilding a 2001 1500 with 46re, and the trans cooler lines do not run into the radiator, but the radiator has fittings for it. I looked at several previous years at the salvage yard and noticed the cooler lines go into the radiator first and then the cooler. Anyone that can shed some light on this would be a great help.
I can purchase lines for an older gen 2 truck and run it into the radiator first and then the cooler- think its a good idea or stick with the way it is? Also I thought the tranny fluid had to be a certain temp before it goes into overdrive- I live in a northern climate.
