   You have to also consider the high mileage on the auto 
transmissions and the heavy loads they had been hauling with a big 
diesel engine behind them but still its a comparison that says the 
Dodge is stronger, the two problems that show up in the C-6 in the 
trucks are sun gear teeth chipping and planet bearing failure which 
may be worst in our application do to the higher rpm however in the 
case of 2.17 gearbox where the planet carrier is held still it would 
get better oiling than in the 2.85 units.
