I’m getting a shudder/stutter, hard hit when accelerating above 30 mph. When I give it throttle above 30 mph and it down shifs the shudder/stutter and hard hit happens. I can let off and accelerate again and then goes away. It is less of a hard hit when in tow haul mode. Just recently installed new CP4 and disaster kit replacement due to cp4 failure.
