SPEED SENSOR - OUTPUT
DESCRIPTION
The Output Speed Sensor is a two-wire magnetic
pickup device that generates an AC signal as rotation
occurs. It is threaded into the transaxle case (Fig.
287), sealed with an o-ring (Fig. 288), and is consid-
ered a primary input to the Powetrain/Transmission
Control Module.
OPERATION
The Output Speed Sensor provides information on
how fast the output shaft is rotating. As the rear
planetary carrier park pawl lugs pass by the sensor
coil (Fig. 289), an AC voltage is generated and sent to
the PCM/TCM. The PCM/TCM interprets this infor-
mation as output shaft rpm.
The PCM/TCM compares the input and output
speed signals to determine the following: ² Transmission gear ratio
² Speed ratio error detection
² CVI calculation
VEHICLE SPEED SIGNAL
The vehicle speed signal is taken from the Output
Speed Sensor. The PCM converts this signal into a
pulse per mile signal and sends the vehicle speed
message across the communication bus to the BCM.
The BCM sends this signal to the Instrument Cluster
to display vehicle speed to the driver. The vehicle
speed signal pulse is roughly 8000 pulses per mile.

(Fig. 310). NOTE: To ease removal of the valve body, turn the
manual valve lever fully clockwise to low or first
gear.
(9) Remove park rod rollers from guide bracket
and remove valve body from transaxle (Fig. 311) (Fig.
312).
CAUTION: The valve body manual shaft pilot may
distort and bind the manual valve if the valve body
is mishandled or dropped.

CAUTION: Do not handle the valve body assembly
from the manual valve. Damage can result.(9) Using a screwdriver, push park rod rollers
away from guide bracket (Fig. 6) and remove valve
body assembly (Fig. 7).
NOTE: Depending on engine application, some
accumulators will have two springs and others will
have one spring. The springs are color-coded
according to application and year. When disassem-
bling, mark accumulator spring location to ease
assembly. (10) Remove underdrive and overdrive accumula-
tors (Fig. 8).
(11) Remove low/reverse accumulator snap ring
(Fig. 9).

(59) Using a suitable punch , drive out park guide
bracket pivot shaft plug (Fig. 62).
(60) Using ordinary pliers, remove pivot shaft and
guide bracket assembly (Fig. 63). (61) Inspect guide bracket components for exces-
sive wear and replace if necessary (Fig. 64).
NOTE: The Low/Reverse Clutch Piston has bonded
seals which are not individually serviceable. Seal
replacement requires replacement of the piston
assembly.
