I have a 1994 Ranger 2WD with a 4.0 liter engine, and an automatic transmission. Just recently one day it started shifting real late into 2nd gear, and the tranmission fluid level shows it to be way over full. Is this a governor issue? What is the cause of the transmission fluid level being way over full? Any ideas would be greatly appreciated. I know how to get the governor out, if it's in the extension housing on the transmission. When I get it out, what am I looking for? Should I just clean it and put it back together? Why does our local transmission shop say not to change the fluid on a transmission that hasn't had regular fluid changes. They say you will more then likely cause a problem if you do so.
