What is the difference between Overdrive and Hold?


Hold

Hold is a switch that keeps the transmission in a certain gear. Mazda recommends using the hold mode when starting from a stop on slippery surfaces, when driving up steep inclines, or for braking assistance on when driving downhill.

The normal shift pattern with Hold off is:

D: 1, 2, 3, 4
S: 1, 2, 3
L: 1, 2

With Hold engaged, the shift pattern becomes:

D: 2 (briefly), 3
S: 2
L: 1



Overdrive

Overdrive is on a transmission in which the highest gear ratio is less than a one-to-one ratio. This means the drive shaft turns faster than the engine crankshaft. The overdrive feature saves fuel and because the engine runs slower, engine wear and noise are reduced. Unfortunately under some driving conditions the transmission will tend to shift more, which puts additional wear on the transmission.

The normal shift pattern with Overdrive on is:

D: 1, 2, 3, 4
2: 2
1: 1

With Overdrive off, the shift pattern becomes:

D: 1, 2, 3
2: 2
1: 1
