ADJUSTMENTS
Do not stretch cables or chains to make pins fit or holes align. This will prevent
the engine from returning to idle.
CABLE TYPE 1. Check that the cable is properly installed and that the throttle is closed to
the idle position.
2. Pull the servo end of the cable towa rd the linkage bracket of the servo.
Place the servo connector in one of the 6 holes in the bracket which
allows the least amount of slack and does not move the throttle linkage.
3. Install the retainer clip. Check that the throttle linkage is still in the idle
position.
ROD WITH SCREW ADJUSTER 1. Inspect the rod assembly for proper attachment to the servo and throttle\
stud. Make certain the throttle is at idle.
2. Adjust the slotted bra cket or the rod to obtain a clearance of 0.02-0.04 in.
(0.5-1.0mm) between the throttle stud and the end of the bracket slot.
3. Install the retainer clip; make certain the throttle is still at idle.
ROD WITH ADJUSTMENT HOLES 1. Inspect the rod to be sure it is securely connected to the servo and
throttle linkage; make certain the throttle is at idle.
2. Install the retainer pin in the hole which provides the least slack between
the servo bracket and the retainer.
3. Check the throttle; it must still be in the idle position.

modulator pressure rises as the thro
ttle is opened wider. By responding to these
two pressures, the shift valves caus e the upshift points to be delayed with
increased throttle opening to make the bes t use of the engine's power output.
Most transmissions also make use of an auxiliary circuit for downshifting. This
circuit may be actuated by the throttle linkage the vacuum line which actuates
the modulator, by a cable or by a solenoid. It applies pressure to a special
downshift surface on the shift valve or valves.
The transmission modulator also governs the line pressure, used to actuate the
servos. In this way, the clutches and bands will be actuated with a force
matching the torque output of the engine.
IDENTIFICATION

Two types of transmissions are used on th e vehicles; Turbo Hydra-Matic 200C
3-speed and Turbo Hydra-Matic 700-R4 4-speed. Beginning in 1991, the 700-
R4 was redesignated the 4L60.

e to the park detent and then back to
neutral.
5. Tighten cable attachment to 11 ft. lbs. (15 Nm).
The lever must be held out of P when tightening the nut.
SHIFT LINKAGE 1. Place the manual shaft of the transmission in N. Place the console shift
lever in N.
2. Install the cable in the slot of the shift lever. Adjust the cable so that the
pin has free movement.
3. Install and tighten t he nut to the pin.
THROTTLE VALVE CABLE 1. After installation of the cable to the transmission, engine bracket, and the
cable actuating lever, check to assure that the cable slider is in the zero
or fully re-adjusted position.
2. If cable slider is not in zero or fully re-adjusted, depress and hold the
metal re-adjust tab. Move the sli der back through the fitting in the
direction away from the cable actuat ing lever until the slider stops against
the fitting. Release the metal re-adjust tab.

INTAKE MANIFOLD
REMOVAL & INSTALLATION
When servicing all vehicles, be absolutel y sure to mark vacuum hoses and
wiring so that these items may be properly reconnected during installation. Also,
when disconnecting fitting lines (fuel lines, power brake vacuum lines,
transmission and engine cooler lines, etc.), always use two flare nut (or line)
wrenches. Hold the wrench on the large fitti ng with pressure on the wrench as if
you were tightening the fitting (clockw ise), THEN loosen and disconnect the
smaller fitting from the larger fitting. If this is not done, damage to the line will
result. Always relieve fuel system pressure before disconnecting lines.
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is contaminated or several years old.
