- Transmissions:

Note: The automatic transmission naming convention is as follows:
- The first character, a number, is the number of forward gears.

- The second character, either the letter F or R, represents front (transaxle) or rear (transmission) wheel drive.

- The next set of characters, a grouping of numbers, represents the design torque capacity of the transmission/transaxle.

- The last character, if used, is one of the following:

- E for electronic shift

- N for non-synchronous shift

- S for synchronous shift

- W for wide ratio

As an example, for the 4F27E transaxle, the number of forward gears is 4, the character F indicates front transaxle, 27 represents 270 ft-lbs of torque capacity and the character E represents an electronic shift.
