My car went into. Limp mode due to the transmission seal needing to be replaced. So I was low fluid. I replaced it and added fluid but now when I shift to " D " the car stalles and dies.
My car has 186000 miles.
My car has an automatic transmission.

Several possibilities could account for this. The torque converter could be locked up. To get an "indication" of that possibility, you could try raising engine speed to around 1,800 RPM and then, with a clear and safe path ahead, put the gear selector in drive. Be careful, of course. If the engine stays running as the car lurches forward but then does go on to stall again once you brake and return to idle, that is a possible indication of a locked up converter. Putting it in gear at 1,800 is hard on the car’s drive train so don’t do this repeatedly. Another possibility is internal transmission seals are leaking pressure to reverse and forward clutches at the same time and the locked up transmission then stalls the engine. Defective engine sensors can cause this issue. The Manifold Absolute Pressure (MAP) sensor detects engine load and generates a signal that is proportional to the amount of vacuum in the intake manifold. The ECU uses this information to adjust ignition timing and fuel enrichment relative to the amount of power needed. When the engine is working hard, intake vacuum drops as the throttle opens wide and the engine takes in more air, which requires more fuel to keep the air/fuel ratio optimized. When the computer reads a heavy load signal from the MAP sensor, it adjusts the fuel mixture to slightly more rich than normal so the engine can produce more power. The computer will then retard (back off) ignition timing slightly to prevent detonation (spark knock) that can damage the engine and decrease performance. This may explain why the engine dies as you put the vehicle into gear as a load is put on the engine.
