	The “Getrag” name is commonly used by Fiero owners, while factory service information ~~for 1988 uses~~ the Muncie 282 ~~name~~.		The “Getrag” name is commonly used by Fiero owners, while factory service information may identify the same transmission as the '''Muncie 282''' five-speed manual transaxle.

	Because different GM manual transaxles may share similar layouts or similar casual names, parts should be identified by the actual transmission, application, case features, brackets, cables, RPO code, and related hardware.

Identification

The Getrag 5-speed can be identified by transmission case features, shift cable arrangement, model year, engine application, RPO code, and related mounting hardware.

			A Fiero Getrag 5-speed can often be identified by the location of the reverse-light switch and by the small dipstick on the aft side of the transaxle above the driver-side inboard CV joint.

	Because many Fieros have been modified, repaired, or swapped over time, identification should be based on the actual installed transmission rather than the car's year or trim alone.		Because many Fieros have been modified, repaired, or swapped over time, identification should be based on the actual installed transmission rather than the car's year or trim alone.

			Useful identification checks include:

			* RPO code '''MG2'''
			* V6 application in later Fiero production
			* Five-speed shift pattern
			* Getrag-specific shift cable arrangement
			* Reverse-light switch location
			* Small transmission dipstick near the driver-side inboard CV joint
			* Case features and mounting brackets

 The Fiero Getrag 5-speed was Getrag-designed and Muncie-built. In Fiero owner discussions, it is usually called the Getrag 5-speed to distinguish it from the earlier [[Muncie 4-speed]].

-The Fiero Getrag 5-speed has five forward gears, with fifth gear functioning as an overdrive gear for highway driving.

+The fifth gear is an overdrive gear and helps reduce engine rpm during highway driving compared with the earlier V6 [[Muncie 4-speed]].
-Because transmissions may have been replaced, rebuilt, or swapped, identification should be based on the actual installed unit.
+Because Fieros are often modified, repaired, or transmission-swapped, the actual installed transmission should be identified directly when exact gearing matters.
