Sorry for the confusion.
This car has been having an issue with RPM, specifically, it runs well until the RPMs get up to about 3K and then it get very lazy and maxes out at about 4K rpm at WOT. It will not shift at that point either, when I back off the throttle it will shift and runs good again unitl the RPM's get above 3K and the scenario plays out through all of the gears. The problem started intermittenly and has gotten progressively worse over the winter and now runs like this 95% of the time. At times, it will run normal and runs and shifts normally, it's like a switch gets turned on and then back off.
As I have been going through this I realized that the transmission is slow to go into gear in the morning. It has 200K miles on it and I am wondering now if the filter could be blocked or a solenoid sticking that can be causing this. I am thinking a solenoid would make more sense because when it does work right it is like a switch is turned on.
I have read about a spring in the valve body for the 1st to 2nd shift that breaks or gets weak and also about a " reluctor plate" that can be faulty but nothing that describes and issue similar to what i am seeing.

Thanks for any feedback
