Transmission Clunk on Acceleration or Deceleration

Transmission Clunk on Acceleration or Deceleration

Diagnostic Aids
All manual transmissions 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 usually caused by wear between 2 components, or from improper assembly, which would also cause other symptoms.
