Can anyone tell me at what RPM an 840 5 speed should upshift at wide open throttle?
The Tacho calibrations show broken orange warnings from 6000 to 6500 then its orange all the way suggesting redline, or what I believe to be the high end upshift. Mine changes at about 6600/6700 so I wonder if the trans computer has been modified. My dealer doesnt have a friggin clue but he did suggest that some 840s had a bad control map and that when dealers do a rebuild that they reprogram the TCU.
Any clues or stories of your own change points?
