Transmission Clunk on Acceleration or Deceleration

Transmission Clunk on Acceleration or Deceleration

Diagnostic Aids

All manual transmissions and axles have gear play that might cause a clunk. If the transmission is suspected of causing the clunk, compare it with a similar vehicle. An internal clunk in the transmission is the natural response of the driveline to an impact, but may also be caused by improper assembly, which would also cause other symptoms.
