I'm new to the forum and new really to Diesel trucks. I have a ram 2500 with auto--all stock. I pull a heavy 5th wheel through the hills of the east. I am looking to beef up the transmission to handle the loads. I have searched the web and found about three. Any suggestions on a great one. I(wife and the 5th wheel) would still like smooth shifts, but I want to avoid slippage and better handle the loads. Thanks for any suggestions. I live in Jackson Michigan.
