I assume this cannot be installed with the tranny in the car?


Yes it can, pull the valve body and do it on the bench , re install the valvebody. The part you are replacing is the shift(manual) valve , it allows more fluid flow in park than the stock valve does.

So does this also make the tranny a manual shift only ? thanks for the info. Approximate cost and where to get?
