Question: From no OBD codes to 12

After visiting a goat farm with my grandchildren, turned on ignition and got check engine light. Had to start in '1' to get car rolling. Never shifted out of 3rd for entire 80 mile trip home. Checked OBD codes and got: P1451, 1747,743,750,755,760,765,135,136,141,155,and 161.
Cleared codes and just idled car for a few seconds and got all codes except 136, 141 and 161.
Car has rebuilt trans 10K ago and passed emissions last month. Only thing I can think of is that I hit some bad pot holes just before goat farm. Car is VT 4.0L 245 CID FI GAS
N E. Thanks for your advice. Ralph

All those P07** codes are transmission related. I suspect it is either a wiring issue or a transmission failure. In any case, you will need a shop to look at it.

I have seen Fords set multiple codes like this because the 02 sensor shorted out (you do look like you have an 02 sensor or two code in that list) so you might look under the vehicle to see if the wiring has rubbed through somewhere or melted to the exhaust system.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
