G56 Gear rollover facts:
When converting a G56 transmission over to a solid mass flywheel vs.
dual mass flywheel, gear rollover is inevitable. Gear rollover noise is
often heard when the vehicle is idling or under a load in low RPM
ranges (often referred to as sounding like marbles in the transmission).
This is completely normal.
Gear rollover noise is caused by reverse engine spike and can in
most cases be drastically reduced by simply changing the oil in the
transmission or reducing engine spike produced by inadequate engine
components (ex. misfiring injector, FCA problems, Electronic
programming). The oil recommended by the transmission manufacture
Mercedes-Benz is “Mobil Delvac Synthetic Transmission Fluid 50.” We at
Valair Inc. recommend draining completely and refilling with 7 quarts.
Only 6 quarts will fit when utilizing the fill hole, the final quart
will need to be filled through the shift tower.
On all dual and triple disc clutches, a noise will be
associated with the disengagement of the clutch. This is due to the
intermediate plate(s) floating freely in the lugs of the flywheel. This
is NOT a bad throw out bearing!!! The noise can possibly get more
noticeable during the break-in period of the clutch due to the
intermediate plate(s) seating in.
