TRANSMISSIONS:
NOTE: The 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 (for example, "27"
represents 270ft./lbs. in the 4F27E 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
^

^
Transaxle: A device consisting of a transmission and axle drive gears assembled in the same case. Front-wheel drive applications.
^
Transmission: A device which selectively increases or decreases the ratio of relative rotation between its input and output shafts. Rear-wheel
drive applications.
^
TR: Transmission Range. The range in which the transmission is operating.
^
TR Sensor: Formerly known as Manual Lever Position Sensor (MLPS). Provides information to the PCM on the transmission range selector
position.
