Can you disable overdrive on a 1994 Ford Thunderbird LX?

How do you get to the bolts around the bell housing for removal of the oil pan on a 1994 m50 engine?
What is wrong with a car when the 'Overdrive Off' light continues to blink and you can't turn it off?
I have a 1994 Ford Taurus SHO and ever couple of weeks this OVERDRIVE OFF lite flashes for a couple of days then goes off. I suspect it has something to do with the transmission and its electronic sensors. Take your car to a transmission shop and hook up an analyzer to the ECM for the transmission. It also can be related to the Vehicle Speed Sensor. This sensor feeds to the ECM and if…
