i get a wrench warning, all the gauges stop working except the Tachyometer, the car still drives, but feels like the wrong gear,

Hello, the wrench light can occur due to an electronic throttle body issue, or an automatic transmission issue. In this case, it sounds like the latter. Diagnostic testing is required to find out what is happening -- using a Ford compatible diagnostic tool -- like their IDS tool -- and checking actual transmission commands and operation, and also retrieving any diagnostic trouble codes the transmission failure may have set, which will give more clues as to where to look for the concern to start with.
