20 min & some electrical tape to fix :-roll


Found the short. When my dog was a puppy - he chewed the shifter handle while I was out of the truck looking for a trailer. (I was proud of him for resisting the paper bag of french fries sitting on the dash....) - fast forward to a few years later, and the shift handle finally came apart at the seams. It worked, it's just ugly - but allowed enough movement to chaff the small wires inside the shift handle. A dab of liquid electrical tape on the wire itself, and about 3 ft of electrical tape wrapped around the handle have it working until a $65 replacement handle arrives in the mail.

Edit: This also fixed my unusual problems with throttle response under hard cornering and hard acceleration.

Super easy fix now that I know where to look.

If your dog didn't chew the handle like mine - open it up and check the wires in the column where you'll most likely find the short. If you get in a bind - you can just unplug the connector inside the column for the over-drive button, pop a new fuse in and drive the truck as long as you want... just without the convenience of the overdrive button.

Here is an excellent write up from Ken on another forum. This write up had me in and out with a completed repair in under 20 min.


F250 2WD Crew w/ ISSpro guages, 6637 intake, MBRP 4" exhaust, Riffraff High Pressure Crossover, Garrett Power Max BB turbo, Stage 2 Single Shot Injectors and DP tuner. Thanks to Clay at Riffraff. Update: 6.0 oil cooler, John Woods transmission, etc...

My 7.3 has no lights on when my peel goes dead and when it is working it seems like it didn't have the quick response it did before that problem started
