As the speed of the turbine increases, th
e fluid spins faster and faster in the
direction of engine rotation. As a result, t he ability of the stator to redirect the
fluid flow is reduced. Under cruising conditions, the stator is eventually forced to
rotate on its one-way clutch in the dire ction of engine rotation. Under these
conditions, the torque converter begins to behave almost like a solid shaft, with
the torus and turbine speeds being almost equal.
PLANETARY GEARBOX
The ability of the torque converter to mult iply engine torque is limited. Also, the
unit tends to be more efficient when the turbine is rotating at relatively high
speeds. Therefore, a planetar y gearbox is used to carry the power output of the
turbine to the driveshaft.

Fig. 2: Planetary gears work in a sim ilar fashion to manual transmission gears,
but are composed of three parts
Planetary gears function very similarly to conventional transmission gears.
However, their construction is different in that three elements make up one gear
system, and, in that all three elements ar e different from one another. The three
elements are: an outer gear that is shaped like a hoop, with teeth cut into the
inner surface; a sun gear, mounted on a sha ft and located at the very center of

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 307
the outer gear; and a set of three planet gear
s, held by pins in a ring-like planet
carrier, meshing with both the sun gear and the outer gear. Either the outer gear
or the sun gear may be held stationary, providing more than one possible
torque multiplication factor for each se t of gears. Also, if all three gears are
forced to rotate at the same speed, the gearset forms, in effect, a solid shaft.

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.

EXTENSION HOUSING SEAL (IN VEHICLE)
REMOVAL & INSTALLATION
This seal controls transmission oil leakage around the driveshaft. Continued
failure of this seal usually indicates a worn output shaft bushing. If so, there will
be signs of the same wear on the driveshaft where it contacts the seal and
bushing. The seal is available and is fairly simple to install, with the proper tool.
1. Raise and safely support rear of t he vehicle to minimize transmission oil
loss when the driveshaft is removed.
2. Unbolt the driveshaft fr om the differential and center support bearing, if
equipped. Wrap tape around the bearing cu ps to keep them in place on
the universal joint and slide the sh aft out of the transmission.
3. Use a small pry tool to carefully pr y out the old seal. Be careful not to
insert the tool too far into the hous ing or the bushing will be damaged.
4. Use an oil seal installation tool to evenly drive the new seal into the
housing. Make sure the tool only cont acts the outer metal portion of the
seal.
5. Install the driveshaft. Torque the uni versal bearing cup retainer bolts to
15 ft. lbs. (20 Nm). Recheck fluid level.

DRIVELINE

DRIVESHAFT AND U-JOINTS
The U-joint is secured to the yoke in one of two ways. Dana and Cleveland
shafts use a conventional snapring to ho ld each bearing cup in the yoke. The
snapring fits into a groove located in eac h yoke end just on top of each bearing
cup. The Saginaw design shaft secures its U-joints in another way. Nylon
material is injected through a small hole in the yoke and flows along a circular
groove between the U-joint and the yoke , creating a synthetic snapring.
Disassembly of the Saginaw U-joint requi res the joint to be pressed from the
yoke. This results in damage to the be aring cups and destruction of the nylon
rings.
