WHERE IS THE OVERDRIVE WIRE ON A 1993 OLDSMOMILE CUTLASSS CIERA

Get them on the phone first & go from there

with that milage go with the rebuild dont waste time and money faffing around

the coolant sensor in GM have the same color code for wire Black and yellow.Now coolant sensor is located on engine block or near thermostat.

There was a common fix for your car. Your ciera has a lock up torque converter when you go into opverdrive there is a wire connection on the side of your transmission it feeds power to a solenoid located on the valvebody, it is supposed to disengauge when you are comming down to a stop, if it does not it feels like you have a standard transmission in it and to forgot to push in the clutch. Try disconnecting the connector and drive it, if it does not stall you have found the problem.

I would try to have the transmission flushed and filled if not done within the last 30,000 mi. If this doesn't improve the condition for about $100 or so, then I would have it rebuilt or replaced.

You have to remove the steering wheel and the plate that is behind it with two screwdrivers. unplug the wire hareness to that. you will also have to remove the screws that hold you hazzard light button on and remove the bottom of the steering column. Tie a string or wire to the harness so you can pull that back thru the column whn you have to reattach the new one.

no you have a failed transmission on your hands, it is slipping.

internal trans part. should be in valvebody area.

On top of engine as your facing it, there should be what looks like a temp. sending unit with a 2 wire plug on it, chg. that, it sends a signal to trans. when it gets warm enought to shift to overdrive. If trans shifts fine but won't go into overdrive thats most likely the problem.
