TRANSMISSION DIAGNOSTIC

The right diagnosis is everything and we treat it like a science. Our technicians are skilled specialists who use their expertise and top-notch diagnostic equipment to troubleshoot, so that you save time and money.
With hundreds of AAMCO Centers across North America, AAMCO centers service more transmissions in a day than most dealers do in a year and we've been satisfying customers for more than 50 years.

Regardless of the cause, transmission problems require immediate attention. The longer they are allowed to continue, the more damage they may cause. Before your vehicle becomes inoperative, take your car to the experts at AAMCO for an External Diagnostic Service. Our certified transmission technicians will help get your vehicle back on the road as soon as possible.

TROUBLE SHIFTING GEARS

Your vehicle likely has a transmission (or clutch) problem if:

• Your transmission is not going into, or staying in gear
• Shifting is difficult or delayed
• Your gears are grinding
• The clutch pedal on your manual transmission is not working properly

The problem may be one of several possibilities:

• External controls need adjustment
• External controls need replacement
• Electrical components need adjustment or replacement
• In an automatic transmission, the transmission computer may need replacement
• An internal, or major repair, may be necessary (if parts within the transmission have been damaged)

TRANSMISSION SEEMS TO BE SLIPPING

If your transmission is slipping between gear changes, or if your clutch seems to be slipping, you might have a transmission problem. A transmission is designed to hold effortlessly in each gear at predetermined speeds.

If it does not, the problem may be one of several possibilities:

• External controls need adjustment
• External controls need replacement
• Electrical components need adjustment or replacement
• In an automatic transmission, the transmission computer may need replacement
• Low fluid level or insufficient fluid pressure
• The clutch needs adjustment or replacement
• Internal parts may be worn or damaged which may require a major repair

TRANSMISSION FLUID LEAKING

The transmission fluid serves to cool and lubricate.
A transmission leak, as with any transmission problem, is not something to ignore.

Bring your vehicle in if:

• There is a clicking noise in transmission while in 4-wheel drive
• There is a clunking from under the vehicle when you change gears

With an automatic transmission, the fluid also transfers power, and provides the necessary pressure to operate the transmission. As the amount of transmission fluid goes down, the ability to operate and keep the transmission cool is reduced.

• Overheating causes damage to a transmission that could ultimately cause a major repair

VEHICLE IS INOPERATIVE

Regardless of the cause, if your vehicle is inoperative, and you think it might have a transmission problem, call your nearest AAMCO center. If your vehicle needs to be towed, your AAMCO center can make the arrangements.

• Transmission problems require immediate attention.
• The longer they are allowed to continue, the more damage they may cause.

Take your car to the experts at AAMCO for an External Diagnostic Service. Our certified transmission technicians will help get your vehicle back on the road as soon as possible.

NOISE IN THE TRANSMISSION

Noise can indicate that transmission parts are hitting together abnormally, which should not happen in a normally-functioning transmission, and when clean transmission fluid is lubricating the moving parts. A transmission should make little noise when operating properly.

Your vehicle likely has a transmission (or clutch) problem if:

• There is buzzing or any other noise from the transmission.
• There is a clicking noise in transmission while in 4-wheel drive.
• There is a clunking from under the vehicle when you change gears.

The problem may be one of several possibilities:

• The transmission fluid is low, dirty, or incorrect.
• There is an internal problem in the transmission or transfer case.
• There are external controls or parts that need adjustment or replacement.
• Electrical components need adjustment or replacement.
• In an automatic transmission, the transmission computer may need replacement.
• Internal parts may be worn or damaged which may require a major repair.
