35. Remove the front carrier/rear annulus (2) and #6
needle bearing (1).
36. Remove the rear sun gear (2) and #7 needle
bearing (1).
NOTE: The number seven needle bearing (1) has
three antireversal tabs and is common with the
number five and number two position. The orien-
tation should allow the bearing to seat flat against
the rear sun gear. A small amount of petrolatum
can be used to hold the bearing to the rear sun
gear.

34.Measure 2/4 clutch clearance:Set up dial indi-
cator (1) as shown. Press down clutch pack with
finger and zero dial indicator. Record measure-
ment in four (4) places and take average reading.
The 2/4 clutch pack clearance is 0.76 to 2.64
mm (0.030 to 0.104 inch).If not within specifica-
tions, the clutch is not assembled properly or is
excessively worn.There is no adjustment for
the 2/4 clutch clearance.
35. Install the #7 needle bearing (1) to the rear sun
gear (2).The number 7 needle bearing has
three antireversal tabs and is common with
the number 5 and number 2 position. The ori-
entation should allow the bearing to seat flat
against the rear sun gear. A small amount of
petrolatum can be used to hold the bearing to
the rear sun gear.
36. Install rear sun gear (2) and #7 needle bearing
(1).

42. Install the number 3 thrust washer (1) to the
underdrive shaft assembly (2). Be sure five tabs
are seated properly.
43. Install the number 3 thrust plate (3) to the bottom
of the overdrive shaft assembly (1). Retain with
petrolatum or transmission assembly gel (2).
44. Install the overdrive shaft assembly (1).

19. Install the number 12 thrust bearing (3) over the
output shaft and against the rear planetary gear
set. The flat side of the bearing goes toward the
planetary gearset and the raised tabs on the inner
race should face the rear of the transmission.
20. Install the reverse/input planetary assembly (1)
through the low/reverse clutch assembly.
21. Install the park sprag gear (1) onto the output
shaft.
22. Install the snap-ring (1) to hold the park sprag
onto the output shaft.

31. Install the number 6 thrust bearing (7) against the output shaft selective thrust plate (6) with the flat side against
the thrust plate and the raised tabs on the inner race facing the front of thetransmission.
32. Install the reaction annulus (8) into the reaction planetary gear set.
33. Install the 4C retainer/bulkhead (2) into the trans-
mission case. Make sure that the oil feed holes
are pointing toward the valve body area. Rotate
the reaction annulus during the installation of the
4C retainer/bulkhead to ease installation.
34. Install the 4C retainer/bulkhead tapered snap-ring
(1) into the transmission case with the taper
toward the front of the case. Make sure that the
open ends of the snap-ring are located in the
case opening toward the valve body area.
35. Air check the 2C and 4C clutch operation.

OPERATION
Compensation is required for performance variations of two of the input devices. Though the slope of the transfer
functions is tightly controlled, offset may vary due to various environmental factors or manufacturing tolerances.
The pressure transducer is affected by barometric pressure as well as temperature. Calibration of the zero pressure
offset is required to compensate for shifting output due to these factors.
Normal calibration will be performed when sump temperature is above 50 degrees F, or in the absence of sump
temperature data, after the first 10 minutes of vehicle operation. Calibration of the pressure transducer offset occurs
each time the output shaft speed falls below 200 RPM. Calibration shall be repeated each 3 seconds the output
shaft speed is below 200 RPM. A 0.5 second pulse of 95% duty cycle is applied to the governor pressure solenoid
valve and the transducer output is read during this pulse. Averaging of thetransducer signal isnecessary to reject
electrical noise.
Under cold conditions (below 50 degrees F sump), the governor pressure solenoid valve response may be too slow
to guarantee 0 psi during the 0.5 second calibration pulse. Calibration pulses are continued during this period, how-
ever the transducer output valves are discarded. Transducer offset must be read at key-on, under conditions which
promote a stable reading. This value is retained and becomes the offset during the
coldperiod of operation.
GOVERNOR PRESSURE SOLENOID VALVE
The inlet side of the solenoid valve is exposed to normal transmission linepressure. The outlet side of the valve
leads to the valve body governor circuit.
The solenoid valve regulates line pressure to produce governor pressure.Theaveragecurrentsuppliedtothesole-
noid controls governor pressure. One amp current produces zero kPa/psi governor pressure. Zero amps sets the
maximum governor pressure.
The powertrain control module (PCM) turns on the trans control relay whichsupplies electrical power to the solenoid
valve. Operating voltage is 12 volts (DC). The PCM controls the ground sideof the solenoid using the governor
pressure solenoidcontrol circuit.
GOVERNOR PRESSURE SENSOR
The sensor output signal provides the necessary feedback to the PCM. This feedback is needed to adequately
control governor pressure.
GOVERNOR BODY AND TRANSFER PLATE
The transfer plate channels line pressure to the solenoid valve through the governor body. It also channels governor
pressure from the solenoid valve to the governor circuit. It is the solenoid valve that develops the necessary gov-
ernor pressure.
GOVERNOR PRESSURE CURVES
LOW TRANSMISSION FLUID TEMPERATURE
When the transmission fluid is cold the conventional governor can delay shifts, resulting in higher than normal shift
speeds and harsh shifts. The electronically controlled low temperature governor pressure curve is higher than nor-
mal to make the transmission shift at normal speeds and sooner. The PCM usesa temperature sensor in the trans-
mission oil sump to determine when low temperature governor pressure is needed.
NORMAL OPERATION
Normal operation is refined through the increased computing power of the PCM and through access to data on
engine operating conditions provided by the PCM that were not available with the previous stand-alone electronic
module. This facilitated the development of a load adaptive shift strategy - the ability to alter the shift schedule in
response to vehicle load condition. One manifestation of this capabilityis grade
huntingprevention - the ability of
the transmission logic to delay an upshift on a grade if the engine does not have sufficient power to maintain speed
in the higher gear. The 3-2 downshift and the potential for hunting betweengears occurs with a heavily loaded
vehicle or on steep grades. When hunting occurs, it is very objectionable because shifts are frequent and accom-
panied by large changes in noise and acceleration.
