Scenario...

1994 Nissan Sentra automatic XE model, 120k miles.

Friend mashed it to pull out in traffic and the car just stopped. It will not move in D1-4. It will move in reverse. Fluid level, color, etc. is good. No metal shavings, etc. No check engine light. No D4 light. No fluid leaks, etc. Engine runs good. No leaks, etc.

Any insight? Service manual to start trouble shooting?

Thanks.
