BODY-VALVE
DESCRIPTION
The valve body consists of a cast aluminum valve body, a separator plate, and transfer plate. The valve body con-
tains valves and check balls that control fluid delivery to the torque converter clutch, bands, and frictional clutches.
The valve body contains the following components.
By adjusting the spring pressure acting on the regulator valve, transmission line pressure can be adjusted.
Regulator valve (2)
Switch valve (3)
Regulator valve spring (4)
Kickdown valve (5)
Kickdown detent (6)
Throttle valve and spring (7)
Manual valve (8)
1-2 Governor plug (9)

2-3 Governor plug (12)

1-2 SHIFT CONTROL VALVE
It contains a valve with four lands and a spring. It is used as both a “relay” and “balanced” valve.
The valve has two specific operations :
Aid in quality of the 1-2 upshift.
Aid in the quality and timing of the 3-2 kickdown ranges.
When the manual valve is set to the DRIVE position and the transmission is inthe first or second gear range, 1-2
shift control or “modulated throttle pressure” is supplied to the middle of the accumulator piston by the 1-2 shift
control valve. During the 1-2 upshift, this pressure is used to control thekickdown servo apply pressure that is
needed to apply the kickdown and accumulator pistons. Thus, the 1-2 shift point is “cushioned” and the quality is
improved. During a WOT kickdown, kickdown pressure is applied between thekickdown valve and the 1-2 shift
control valve. This additional pressure is directed to the 1-2 shift control’s spring cavity, adding to the spring load on
the valve. The result of this increased “modulated” throttle pressure is afirmer WOT upshift.
1-2 Shift Control Valve

Once the TCC control valve has moved to the right, line pressure is directedto the tip of the switch valve, forcing
the valve to the right. The switch valve now vents oil from the front of the piston in the torque converter, and sup-
plies line pressure to the (rear) apply side of the torque converter piston. This pressure differential causes the piston
to apply against the friction material, cutting off any further flow of line pressure oil. After the switch valve is shuttled
right allowing line pressure to engage the TCC, torque converter pressureis directed past the switch valve into the
transmission cooler and lubrication circuits.
CONVERTER CLUTCH LOCK-UP VALVE
The torque converter clutch (TCC) lock-up valve controls the back (ON) side of the torque converter clutch. When
the PCM energizes the TCC solenoid to engage the converter clutch piston, pressure is applied to the TCC lock-up
valve which moves to the right and applies pressure to the torque converterclutch.
CONVERTER CLUTCH LOCK-UP TIMING VALVE
The torque converter clutch (TCC) lock-up timing valve is there to block any 4-3 downshift until the TCC is com-
pletely unlocked and the clutch is disengaged.
SHUTTLE VALVE
The assembly is contained in a bore in the valve body above the shift valves.When the manual valve is positioned
in the Drive range, throttle pressure acts on the throttle plug of the shuttle valve to move it against a spring, increas-
ing the spring force on the shuttle valve. During a part or full throttle 1-2upshift, the throttle plug is bottomed by
throttle pressure, holding the shuttle valve to the right against governor pressure, and opening a by–pass circuit.
The shuttle valve controls the quality of the kickdown shift by restricting the rate of fluid discharge from the front
clutch and servo release circuits. During a 3-2 kickdown, fluid discharges through the shuttle by-pass circuit. When
the shuttle valve closes the by-pass circuit, fluid discharge is restricted and controlled for the application of the front
band. During a 2-3 “lift foot” upshift, the shuttle valve by-passes the restriction to allow full fluid flow through the
by-pass groove for a faster release of the band.
Manual Valve

BOOST VALVE
The boost valve provides increased fluid apply pres-
sure to the overdrive clutch during 3-4 upshifts, and
when accelerating in fourth gear.

The valve body can be removed for service without having to remove the transmission assembly.
The valve body can be disassembled for cleaning and inspection of the individual components.

DISASSEMBLY
CAUTION: Do not clamp any valve body component in a vise. This practice can damage the component
resulting in unsatisfactory operation after assembly and installation.Do not use pliers to remove any of the
valves, plugs or springs and do not force any of the components out or into place. The valves and valve
body housings will be damaged if force is used. Tag or mark the valve body springs for reference as they
are removed. Do not allow them to become intermixed.

7. Lubricate solenoid case connector (1) O-rings and
shaft of manual lever with light coat of petroleum
jelly.

locating tang that fits indimple at top of accumula-
tor housing (2). Seat tang in dimple before tighten-
ing connector screw.
9. Install solenoid assembly and gasket. Tighten sole-
noid attaching screws to 8 Nꞏm (72 in. lbs.) torque.
10. Verify that solenoid wire harness is properly
routed. Solenoid harness must be clear of manual
lever and park rod and not be pinched between
accumulator housing and cover.

adjusting screw bracket.
13. Position adjusting screw bracket on valve body.

Install short, upper bracket screws first and long
bottom screw last. Verify that valve springs and
bracket are properly aligned. Then tighten all
three bracket screws to 4 Nꞏm (35 in. lbs.) torque.

TRANSAXLE/AUTOMATIC/VALVE BODY - ADJUSTMENTS)
GOVERNOR BODY, SENSOR AND SOLENOID
1. Turn valve body assembly over so accumulator side of transfer plate is facing down.

5. Install governor pressure solenoid in governor body. Push solenoid in until it snaps into place in body.
6. Position governor body gasket on transfer plate.
7. Install retainer plate on governor body and around solenoid. Be sure solenoid connector is positioned in retainer
