SHUDDER OR JERKING IN 7TH AND 8TH GEARS AT 1000 - 1400 RPM. A shudder or slight jerking can be felt when driving with the transmission in 7th or 8th gear and the engine speed is between 1,000 and 1,400 RPM. No related faults are stored and there are not any problems in the chassis systems or with the wheels and tires. This shudder or jerking could begin due to the characteristic power pulses of the N63T engine when it is in VVT mode at low engine loads.
