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.
