Trouble Shifting Gears
Any of the following are common symptoms of a manual transmission or clutch problem:
  • The clutch pedal will not move down.
  • The clutch pedal drops to the floor when you push on it. Even when the pedal is depressed, the gears cannot be changed. This problem can occur suddenly, or changing gears can become more difficult each time you shift.
  • The gear shift suddenly will not move, or it resists, as you push in the clutch pedal.
In any of these situations, do not attempt to shift gears or force the clutch pedal down. This vehicle should be towed to your local AAMCO center for the AAMCO External Diagnostic Service for manual transmission vehicles.

The problem could be caused by any of a number of possibilities, including:
  • There is an internal problem in the transmission if parts within the transmission are worn or damaged
  • The clutch linkage is binding
  • The clutch cable is broken or disconnected
  • There is no fluid or there is a leak in the hydraulic clutch circuit
  • The clutch may not be disengaging
It takes an expert to tell. AAMCO Center technicians are the experts in all types of transmissions, manual or automatic.


Pops Out Of Gear
When you press on, or let off the gas pedal, the gearshift jumps into the neutral position, leaving the transmission out of gear. This problem becomes more frequent over time.

This may mean that the shift linkage needs to be adjusted, or that there is an internal problem in the transmission. It takes an expert to tell. AAMCO center technicians are the experts in all types of transmissions, manual or automatic. Take your car, truck or SUV to your local AAMCO center for the AAMCO External Diagnostic Service for manual transmission vehicles. We'll get to the bottom of the problem and get you and your vehicle back on the road as quickly as possible.



Grinding
In this situation, the clutch pedal and gearshift work normally. But when you move the gear shift into gear and release the clutch, a grinding noise is heard and a vibration can be felt through the gearshift.

This symptom typically means one of the following:
  • There is an internal problem in the transmission if parts within the transmission are worn or damaged
  • The clutch is worn or needs adjustment
  • The shift linkage needs to be adjusted
Because the problem generally gets worse over time and can cause severe damage to your transmission, we urge you to take your car, truck or SUV to your local AAMCO Center for the AAMCO External Diagnostic Service for manual transmission vehicles as soon as possible. AAMCO Center technicians are the experts in all types of transmissions, manual or automatic.



Clutch Slipping
As you shift into gear and engage the clutch, the engine speeds up, but the car does not. The clutch seems to be slipping.

Generally this means the clutch is worn or needs adjustment, but there is the potential of internal transmission damage. It takes an expert to tell. AAMCO Center technicians are the experts in all types of transmissions, manual or automatic. This problem may worsen with time, making your vehicle unsafe to drive and should be taken care of immediately to prevent additional damage to the clutch assembly.

Take your car, truck or SUV to your local AAMCO Center for the AAMCO External Diagnostic Service for manual transmission vehicles. We’ll get to the bottom of the problem and get you and your vehicle back on the road as quickly as possible.


Noise When Shifting Gears
When you shift gears you feel a slight pause, then hear a clunk. It may sound like it is coming from the front or rear of the car. This problem will likely gradually get worse.

Typical causes of this problem include:
  • There are worn constant velocity joints(CV joints) or Universal joints (U-joints)
  • The differential unit may be worn and may have too much backlash
AAMCO Center technicians are the experts in all components of the drive train: CV joints, U-joints, differentials, and axles. Take your car, truck or SUV to your local AAMCO Center for the AAMCO External Diagnostic Service for manual transmission vehicles. We’ll get to the bottom of the problem and get you and your vehicle back on the road as quickly as possible.
