Hey Boys,
I have an 05 Columbia w/860k and she runs pretty good. Lately I've noticed she gets thumpy in 10th gear w/40 + in the can.
Lower gears in a pull its not really noticeable, just when u load the engine on hill before i have to downshift.
1. Is this a drivetrain thg or harm balancer/engine related issue.
Thx in advance. T
