hi Scotty I love your video's been watching for long time and I'm having a problem with my car but I've never heard before 2003 Mercury Grand Marquis GS transmission works then stops then we'll re-engage shifting gears I've never heard of that before it's easier transmission goes or at works I've never had it on and off on and off whether it's cold or hot and I was just wondering if maybe you have heard through your many years of what it might be it is full of fluid it has 170,000 miles and it's automatic
what it might be
It might be the transmission is wearing out after 2 decades and 170K miles. When is the last time it was serviced? Fluid look OK (not gritty or burnt)?
Or it might just be a problem with shift solenoids. You need a transmission expert with a fancy scan tool to determine that.
