Buzzing From the Engine or Transmission While Decelerating

(Supersedes 00-054, dated March 20, 2001)

SYMPTOM

While decelerating in 3rd or 2nd gear, a buzzing or

rattling comes from the engine or transmission

between 4,000 and 3,000 rpm. This noise sounds

similar to a heat shield rattle, and it goes away if you

press lightly on the accelerator pedal or disengage the

clutch.

PROBABLE CAUSE

Gear backlash in the transmission.

BACKGROUND

Clearance between transmission gears (backlash) is

normal and sometimes audible. In an S2000, this noise

is more noticeable since the transmission is between

the seats instead of up front in the engine

compartment. When the vehicle decelerates, its

weight, together with the pulses from the engine,

excites the transmission gears, causing them to buzz

or rattle.

The four springs in the clutch disc hub act as a damper.

The clutch disc listed in this service bulletin is an

improved version of the countermeasured disc

released a year ago. Extensive testing has shown it to

be quieter than any previous S2000 clutch discs.

If your customer had the previous clutch disc installed

but still complains of deceleration noise, install the

clutch disc listed in this service bulletin.

CORRECTIVE ACTION

Replace the clutch disc with the improved clutch disc.
