Why is desirable to use a step down gearbox between an electric motor and a slowly rotating load?
Adding a gearbox to a stepper motor system can improve the motor’s performance by decreasing the load-to-motor inertia ratio, increasing torque to the load, and reducing motor oscillations.

P1778 NISSAN Description The step motor’s 4 aspects of ON/OFF change according to the signal from Transmission Control Module (TCM). As a result, the flow of line pressure to primary pulley is changed and pulley ratio is controlled. This diagnosis item detects when electrical system is OK, but mechanical system is NG.
Is the Trans fluid pressure low on a P1778?
Because I do have a P1778 code. But I also have a P0868 which is “trans fluid pressure low”. I have the V6 model, not sure if that matters? BTW, I live in the counry about 30 miles from the Twin Cities, and I sometimes have to go there. The drivers on the road near and in the cities are much more aggressive drivers than us country folks.
