Car stalls then put in gear. Tune up did not solve problem.
95k miles. Vehicle starts every time, but sometimes stalls when up into gear. Will do this repeatedly until you give it a little gas and throw it in gear. Next time it may start and go just fine without stalling. Has tendency to hold in gear a little too long when you come to a stop. Ran the car at 50 mph for half mile and then stopped. Car stalled and would stall then restart but stall as described above, but once I got it going, it vibrated up through 20 mph where I shifted into neutral and back into gear and drove fine until I stopped at a light. This time after getting it started, it ran fine the rest of the way home, stops and all.

    Unplug the electrical connector at the front of the transmission, I believe it is a square plug or a round plug. This supplies power to the TCC solenoid inside the tranny. This solenoid fails and causes the stalling you are describing, especially if you notice the engine stalling as you approach a stop at a traffic light or stop sign. The fix is to replace the solenoid inside the unit. the temporary (or permanent if you want) is to unplug the connector and the solenoid will never become turned on so it cannot stick after that. The only downside is that the check engine light will illuminate and you now will not have that 'overdrive" feeling after you get up to speed. the torque converter will no longer go into "lockup". Most people usually like the result because the car will seem like it has more response at higher speeds. Unplugging the connector is a diagnostic tool to confirm this as the cause.

    Thank you for your suggestion will put it to the test. Was thinking it might be the VSS as a possibility, but this sound like a better solution. Thank You!
