1995 Rodeo Transmission Problem

1. Transmission is stuck in 1st gear

2. Ammeter shows rise with rpm increase

3. Stall when comes to a complete stop

4. AC/Heat fan doesn't work

5. Changed transmission fluid, didn't help, old fluid looked good.

I have read that these issues might be related.

Alternator?
Voltage Regulator?
Range Mode Sensor?

Any Ideas?
