Tranny causes engine to stall when tranny warms up

Your torque convertor will stop the engine stalling.

gas or diesel..

Should be on or near the fuel injector supply rail.

Replace the Torque Converter Solenoid in
the transaxle

What you have is like coming to a stop with
a manual shift & not pushing in the clutch & it stalls
the motor

The converter clutch is staying locked & your
trans is connected to the motor

Engine stalls or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Hi, car stalling problem often means the engine is not getting enough fuel and/or too much air. A cold engine needs a fairly rich fuel mixture to start, and to idle smoothly while it warms up. Any of the following could cause or contribute to this kind of stalling problem which i would not want to exaggerate until i get a clear picture of how the car stalls.

Does your engine stalls when you stop for a traffic light or when idling, or your engine just stalls unexpectedly while driving?
Answering the question will help me determine the cause of the problem.

Has the check engine light came on. Sound like a O2 sensor. But you can have the codes read for FREE at any Advance or Auto Zone Store. Hope this helps.

If the car is running that bad the check engine light should be on and code/s stored in the pcm along with a snapshot of what is going on at the time the code is set. A possible solution is to check the Mass Airflow Sensor or the MAP (manifold absolute pressure) sensor depending on which your vehicle is equipped with. The engine may run until the engine computer switches to closed loop fuel control (means its warmed up and the pcm is in control of the fuel trim) and then stall upon accel. Be sure you have checked all the basics first.

there are 2 things that usually cause this, one is a dirty intake idle control valve and the other is hard engine mounts, I would say that both most likely apply to your car. try cleaning the intake with the following procedure from Ford.
Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

yes it can but you may have a coolant temp sensor acting up which causes the computer to open the injectors to much which can also cause this 02 sensor code. when it stalls do u have spark and fuel pressure.
