Manual – the driver has to perform each gear change using a manually operated clutch
Automatic – once placed in drive (or any other 'automatic' selector position), it automatically selects the gear ratio dependent on engine speed and load
Basically there are two types of engine installation:
In the longitudinal direction, the gearbox is usually designed separately from the final drive (including the differential). The transaxle configuration combines the gearbox and final drive in one housing and is only built in individual cases
In the transverse direction, the gearbox and final drive are very often combined in one housing due to the much more restricted space available
Every type of transmission occurs in every type of installation.
The C-series is a manual transmission for transverse engine applications, front engine front wheel drive and mid-engine rear wheel drive applications, built by Aisin AI, as well in the Elise and Exige.
The G-series is a 4- and 5-speed manual transmission for rear wheel drive and all wheel drive applications, built by Aisin AI and Toyota Autoparts Philippines.
The L-series are 4- and 5-speed manual transmissions for rear wheel drive cars and trucks. Not to be confused with the L-series (HSD) hybrid transmissions.
The P-series is a 5-speed manual transmission for rear wheel drive cars with Porsche-type synchronizers. Not to be confused with the P-series (HSD) hybrid transmissions.
