- 6.7 Turbo Cummins
My 2012 2500 HD 4x4 with 6.7 cummins seems to have entered into SafeMode. The transmission starts a full slippage in fourth gear, then continues slippage in all lower gears until the truck slows enough to manually shift into first or second gear. Drove the truck home in third gear, 8 miles. The motor and transmission temps were all in the normal range, engine 197, tranny 152. The truck has had all deletes done for over 8 years and no problems. This has occurred totally without warning, no drops in performance or any other signs. I use the truck primarily as a weekend/recreational vehicle, trips to the lumber yard and towing a Toy Hauler to motorcycle rallies. Total millage is just over 90,000 miles. The only issue ever with the truck was worn front spindle bearings, replaced the entire spindle assembly on both sides. Some that i have visited with feel the problem is with the valve body in the transmission and recommend a complete service and maybe the valve assembly upgrade. Bike rally season has started and I really need this fixed.
Anyone experience the same?
Remedies?
I limped home and did the three click ignition trick to see all my error coded vie the trip "b" odometer. It shot me 21 different codes. Many were from all the deletes i have, but the others really dont make sense. They range from low voltage, high readings on some circuits, to the dreaded 0606 Internal Control Processor. All the crazy codes tend me to think maybe a bad wire, draining voltage from the processor, low voltage just makes technology do sketchy stuff. Don't want to take it to a dealer, because all they see is $$$$.
Has anyone out there ever encountered the Safe Mode aka long drive home mode? Were you able to remedy or go straight to the dealer?
