Okay guys I know I seem different sites with multiple problems similar to mine but here we go I need your guys's help I have a big family in a tight budget. So while driving down the highway about a month ago my overdrive light started flashing on my 2000 Ford Excursion with the 6.8 liter V10 after I Coast it to the side of the highway of course my motor went into limp mode I told it the 280 miles from where I was at to a transmission shop in the town I live they inform me that my transmission fluid look great they could not identify any slippage so they thought it was a short after having it for 3 weeks they informed me that they look through the steering column keeping in mind I'm going by what the transmission shop told me. They looked through the steering column at the wiring they look at wiring underneath my hood and I believe at the transmission after 3 weeks of trying to diagnose the short and repeated repeatedly replacing number 19 fuse the PCM started communicating with the engine and the transmission again and the fuse quit blowing as of Mother's Day my grandmother passed away they had driven my Excursion for 3 days as a shop truck trying to get the situation to duplicate again they called me informed me that he had taken it down rough gravel roads drove it around in his field toad different shop vehicles around on the trailer with my Excursion and could not get anything to happen I drove 120 miles to my grandmother's funeral yesterday I got within 2 miles of the funeral and it popped the number 19 PCM fuse again and left me and my family of 7 stranded on the side of the road. This is mine and my kids only transportation to and from work the doctor and everything else and I hate to have it setting in another transmission shop for another month while somebody's trying to diagnose this problem. Any help would be greatly appreciated I have heard rumors from multiple parties that it could be the overdrive button it could be a wire on the steering column which the shopping for me they had already checked I heard it could be a sensor underneath the transmission pan Which sensor I'm not sure also heard it could be the speed sensor on the front of the transmission on the back of the transmission and on my rear axle I was also informed it could be a blown mass air flow air intake temperature switch in my breather box I was also informed it could be one of the three O2 sensors now on inspection waiting to get a ride to my grandmother's funeral I crawled underneath my extremely lifted Excursion and could not see any bare wires on the 3 O2 sensors so if anybody has any ideas please let me know as stated above I am on a budget and really cannot afford to miss three weeks worth of work while my vehicle sets in the shop. As soon as I can get my friend to get here with a tow truck and a trailer I will get this back to my garage and run and post any codes that are shown the last codes I recorded were the torque converter clutch shift solenoids A&B and then of course my Purge and Evac sensors for being in limp mode and I cannot remember the valve body code that it through but until I can rerun codes and post them for you guys I would appreciate any ideas

 

Do not cross-post (creating multiple posts in multiple sections). it only gums things up.

 

Yep and adding paragraphs now and again helps tremendously too----these walls of text make for difficult reading.
