Has anyone heard of a tbc fault flashing and affecting back up? I started truck and put it in reverse it acted like I had parking brake on. I checked fuse#12 it was ok..disconnected both batteries to attempt a reset. Still no good. Truck will drive forward but will not reverse. Oh and have no trailer hooked up and live in Las Vegas with absolutely no rain when this happened. Now..brakes had started to grind a bit and was about to take it to shop..then this tbc issue with no reverse happened. Help!!

 

Now I'm getting it!<br/>No trailer attached.<br/>Happens anytime & random.<br/>2006 F250SD 5.4L auto 4x4 <br/>

 

For what it's worth...

I have a 2005 XLT and 2006 King Ranch both with the integrated brake control and while I have had plenty of corrosion issues with the plug/harness and 7-way receptacle on the trucks over the years, I have only ever seen the TBC fault and beep show up on my dash cluster when the actual TBC was bad. Having 2 trucks is great for troubleshooting and when my '05 showed the TBC fault I pulled the TBC out of the '06, installed it in the '05 and never had the error code again.

I have since had corrosion issues with the factory 7-pin and such requiring replacement 7-pin receptacle and some wire repairs to the harnesses at the rear of the truck but never once has the TBC fault showed up again.
