It will depend on whether yours is an OBD system or not. OBD (On Board Diagnostics), didn't start to become a legal requirement until 1996 but some companies were fitting them earlier than that. First check your steering column for the green style connector on the attached image. If there is none like that, use a torch and get your head into the Driver's side footwell. Your looking for the black style connector, (red circle), on the attached image. It will be at about the height of the driver's knees at the door side. They are sometimes tucked up under the dashboard, out of sight, possibly behind a small flap or cover.
I hope this helps.

sadly the early version of the 4 speed is prone to this type of failure. I have owed 4 that had this exact problem. the rear end of the main transmission case wears down at the transfer case and this causes an internal leak. The loss of fluid pressure causes the loss of function. I'm confident that a good transmission shop can fix this by using a case and parts from a newer version of the 4 speed auto

Try removing the shifter cable from the shifter arm on the transmission . Remove the arm from the shaft on the transmission and position the arm 180 degrees and install it back on the shaft. reconnect the shifter cable to the arm and see what is does then. Outside of that I don't know.

Need to narrow down whether it's mechanical, as in a chipped starter gear or misaligned starter, or electrical connection. See if the starter solenoid is consistently getting power when you turn ignition key

How many miles do you have on the car? Are there any leaks? Are there any funny sounds when you try to start the engine? Any knocking sounds?

If this is a manual transmission you may have worn shifter parts. If it is an automatic you most likely will need an overhaul, most transmission repair shops give free inspections in hope they get the work of repairing what is wrong.

its behind the dash and its circular in shape. its hard to reach even with the lower panel removed but with a long flat screwdriver the bracket that mounts it can be popped open to gain access.
the clip/bracket is circular and has a tab that opens up

first link is for the legacy and the second shows the white clip

Check wheel bearing.
Check backing brake plate , sometimes it's bended and touching brake rotor.
If wheel bearing is bad , you may have same effect with backing plate , brake rotor touch backing plate.

The speed sensor is located on the transmission output . I don't think the problem is in the dash. Go to YouTube and type in where is the speed sensor on a 1991 subaru legacy and it will bring up all related videos. Hope you find this useful.

Remove the caliper and rotor, undo the axle, ball joint and the two strut bolts, and take the entire knuckle off. The hub is pressed off, then a circlip removed to press the bearing out. You need a hydraulic press to do this job.
