I have 03 Dodge RAM 3500, 2WD, NV5600 M/T with 266,xxx miles and I pull a 3 car wedge all over. I just put a dual HD disc clutch in it. I have not lost 6th gear and I am going to have someone repair my NV5600. Can't afford a complete rebuild. While I have the transmission out I want to add a few things to it so maybe I can get another year or so out of it. I need a transmission temp gauge installed in it I think. What else would you guys recommend I install to keep my truck pulling for awhile longer?
