I have a 2015 ram 3500 mega cab that I purchased from the company I work for. They are meticulous on oil changes and maintenance. It is a 6.7 diesel that has been tuned, it has brand new tires, $1100 worth, seat has a small tear in the seam but other than that the interior is excellent. Sunday we were leaving Ogallala and I heard aloud bang and I lost all gears. If I take it in and it's the transmission I'm going to have it repaired but the transmission warranty will not be transferable to the new owner so I have cut the price of the vehicle in half due to the transmission or what I believe is the transmission. The ram has less than 295,000 which is just broke in for a 6.7. I'm either going to sell this truck or I also have a 2014 F350 that only has 95,000 on it and I would take $30,000 for it.
