    Sure you can change it...what you probably heard was that you shouldn't have an old transmission FLUSHED by a machine---which I agree with.


    Hard shifting can be due to many things--it's apparently a pressure problem---but what is causing it is hard to say---if it were a stuck valve/solenoid, perhaps that could be freed up with an oil change, but if the damage is internal, to the clutch pack, etc., then it won't do any good.

    Certainly worth a try. If that doesn't work, you might ask a qualified transmission shop to do a computer scan and/or external pressure testing.
