Hey guys, I am looking at buying a 1ton dually soon but have some things I need to know. I want a 3rd gen but dont know what year to look for. I know that some years are better then others and some had tranmission problems. I will be hauling alot with this truck and it will be an auto transmission. So if you could give me some things to look for and what will need to be done to fix it. Say I get an 05 auto that have not the best transmission can I put a newer one on or upgrade? Please let me know. Thanks for the help.
