(P0730) IMPROPER GEAR (CONTINUED)
When Monitored and Set Condition
• When Monitored: Engine speed greater than 450 RPM and output speed (ABS) greater than 180 RPM. No
Input Speed sensor N2 - N3, Shift lever, and/or ABS wheel speed DTCs present.
• Set Condition: The TCM compares the calculated gear with the gear the transmission has actually engaged. If
the actual gear differs from the gear calculated by the TCM, the TCM value is adjusted to the engaged gear
and a counter is increased by 2. If after a shift the engaged gear and the calculated gear still match, the
counter is decreased by 1 point. A DTC is detected as soon as the counter exceeds a threshold. If the fault is
detected 3 consecutive ignition cycles, the transmission will be placed in Limp-in and the MIL activated.

Diagnostic Test
1.
PRE-DIAGNOSTIC CHECK OUT
Note: Low fluid level can be the cause of many transmission
problems. If the fluid level is low, locate and repair the leak then
check and adjust the fluid level in accordance with the Service
Information.
Note: Always perform diagnostics with a fully charged battery to
avoid false symptoms.
With the DRB III , read Engine DTCs. Check and repair all engine
DTCs prior to performing transmission symptom diagnostics.
With the DRB III , read and record all Transmission DTCs.
Note: Check connectors - Clean/repair as necessary. Poor pin to
terminal connections can set DTCs.
Using the wiring diagram/schematic as a guide, inspect the wiring and
connectors. Repair as necessary.
Most DTCs set on start up but some must be set by driving the vehicle such that all diagnostic monitors have run.
Note: Check for any Technical Service Bulletins that may apply.
Perform this procedure prior to Symptom diagnosis.
