hello I just replaced my battery in an 08 fusion now the wrench light is on and the owner manual says throttle/transmission problem? I have no throttle response. I am confused

 

Something you can try.
Remove the negative battery from the battery and connect it or hold it on the positive battery cable still on the battery for a few minutes. When done reconnect the negative cable to the battery and see what you get. This allows any glitches in the computer to drain down and is referred to as a forced/soft reset. Many times it will allow a fresh start for all/most systems.

 

Did that. I have never seen so much trouble out of just replacing a battery omg.
