Buying New Tires
GM has developed and matched specific tires for your
vehicle. If you need replacement tires, GM strongly
recommends that you get tires that are the same size,
brand, load range, speed rating, and construction
type (radial and bias-belted tires) as your vehicle’s
original tires. This way, your vehicle will continue to have
tires that are designed to give the same performance
and vehicle safety, during normal use, as the original
tires. SeeTire Sidewall Labeling on page 5-46for
additional information.
{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes,
brands, or types (radial and bias-belted tires),
the vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes, brands, or types may also cause
damage to your vehicle. Be sure to use the
correct size, brand, and type of tires on all
wheels. It is all right to drive with your
compact spare temporarily, as it was
developed for use on your vehicle. See
Compact Spare Tire on page 5-66.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.
Your vehicle’s original equipment tires are listed on the
Tire and Loading Information Label. This label is
attached to the vehicle’s center pillar (B-pillar). See
Loading Your Vehicle on page 4-27, for more information
about the Tire and Loading Information Label.
Different Size Tires and Wheels
If you add wheels or tires that are a different size than
your original equipment wheels and tires, this may
affect the way your vehicle performs, including its
braking, ride and handling characteristics, stability, and
resistance to rollover. Additionally, if your vehicle
has electronic systems such as, anti-lock brakes,
traction control, and electronic stability control, the
performance of these systems can be affected.

Engine Cooling System Inspection
Inspect the hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment. You may need to have
your brakes inspected more often if your driving
habits or conditions result in frequent braking.

A. Front Planetary Gear
B. Rear Planetary Gear
Reverse Gear
1. The input shaft rotates clockwise.
The reverse clutch (C3) operates. Connect the input shaft to the rear planetary sun gear.
2. The planetary long pinion rotates itself counterclockwise.
3. The 1st and reverse brake (3) operates. Lock rotates the planetary carrier.
4. The ring gear rotates counterclockwise.
5. The counter drive gear rotates counterclockwise for the ring gear and one.
6. The counter driven gear rotates clockwise.
7. The differential gear drive pinion rotates clockwise for the counter driven gear and one.
8. The differential gear rotates counterclockwise.
Engine Brake
The driving force is connected to the input shaft directory without the 1-way clutch. Therefore the engine brake
operates.
TRANSMISSION GENERAL DESCRIPTION
The new automatic transmission AISIN (81-40LE) is an electronically controlled 4-speed automatic
transmission with lock-up mechanism.
The transmission is mainly composed of the torque converter with lock up clutch, newly developed 4-speed
planetary gear unit, the hydraulic control system and the electric control system.
Hydraulic Control System
Based on the hydraulic pressure created by the oil pump, the TCM sends signals to the solenoid and the
hydraulic control system governs the hydraulic pressure acting on the torque converter, planetary gear, clutches,
and brakes in accordance with the vehicle driving conditions.
Function of Components
NOTE: Lack of basic knowledge of this powertrain when performing diagnostic
procedures could result in incorrect diagnostic performance or damage to
powertrain components. Do not attempt to diagnose a powertrain problem
without this basic knowledge.

counterclockwise.
21st and Reverse BrakePrevents the planetary carrier from turning
either clockwise or counterclockwise.
8No. 1 One-Way ClutchWhen 4 is operating, this clutch prevents rear
sun gear from turning counterclockwise.
1No. 2 One-Way ClutchPrevents the planetary carrier from turning
counterclockwise.
Planetary Gear
These gears change the route through which
driving force is transmitted, in accordance
with the operation of each clutch and brake, in
order to increase or reduce the input and
output speed.
