Hello, a low pitch wine starts at around 30 km/h and is related to wheel speed. (rpms, clutch position, gear selection, steering or braking have no effect on the noise) It gets a little higher in pitch as speed increases and the loudness fluctuates a little. Not really loud though (ie. if the blower fan is on 3 it's heard to hear.) The noise seems to be coming from the the gearbox or under the front seats, but is hard to pinpoint. After about 15 minutes of driving, it improves by about 50% so that sometimes it's not there at all at any speed. Transmission functions well with all gears shifting smoothly.

I changed the transmission fluid which helped somewhat, but was disappointed to find some metal filings on the magnetic drain plug.

Is this transmission on it's way out?

Drive shaft need greasing? (I didn't see any grease nipples)

Other comments or suggestions?

Thanks.
