How is it possible for automatic transmission fluid to mix into the engines motor oil if not done intentionally 1995 Aerostar?
there is a vacum hose that attaches to the transmission. The vacum hose comes directly from engine vacum (as all vacum hoses are) If the valve on the transmission somehow gets old and simply breaks, then a small amount can be sucked up by engine vacum down the vacum hose and into engine compartment. I thought it virtually impossible until it happened to me.

What is wrong with a 1987 ford F150 if it starts to shift at a very high rpm?
I would start by looking for worn vacum line to modulator. Or the modulator could be bad. the modulator is located on the transmission which tells the transmission to shift when the vacum pulls a diaphragm inside the modulator a certain distance. some are adjustable with a flat blade screw i believe.
