It should provide some advanced warning of an impending failure, assuming the gears are shedding metal. =20 I believe it was Tom Parkes' turbo 20B w/Ross gearbox that he was running when his chip detector alerted him to metal chips in the gearbox oil, possibly averting an off-field landing, or worse. Is anyone else using a chip detector? Mark S. You have to also consider the high mileage on the auto=20 transmissions and the heavy loads they had been hauling with a big=20 diesel engine behind them but still its a comparison that says the=20 Dodge is stronger, the two problems that show up in the C-6 in the=20 trucks are sun gear teeth chipping and planet bearing failure which=20 may be worst in our application do to the higher rpm however in the=20 case of 2.17 gearbox where the planet carrier is held still it would=20 get better oiling than in the 2.85 units.
