I am seventeen years old i have a 2001 f250 diesel. The other night my friend drove my truck and got it stuck in a field and left about a foot an ahalf ruts. Against my wishes he rocked the truck back and forth from drive to reverse trying to get it out. Now when i put the truck in reverse the truck starts making a bogging noise and then will die and or will start off slow. I have a feeling it is my tranny if this is the case i will take it out and rebuild it but if anyone has had a similar experience or if you know what i should do please help this is my baby i use this truck for everything its my work truck and party truck please help.
