My car was shutting off as soon as you put it into gear. I believe that the torque converter lock out switch was replaced. Now it does not shut off, but after waming up to operating temp. And put into gear it makes clanging noises like it is trying to pump the fluid but can't. It also afects the idle slightly.

When you pull the dipstick, are there any traces of metallic particles?

Does the car drive okay?

I apologize for the questions but I don't want to assume anything.

There is a noise and a idle problem that does what?
(rough, high etc.) The noise only happens after it is warm

The stalling is gone when in gear now? What does it do before it reachs operating temperature?

Are there any codes in the computer?

I have seen cracked flywheels that can make the clanging noise.

No need to apologize. Only in gear it is a rough idle that drops and then comes back up, and only at warm temp, idles fine when cold. Yes the stalling is gone, before temp. Is reached it makes slight noise, not to bad. But is a lot worse after warming up. No, the computer is giving no codes.

Ok. The idle speed is controlled by a few different inputs. A temperature related one is the coolant temperature sensor (CTS). IT gives the pcm info and an adjustment is made at the throttle by the IAC idle air control motor.

Get it to operating temperature, shut it off, key off. Pull the harness of of the CTS and measure the resistance.
At 200 degrees the sensor should be between 700-1000 ohms. IF not replace it. IF it is good, remove the IAC and clean it with intake cleaner. The pintle may be sticking.

The car needs to be accessible from the bottom to diagnose the noise. A stethescope can be used to narrow it down. Again, it may be a cracked flywheel.
