1993 Ford Crown Victoria car cuts off

The transmission is probably not to blame the jerking was probably a misfire. Sounds like an engine problem.

Consider an OBD scan (Code Reading) With most problems like this the scan must be done. Todays autos are very complex (Not like the old days).
The whinning may be a failed starter (Not related to the original problem) Just over worked & old?
Try the scan & repost your question with findings. Please try to avoid terms like "cranks up" and "cuts off" these terms can be difficult to understand since the context can be confusing, consider terms like the engine quits, starting the engine. The better you articulate and proof read your posting the better we can give you good informed advice.
