I'm assuming you have the 4-speed automatic transmission rather than the 5-speed auto which apparently was an option.

The Digital Transmission Range (DTR) sensor is located on the driver's side (in US) of the transmission, about halfway between the bell housing and the tail shaft, just above the transmission pan.

If you have access to a profession scan tool with the datastream mode, you can use the scan tool to determine if the DTR sensor is registering the correct gear.

If you'd like a PDF version of the DTR sensor test procedure from the factory service manual, private message me with the request and an e-mail address for you that can accept attachments.

As for the horn and cruise control not working, they both use the clockspring assembly in the steeering column. If the horn clockspring is open, the speed control will never be able to turn on. The power for "On" is provided through the horn clockspring, and if the horn button is pressed, the "On" signal goes to ground and deactivates according to the wiring diagram. Likewise, if the horn/cigar lighter fuse is blown, I guess you'll never be able to turn the speed control "On" (fuse 10 in the Battery Junction Box).
