Transmission will not shift third to fourth gear

Have changed solenoids A and B.
Have checked specific gear change solenoids and have changed there location too. Check still no change from third to fourth not working.
When car try’s to change from third to fourth car revs out kicks back to third and then won’t try to change up to fourth after that until I turn off car then it will try to do change but revs out and changes back to third.
