System Description and Functional Operation
System Description and Functional OperationThe alpha-numeric code used to identify the
42LE Transaxle can be broken down as follows:
- 4 = Four speed
- L = Longitudinal (mounted longitude)
- 2 = Torque capacity
- E = Electronically controlled
The hydraulic/mechanical part of the transaxle consists of the following:
- Three multiple disc input clutches
- Two multiple disc grounded clutches
- Four hydraulic accumulators
- Two planetary gear sets
- Hydraulic pump
- Valve body
- Solenoid pack
The hydraulics of the transaxle provide shift select functions, main line pressure regulation, torque converter (TCC) and cooler flow control.
The electronics of the transaxle consist of various input sensors and output devices which, when working in unison with the hydraulic/mechanical portion of the system, provide for optimum shifting, adaptive controls and information about system Diagnostic Trouble Codes that may occur.
