V8 auto won't go in gear

[Zsolt]

Further to my ex car which seems to be in the wrong shop. They finally
found why they couldn't start the car after replacing the timing belt.
Naturally they did not use the retaining plates and managed to broke a
reference pin on the flywheel.

To get it replaced, they pulled the tranny back to get to the flywheel.
Now the car starts, but wont go into gear. They think the tranny pump is
malfunctioning. I think that is retarded and they probably screwed
something else up in the process of moving the tranny.

Any thoughts?

Thanks in advance,
