am @performing motion study to see the motion of vehicle on 35 deg. slope. The required torque is applied, however, the vehicle travel down inspire of increasing the torque value. The gravity  is applied.

The Restitution Coefficient model is selected.

Static friction between tyre & road- 0.6 is considered

Dynamic Friction between tyre & road - 0.4 is considered

Precise contact, & flexible bushings are considered.

Please suggest, any other setting required to be done. I tried using low slope angle, still the  motion is downward.
