Franchise agreements. Franchisors and franchisees are required to comply with the Franchising Code of Conduct. The Code applies to conduct occurring on or after 1 January 2015 in relation to all franchise agreements entered into, transferred, renewed or extended on or after 1 October 1998.
Generally speaking, overdrive is the highest gear in the transmission. Overdrive allows the engine to operate at a lower RPM for a given road speed. This allows the vehicle to achieve better fuel efficiency, and often quieter operation on the highway.
Overfilling an automatic transmission causes the fluid to foam, leading to erratic gear shifting, oil starvation and transmission damage. Overfilling a manual transmission causes the fluid to leak from the vent and the gear trains to slow down when the clutch is depressed, leading to gear shifting problems.
