Transmission light is on wont shift out of park. Tach jumps Engine stalled on 1995 Jaguar Vanden Plas

It first started with the transmission. It would have to run and idle for a minute before it would shift out of park. Now it wont shift out of park at all and the tach. jumps up and down. The engine will then stall and wont start. The fluids are up and the trans. did not slip prior to this problem.
