Maxima, Transmission Noise
Q: I have an Ď89 Nissan Maxima / SE with a 5 speed manual transmission
with 186,000 miles on it (it's been great). However, now while idling,
I'm getting a tapping noise, which sounds like itís coming from the bell
housing of the transmission. The noise is also present and louder when
starting off in first and second gear. Any ideas, suggestions? Mechanics
seem to think it a faulty bearing. Could it be the throw-out bearing??
throw-out bearing, when failing, usually is loudest when you step on the
clutch pedal. That is when the throw-out bearing is under the most load
The noise youíre describing, along with the shifting problems indicates
that there are internal transmission bearings that are failing. As a bearing
fails, small pieces of metal (bearing material) travel throughout the
rest of the transmission, causing and accelerating damage and wear to
other costly transmission components. Donít wait too long! Delaying the
needed repairs WILL drive the repair cost higher.
