bamlogisticsinc Posted 5 hours ago Share Posted 5 hours ago What causes it? Just something i noticed. 5 Speeds, 6 Speeds, 12 Speeds is what i noticed have that same sound, But the T2000 Series to NOT have that sound. The TRXL series seem to have a "gear whine" to them. Even the airshifted models have that same sound. There is also a noticeable loud fan sound kicking in at 4th gear. Anyone knows what causes it as opposed to the T2000 series? I would assume straight cut gears... Also, I would like to know if the Overdrive TRXL1070 has more of a "gear whine" than the TRXL107. Lookup "Appalacianrust" and his 1980 Mack R model hay hauler. That has the same noise im talking about. Heres an example, (by no means promoting his content, if thats against the rules, just a genuine question) Quote Link to comment https://www.bigmacktrucks.com/topic/76360-anyone-know-the-cause-of-the-trxl-series-to-have-gear-whine/ Share on other sites More sharing options...
