TRANSMISSION RANGE SENSOR
- Place transmission range selector lever in "N" position. Remove shift control lever. Loosen Transmission Range (TR) sensor retaining bolts. Install Transmission Range Sensor Alignment Tool (307-415). (Scheme 13) Tighten TR sensor retaining bolts to 89 INCH lbs. (10 N.m). Install shift control lever, and tighten nut. Tighten all nuts and bolts to specification. See «TORQUE SPECIFICATIONS»(ref-168168-S12516468432004110200000).
- Check for park gear engagement. Start engine and ensure indicated gear positions match transmission response. If operation is not okay, check shift cable adjustment. Verify vehicle only starts in Park and Neutral positions, and back-up lights operate.

SYSTEM TESTS
| CAUTION | Before testing starter, ensure transmission is in Park (A/T) or Neutral (A/T or M/T) position. |
| Symptom | Perform Test |
|---|---|
| Starter Does Not Crank But Relay Clicks | A |
| Starter Does Not Crank & Relay Does Not Click | B |
| Starter Cranks Slowly | C |
| Unusual Starter Noise | (1) |
| Starter Motor Spins But The Engine Does Not Crank | (1) |
| (1) Inspect starter motor mounting. Inspect flywheel ring gear and starter motor gear for damaged and missing teeth. Repair or replace components as necessary. | |

SYMPTOM INDEX
STARTER RELAY
- Remove starter relay from central junction box. Check relay continuity. Continuity should exist between relay terminals No. 85 and No. 86, and between relay terminals No. 30 and 87a. (Scheme 14) Continuity should not exist between relay terminals No. 30 and 87. If continuity is as specified, go to next step. If continuity is not as specified, replace relay.
- Using a jumper wire, apply battery voltage to relay terminal No. 85. Using a second jumper wire, ground relay terminal No. 86. Continuity should now exist between relay terminals No. 30 and 87. If continuity is not as specified, replace relay. If continuity is as specified, relay is okay at this time.
