Torque Converter: All Technical Service Bulletins
Engine - Knocking Noise From Engine Compartment

Model Year 1983

Bulletin No. 83-134

File In Group 60

Number

35

Date

June '83

SUBJECT:

KNOCKING NOISE FROM ENGINE COMPARTMENT

MODELS AFFECTED: ALL ENGINES

Loose torque converter bolts sound much like a bearing knock and will give several raps on a quick acceleration (engine running free). With the
transmission in gear, the noise may or may not appear at idle depending on the idle smoothness.

Check torque converter to flywheel mounting bolts before attempting to repair any engine for bearing-type knock.
