41AE/TE AUTOMATIC
TRANSAXLE

DESCRIPTION

The 41TE (Fig. 1) is a four-speed transaxle that is

a conventional hydraulic/mechanical assembly with
an integral differential, and is controlled with adap-
tive electronic controls and monitors. The hydraulic
system of the transaxle consists of the transaxle
fluid, fluid passages, hydraulic valves, and various
line pressure control components. An input clutch
assembly which houses the underdrive, overdrive,
and reverse clutches is used. It also utilizes separate
holding clutches: 2nd/4th gear and Low/Reverse. The
primary mechanical components of the transaxle con-
sist of the following:

• Three multiple disc input clutches

• Two multiple disc holding clutches

• Four hydraulic accumulators

• Two planetary gear sets

• Hydraulic oil pump

• Valve body

• Solenoid/Pressure switch assembly

• Integral differential assembly
Control of the transaxle is accomplished by fully

adaptive electronics. Optimum shift scheduling is
accomplished through continuous real-time sensor
feedback information provided to the Powertrain
Control Module (PCM) or Transmission Control Mod-
ule (TCM).

The PCM/TCM is the heart of the electronic control

system and relies on information from various direct
and indirect inputs (sensors, switches, etc.) to deter-
mine driver demand and vehicle operating condi-
tions. With this information, the PCM/TCM can
calculate and perform timely and quality shifts
through various output or control devices (solenoid
pack, transmission control relay, etc.).

The PCM/TCM also performs certain self-diagnos-

tic functions and provides comprehensive information
(sensor data, DTC’s, etc.) which is helpful in proper
diagnosis and repair. This information can be viewed
with the DRB scan tool.
