1, 2 and 3 Digit Codes: 70

Name of Code:
70 - Autostick Input Circuit

When Monitored:
Whenever the engine is running.

Set Condition:
1. The transmission shift lever is not in AutoStick and either the upshift or downshift switches are closed.

2. Both the upshift and downshift switches are closed at the same time.

Theory of Operation:
In the AutoStick Mode (manual shift mode), upshifts and downshifts are actuated manually. Shift requests are detected by monitoring the upshift and downshift switches. The Transmission Control Module (TCM) monitors the above set conditions. A set condition will be tolerated for up to 15 seconds before setting a code.

Transmission Effects:
- 96 MY - All AutoStick applications - The "3" position shift schedule that is used in non-autostick applications is substituted while operating in the autostick gear selector position. No limp-in mode occurs.

- 97 MY - All AutoStick applications - The "OD" position shift schedule is substituted while operating in the autostick gear selector position. No limp-in mode occurs.

Possible Causes:
- Wiring or connector problems
- AutoStick switch failure
- Defective TCM
