Torqshift trans inE450 super duty
In tow mode it now doesn't shift into 4th gear until 4300RPM and 54MPH. It didn't due this until recently.Before it shifted at lower RPM and MPH. The Ford dealer says that this is a normal shift point,but I disagree as it didn't due this before. Any help as how to fix this problem or what are the correct shift points would be helpful.
