2 IDENTIFICATION Transaxle model can be identified by vehicle information code plate located on bulkhead in engine compartment. DESCRIPTION Mitsubishi Manual Transaxles KM221, W5M31 and W5M33 are equipped with 3 shift rails, 3 synchronizer assemblies and 3 shafts. Transmission features limited slip AWD using 2 differential assemblies and a viscous coupling. Rear wheel drive consists of transfer assembly directing power to a separate differential at rear axle. Transfer assembly attaches externally to clutch housing, allowing transfer assembly to be serviced as a separate unit. See Fig. 1. NOTE: Mitsubishi transaxle W5MG1 cannot be disassembled. There are 6 external seals, 2 air breather caps, oil filler plug and drain plug that are serviceable. See Fig. 2. If any other parts are defective, transaxle must be replaced as an assembly.

25 Fig. 10: Exploded View Of Transfer Assembly Courtesy of CHRYSLER CORP. BEVEL GEAR BACKLASH ADJUSTMENT 1. On a standard tooth contact pattern, wear is distributed evenly between small end side "A" and large end side "C". Drive side tooth face "B" is side on which force acts when running forward. Coast side tooth face "D" is side on which force acts when reversing. See Fig If contact pattern is at "C" end of "B" and "A" end of "D", driven bevel is too close to drive bevel gear. Use a thicker bevel gear mount adjusting spacer to separate driven bevel gear from drive bevel gear. See Fig If contact pattern is at "C" end of "D" and "A" end of "B", driven bevel gear is too separated from drive bevel gear. Use a thinner driven bevel gear mount adjusting spacer to bring driven bevel gear closer to drive bevel gear. See Fig If correct tooth contact pattern cannot be obtained by changing driven bevel gear mount adjusting spacer, change drive bevel gear preload adjusting spacer and drive bevel gear mount adjusting spacer. See Fig Driven bevel gear mount spacers are available in various sizes " ( mm). Drive bevel gear mount spacers are available in various sizes " ( mm). Drive bevel gear preload spacers are available in various sizes " ( mm). 6. If driven bevel gear height is too small, replace drive bevel gear mount adjusting spacer with spacer one size thicker and replace drive bevel preload adjusting spacer with spacer one size thinner. If driven bevel gear height is too large, replace drive bevel gear mount adjusting spacer with spacer one size thinner and replace drive bevel gear preload adjusting spacer with spacer one size thicker. See Fig Repeat step 6 until tooth contact pattern is equal to or close to standard pattern. If tooth contact pattern cannot be adjusted close to standard pattern, replace drive bevel gear and driven bevel gear as a set and readjust tooth contact.
