Hello,
a few years ago I converted my 2005 V70R to single mass flwheel (http://kalmar-union.com/parts/volvo-transmission/) with standard clutch. No increased power.
That worked fine since 2013 with a steady gearbox rattle only when the oil is really hot. Only hearable outside. No rattle with cold oil.
But since a few weeks I hear massive louder gearbox rattle which has now some "irregular" metallic beats in between. Doesn't sound like a can of marbles anymore. More as if you throw some metal into a shredder.
When I depress the clutch pedal the noise completely disapprers. Formerly it also disappeared when the car was slowly rolling down the road (pedal depressed, gear engaged) but since a few weeks I also hear those irregular metallic beats during this condition.
The sound during acceleration when the oil is warm in the 1st-3rd gear is horrible. Sounds like if the gerabox will break into pieces within the next few meters.
I have uploaded a mp3 file I recorded yesterday after driving approx 150km (=almost 100mls): http://volvo-turbo.de/V70R/gearboxrattle.mp3
Engine idling. Sounds from gearbox are like an old diesel tractor.
Is that sound still coming from loose teeth (=not a "mechanical" sound) or do I have to expect an upcoming major gerabox damage?
Kind regards
Ingo
