When you rev it up and it finally goes into gear, does it shift OK after that? Sounds like a sticking pressure regulator valve. Please advise.

Yes after I rev it up and it clunks into gear it shifts fine I just have to repeat the process any time I drive it. Its that something that can be removed in the car if it has to be replaced?

The pressure regulator is serviceable by removing the trans pan. A trans service shop would have equipment needed to pressure test the system and varify the problem as pressure. Hope this helps.
