The tranny has never been serviced. Only 13k miles on the odometer. Right now the interceptor is set at full delay, 25% line pressure. According to Tone 20% to 30% is what the 2001 VXs can take for line pressure because stock pressure is higher than the '00 and '99. The harsh shifts are only occur at low speeds on steep hills where there is a lot of load on the drivetrain... or transition from level to steep at low speeds and with slightly more accelerator input... like heading up hill, add gas, kabam, shift and off we go.
