|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.

These clutches utilize ceramic buttons on both sides of the clutch disc and are aimed at the performance trucks. Driving manners are very performance oriented with no clutch slip, basically the clutch is in, or it is out. Great holding capacity for modified trucks, the only way you will get more holding power is to go to a Dual Disc Clutch setup. Ceramic is a very hard material so typically flywheel wear is more noticeable using a ceramic
clutch than with other materials. This clutch has a small window of usage, ideally suited to trucks with performance power modifications that do not intend to tow with there truck. (Not recommended for towing) If you plan on drag racing/ sled pulling or doing boosted launches you will need a Dual Disc Clutch.
