Transaxle Components & Systems

WARNING: This page is about a different car, the 2002 Buick Regal, 2002 Buick Century, 2001 Buick Regal, and 2001 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For transaxle electronic component locations, see Figure .

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.
