What? No more help form the expert????
Is this all I get?
I've told you my opinion......based on your description.........and all you have done is tell me that I am wrong and you know better.......so I choose not to pursue this.
I'm going to opt out and another expert might pick this question up and try and assist you.
I would have to agree with the last expert on this one. If you have a high pitch sound that says to me that your pump is starving for oil and is causing it to slip. I don't want to be insulted like the last expert was so if you coose to insult me I will close this question.
This will not be caused by a sensor or control module. If it is slipping in second and third according to the fault codes you listed it will not be a sensor or control. Sensors do not cause slippage, if bad they will cause the transmission to go into limp in mode which is second and reverse gear only. You will have to remove the trans for repair! There will be damage to your underdrive clutch.
I have run into problems like this before and what I have found was the filter gets plugged with torque converter clutch material when it fails and it will cause the pump to starve for oil(that is where the noise comes from) It is usually ok for a little ways until the filter becomes restricted then it makes the noise and when you shut the car off the oil draining back will wash the filter out a little and be good for a little ways again.
Why don't you pull the pan off and check the filter and inside the pan for excessive clutch material or even flakes of it and let me know. I won't click on answer until we find the problem so you won't have to pay until we found the problem. Let me know, thanks!
