ACURA M1WA MPWA – ATSG (Automatic Transmission Service Group)
This manual contains tear down and assembly information and some basic electrical diagnostics for the 1992 to 1994 Acura Vigor with the MPWA transaxle and the 1995 and later Acura 2.5 TL with the Ml WA transaxle. Although these wo transaxles are very similar, it is the intention of this manual to illustrate the subtle differences between them.
These two transaxles bare a strong resemblance to the Acura Legend with the MPYA transaxle in as much as they all are inline (north-south) mounted and have removable oil pans. The major difference between the MPYA in the Legend and the MPWA/VT1 WA is the MPYA utilizes a reverse clutch while the MPWA/M1WA utilize a reverse selector and forkassembly. These transaxles contain a low hold clutch which provides a manual low gearshift position and have a complete compliment of electronics to control shift timing, TCC control as well as line pressure rise.
