"D" Range Test
- Shift into "D" range. Hold accelerator pedal constantly at fully closed throttle position. Check 1-2 and 2-3 upshift points. See appropriate SHIFT SPEEDS table. Stop vehicle. If no 1-2 upshift occurs, 1-2 shift valve, 2nd brake solenoid, PCM or circuit is defective. If no 2-3 upshift occurs, 2-3 shift valve, direct clutch solenoid, PCM or circuit is defective.
- Operate vehicle at 15 MPH. Release accelerator completely. After 1-2 seconds, depress accelerator pedal fully. Check if downshift occurs from 2-1. Operate vehicle at 47 MPH. Release accelerator completely. After 1-2 seconds, depress accelerator pedal fully. Check if 3-2 downshift occurs. If no 2-1 or 3-2 downshift occurs, throttle position sensor, PCM or circuit is defective.
