I have a D6D it has a viboration at about half throttle rev. it up or down it goes away.it is not real bad but a enough that you can feel it,also when you work it when you get it down to that point you can feel it, does it also in netraul, when i touch trans housing it is to hot to touch not working hard just clearing snow out on ditches,any advice thanks.
check u joints in driveshaft first..
K would that also make the tans. run hot, maybe it is normal, torque temp is at about quarter put a new gauge in thought maybe the old one was not reading right but it was, have'nt been in the business very long learning as i go thanks.
Trans makes heat when working, if gauge is not in red it's okay, check the damper on the front of crank. They sometimes come apart. Later Bob
