Stuck in Mexico & car stalled, changed crankshaft position sensor but not care will not go in gear to get out of shop. Now they say transmission pump is bad. Is there even a trans. pump? or am I getting screwed? Can changing cam sensor break trans?

What is your question?

They have had my car for 47days now and after crank sensor repair the car started and ran but would NOT go into gear (Automatic Trans) and now they say it's the transmission pump. I can't even find that the car has a specific transmission pump. I think they screwed up and just want more money. Any help is wonderful!! Thanks, "Stuck in Mexico"
