Wanna hear a true, sick story?? My cousin, one month ago, blew his tranmission on his 1ton Chevy '03 dually. Replaced with a big stout tranny, able to handle 900hp with a 150K warranty. Total cost: $6500.00. Got the truck back. Truck has 101,000miles on it. Within three days of having it back, he blew the Duramax motor. Oilpump went out, lost the bearings. Best cost at this point: $10,500.00, new short block and install. So basically, he's spent 17K in the last month on his truck w/ 101K miles on it.
