Transaxle Components & Systems
WARNING: This page is about a different car, the 2003 Buick Regal and 2003 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For transaxle electronic component locations, see Fig 1

The mechanical components of this unit are as follows:
- A torque converter with an Electronically Controlled Capacity Clutch (ECCC).
- A drive link assembly.
- Four multiple disk clutch assemblies: Input, 2nd, 3rd and 4th.
- Three friction bands: Forward band, 2-1 band and Reverse band.
- Two planetary gear sets: Input and Reaction.
- Three one-way clutches: one roller clutch (1-2 support) and two sprag clutches (3rd and Input).
- A final drive and differential assembly.
- One control valve assembly.
- One vane type oil pump.
The electrical components of this unit are as follows:
- Two shift solenoid valves: 1-2 and 2-3.
- A Torque Converter Clutch Pulse Width Modulation (TCC PWM) solenoid valve.
- A Pressure Control (PC) solenoid valve.
- A Transmission Fluid Temperature (TFT) sensor.
- Two speed sensors: input shaft and vehicle speed sensors.
- A Transmission Fluid Pressure (TFP) manual valve position switch.
- A transaxle range switch.
- A transaxle internal wiring harness assembly.
