I have an '07 DRW 3500 5. 9 2wd with the G56. Truck is totally stock with 490,000 miles on the transmission. It is now starting to make noises in 2nd and sometimes 3rd gear when accelerating. I suppose I will be replacing it soon. My question is what to do? Low mileage used, have someone rebuild mine, buy a Dodge factory reman or an ATS unit? My buddy who has the same transmission had Standard do his and had 2 failures in very low miles (1500 and 20,000). He then got another rebuilt unit from another rebuilder and it is going down at about 25,000 miles. His truck was used with 90,000 miles when he purchased it and the transmission he took out at 560,000 miles was a Dodge Mopar reman. Anyone have any suggestions? We make a living with these trucks and want it right, so not concerned with being a cheapskate. Oh, I have ran the factory DMF and Mopar clutches the entire time, getting 250,000 miles per with no problems. I'm thinking Dodge or ATS. You guys steer me in the right direction.
