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.
Ceramic/Kevlar 500HP & 1000 Ft-lbs.
Utilizing two different buttons on the clutch disc these clutches are aimed at the moderate performance trucks. Driving manners are very good for everyday driving and towing. Take-off is relatively smooth and offer more slip and forgiveness than the ceramic/ceramic clutches. While the holding power for the Kevlar faced clutch is higher than the organic/organic faced clutches, the main advantage is less wear on the flywheel and longer life. Ideally suited to trucks with moderate performance power modifications. If towing more than the occasional 7,500-10,000lbs the Organic Dual Disc will be a better option.
