Troubleshooting: Trouble
Shifting Gears
|
|
|
|
Your vehicle may have a
transmission problem if: |
 |
Your transmission is not
going into, or staying in gear |
|
|
Shifting is harsh or
delayed |
|
|
|
This is a relatively
common problem, and it could be caused by any of
a number of possibilities: |
|
|
An internal transmission
repair may be necessary if parts within the
transmission |
| |
are worn or
damaged |
|
|
External controls for the
transmission may simply need adjustment |
|
|
External controls may need
replacement |
|
|
Electrical components may
need adjustment or replacement |
|
|
|
|
Because today’s cars, trucks and SUVs are
controlled by computers, it takes a real transmission expert
to properly diagnose your problem. These problems should not
be ignored—the longer they continue, the more damage may be
caused. Before your vehicle becomes inoperative, take your
car to the experts at AAMCO for an External Diagnostic
Service. Our comprehensive process begins with a series of
tests to narrow down exactly what your problem might be.
This examination will help determine if you just have an
external problem or if you possibly have another type of
malfunction or internal transmission problem. The Free
External Diagnostic Service
includes putting your car on a lift, examining the external
controls and fluids, and road testing your vehicle. If you
only have an external problem the specialists at AAMCO
centers can take care of the problem before it develops into
something bigger. If the certified technician uncovers a
more serious malfunction, then we will discuss with you the
other services that may be necessary to get your vehicle
back on the road as soon as possible. With that kind of
care, you won’t want to take your vehicle anywhere else. |

Troubleshooting:
Transmission
Seems To Be Slipping |
|
|
|
If the transmission slips between gear
changes, this is likely a transmission problem—a
transmission is designed to hold effortlessly in each gear
at predetermined speeds. If you move the selector for your
automatic transmission to “Drive” and the engine seems to be
racing ahead faster than the transmission, that is another
common symptom of a transmission problem. Trained
transmission technicians at AAMCO centers can help determine
which of the following possibilities could be causing the
problem: |
|
|
An internal transmission
repair may be necessary if parts within the
transmission |
| |
are worn or damaged |
|
|
External controls for the
transmission may simply need replacement or
adjustment |
|
|
Electrical controls or
components may need adjustment or replacement |
|
|
The transmission fluid
level may be low, or there is insufficient fluid
pressure |
|
 |
|
| Because today’s
cars, trucks and SUVs are controlled by computers,
it takes a real transmission expert to properly
diagnose this problem. The right diagnosis can save
you time and potentially a substantial amount of
money. These problems require immediate
attention—the longer they continue, the more damage
may be caused. Take your car, truck or SUV to the
experts at AAMCO for an External Diagnostic Service.
Our certified technicians will help get your vehicle
back on the road as soon as possible. |

Troubleshooting: Noise
In The Transmission |
|
|
|
If you hear noise coming from your vehicle’s
transmission, it may indicate that transmission parts are
hitting together abnormally. Normally-functioning
transmissions are virtually free of noise, when clean
transmission fluid is lubricating the moving parts. |
|
|
|
Tracking down the source of the noise can be
complicated. Unlike many other repair facilities, AAMCO
Center technicians are experts in all systems in your car,
truck, and SUV and perform both external transmission
diagnostics and a complete car check. So they know the
difference between a simple exhaust problem causing
noises—and a potentially significant transmission problem. |
|
|
|
Your vehicle may very
likely have a transmission problem if: |
|
|
There is buzzing or any
other noise from the transmission |
|
|
If your vehicle is a
four-wheel drive, there is a clicking noise in the
transmission while it is in |
| |
4-wheel drive mode |
|
|
There is a clunking from
under the vehicle when you change gears |
|
|
|
|
Trained transmission
technicians at AAMCO Centers can help determine if it even
is a transmission problem, and which of the following
possibilities could be causing the problem: |
|
|
|
|
|
Take your car, truck or SUV to the experts at
AAMCO for an External Diagnostic Service. Our certified
technicians will help get to the bottom of your problems and
get your vehicle back on the road as soon as possible. |

Troubleshooting:
Transmission Fluid Leaking |
|
|
|
A transmission fluid leak
is not something to ignore. The transmission fluid serves
several purposes of critical importance to the life of your
transmission: |
|
|
The fluid transfers power
from the engine to the transmission, and provides
|
|
|
the necessary pressure to
operate the transmission. |
|
|
Transmission fluid also cools and
lubricates the transmission. |
|
|
|
|
As the amount of transmission fluid goes
down, the ability to operate and keep the transmission cool
is reduced. Overheating quickly causes damage to a
transmission that may ultimately result in the need for a
costly repair. |
|
|
| Leaks can occur from several
different areas external to the transmission, or
they may be internal to the transmission. The
repairs required could be relatively minor, or the
signs could point to a major problem. It takes an
expert to tell. |
 |
| |
| Regardless of what the source of
the leak is, it requires immediate attention. The
longer the leaks continue, the more damage that may
result. Trust the expert transmission technicians at
AAMCO to get you and your vehicle back on the road
as soon as possible. |

Troubleshooting: Vehicle Is
Not Moving |
|
|
|
 |
If your vehicle will not move, or
you are concerned about driving it any further, call
your nearest AAMCO Center. If your vehicle needs to
be towed, your AAMCO center can make the
arrangements. |
| |
| Once your vehicle is towed to the
nearest AAMCO Center, our expert technicians will do
a thorough check of the external controls/components
to determine why the vehicle is not moving. Our
technicians check the transmission fluid level and
condition. We’ll check the level and condition of
your transfer case and differential fluid (where
applicable). We’ll check under the hood and under
the car to get up close to all of the possible
causes external to the transmission of the vehicle’s
problem. AAMCO’s External Diagnostic Service is the
gold standard in the transmission business. |
| |
| Our technicians are experts in
transmissions and complete car care, so we’ll put
your car through AAMCO’s comprehensive 36-point
ProtectCheck. No matter what your car, truck or
SUV’s problem, the experts at AAMCO will get to the
bottom of it. And get you and your vehicle back on
the road as soon as possible. |

Troubleshooting: Check Engine
Light |
|
|
|
The CHECK ENGINE LIGHT on your instrument
panel can light up for a wide variety of reasons, often
related to emissions, the engine, or the transmission. We
urge you not to ignore the CHECK ENGINE LIGHT when it
illuminates, but to have your vehicle checked out. According
to a national survey, more than one in ten drivers admit
they drive with the CHECK ENGINE LIGHT on—approximately 20
million vehicles per week. |
 |
|
| There could be a simple solution,
or it could be a warning sign of a much more severe
condition. AAMCO Centers can diagnose whatever the
problem may be. |
