Description
The DP0 automatic transaxle is a four-speed transaxle that is a conventional hydraulic/mechanical transaxle assem-
bly with an integral differential, and is controlled with adaptive electronic controls and monitors. The hydraulic system
of the transaxle consists of the transaxle fluid, fluid passages, hydraulic valves, fluid pump, and various line pressure
control components.
The Transaxle Control Module (TCM) is the heart of the electronic control system and relies on information from
various direct and indirect inputs (sensors, switches, etc.) to determine driver demand and vehicle operating condi-
tions. With this information, the ECM/TCM can calculate and perform timely and quality shifts through various output
or control devices.
The TCM also performs certain self-diagnostic functions and provides comprehensive information (sensor data,
DTCs, etc.) which is helpful in proper diagnosis and repair. This information can be viewed with the X-431 scan tool.

Description
The QR523 five-speed transaxle is a constant-mesh manual transaxle that is synchronized in all gear ranges, includ-
ing reverse.
The transaxle consists of three major sub-assemblies:
•Input shaft
• Output shaft
• Differential transaxle assembly
The transaxle shift system consists of the following components:
• Mechanical shift cover
• Shift rails
• Shift forks

The following are the details of the manual transaxle:
Neutral
Engine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. Since no synchro-
nizers are engaged on either the input or output shafts, power is not transmitted to the output shafts, power is not
transmitted to the output shaft and the differential does not turn.
1st Gear
Engine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft first
gear is integral to the input shaft, and is in constant mesh with the intermediate shaft first speed gear. Because of
this constant mesh, the output shaft first speed gear freewheels until first gear is selected. As the gearshift lever is
moved to the first gear position, the 1-2 fork moves the 1-2 synchronizer sleeve towards first gear on the output
shaft. The synchronizer sleeve engages the first gear clutch teeth, engaging the gear to the output shaft, and allow-
ing power to transmit through the output shaft to the differential.
2nd Gear
Engine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft
second gear is integral to the input shaft, and is in constant mesh with the output shaft second speed gear. Because
of this constant mesh, the output shaft second speed gear freewheels until second gear is selected. As the gearshift
lever is moved to the second gear position, the 1-2 fork moves the 1-2 synchronizer sleeve towards second gear on
the output shaft. The synchronizer sleeve engages the second gear clutch teeth, engaging the gear to the output
shaft, and allowing power to transmit through the output shaft to the differential.
3rd Gear
Engine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft third
speed gear is in constant mesh with the output shaft 3-4 cluster gear which is fixed to the output shaft. Because of
this constant mesh, the input shaft third speed gear freewheels until third gear is selected. As the gearshift lever is
moved to the third gear position, the 3-4 fork moves the 3-4 synchronizer sleeve towards third gear on the input
shaft. The synchronizer sleeve engages the third gear clutch teeth, engaging the gear to the input shaft, and allowing
power to transmit through the output shaft to the differential.
4th Gear
Engine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft fourth
speed gear is in constant mesh with the output shaft 3-4 cluster gear which is fixed to the output shaft. Because of
this constant mesh, the input shaft fourth speed gear freewheels until fourth gear is selected. As the gearshift lever
is moved to the fourth gear position, the 3-4 fork moves the 3-4 synchronizer sleeve towards fourth gear on the input
shaft. The synchronizer sleeve engages the fourth gear clutch teeth, engaging the gear to the input shaft, and allow-
ing power to transmit through the output shaft to the differential.
5th Gear
Engine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft fifth
speed gear is pressed on to the input shaft, and is in constant mesh with the output shaft fifth speed gear. Because
of this constant mesh, the output shaft fifth speed gear freewheels until fifth gear is selected. As the gearshift lever
is moved to the fifth gear position, the 5-R fork moves the 5-R synchronizer sleeve towards the output shaft fifth
speed gear. The synchronizer sleeve engages the fifth gear clutch teeth, engaging the gear to the input shaft, and
allowing power to transmit through the output shaft to the differential.
Reverse Gear
Engine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft
reverse gear is integral to the input shaft, and is in constant mesh with the reverse idler gear. The reverse idler gear,
which reverses the rotation of the output shaft, is in constant mesh with the output shaft reverse gear. Because of
this constant mesh, the output shaft reverse gear freewheels until reverse gear is selected. As the gearshift lever is
moved to the reverse gear position, the 5-R fork moves the 5-R synchronizer sleeve towards the output shaft reverse
gear. The synchronizer sleeve engages the reverse gear clutch teeth, engaging the gear to the output shaft, and
allowing power to transmit through the output shaft to the differential.
