transmission disengaging after serring and cool it engaged turned off, restarted would not engage. no leaks and fluid level OK.
I have no idea what that means . But since very few people can repair their own automatic transmissions it seems that you should find an independent transmission shop.
If you have a friend, neighbor, or relative whose native language is English, I urge you to have that person re-post your problem. At this point, I doubt if many people will be able to understand what you are trying to communicate to us.
Transmission diagnosis is best left to professionals, and that doesn’t include the charlatans at the chain-run transmission shops.
Do you mean “after sitting”? That would make some sense and give folks a hint. Find a good transmission shop and have it looked at.
