"reverse pressure switch" , I havent heard this term b4 . I think they are referring to either the brake switch to solenoid pack... bth are cheep and ez to fix yourself.Only reason I say solenoid pack is because that IS what controls your tranny fluid pressure when changing gears and since they mentioned the forward gears going out as well this would make sense. I would swap out solenoid packs and see what happends. What yr is your car? You may want to pick one up for a caravan. This is considered an upgrade and will get rid of that nasty buzz noise when u put it into reverse.
