This question implies a lot of knowledge and suggests that the questioner already knows the answer. If the stalling occurs when you are slowing down to say come to a stop, then being in overdrive would stall the engine just like forgetting to push the clutch pedal on a std xmsn car. You are locked into overdrive. Overdrive is achieved by solenoid action in the tranny. If the solenoid is not automatically disengaging like it should when one slows down, then stalling will occur. If shifting manually to lower gears as one slows helps then the solenoid is probably sticking. Try disconnecting the solenoid wire at the connector at the front of the tranny, accessible from front of the vehicle with the hood up. Just reach down and separate the connector wires and then drive the car to see if this stops the problem. You can run this way w/o harm or open the tranny and replace the solenoid. You will just lose a couple mpg w/o overdrive. I think it can be replaced w the tranny still in the car, not sure.

I had a 1987 Chevy Celebrity that would start and then immediately die. It turned out to be bad fuel injectors. I replaced three fuel injectors and the problem has not returned.
Not enough air in the fuel
The Chevy 2500 HD Duramax would stall out at 200 RPM because of mechanical failures. The mechanical failure will make it not operate at its optimum.?æ
If your 1997 Chevy diesel will not shift into overdrive, you might have an issue with a transmission sensor. Some of these vehicles have several sensors that must engage in order to shift.
Automatics would include th350, th400, or the 700r4, if you want a overdrive.
If the Chevy Celebrity radiator is smaller that the Saturn radiator it might well overheat from not enough cooling capacity. If the Chevy Celebrity radiator is the same size or larger than the Saturn radiator I would think it would not over heat.
I have not seen a standard Chevy Celebrity with a toggle switch under the dash. I would suspect that is something a previous owner installed.
To answer your question I would need to know the year of your Celebrity as well as which one of the four transmissions it has.
I would think that on size alone it would fit and mount in. Depending on which of the engines the 1985 Celebrity had you might need to make a number of modifications to use the Corsica engine in the Celebrity. The two engines are NOT identical.
a vac leak
I would suspect fuel pump failure.
I would need to know the year and engine type to answer this question.
