* Commanded Gear is 1st locked.



* Gearbox Slip is 200 RPM up or greater for 3 seconds.



* If above conditions exist, the TCM will command second range. If the gear ratio is between 2.7 and 3.0 for 1 second, the counter will



increment, and the DTC will set after 5 occurrences.



Action Taken When the DTC Sets



* DTC P0756 is a Type A DTC.



* The TCM inhibits Tap Up/Down function.



* The TCM inhibits manual shifting of forward gears.



* The TCM commands maximum line pressure.



* The TCM freezes transmission adaptive functions.



* The TCM limits the transmission to reverse, first, and third range operation.

Circuit/System Verification



Note: If other DTCs are set, diagnose those DTCs first.



1. Perform the Transmission Fluid Level and Condition Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing



and Inspection/Component Tests and General Diagnostics/6T70/6T75 - Automatic Transmission/Transmission Fluid Level and Condition



Check) to verify correct fluid level and condition.



Note: Perform a scan tool snapshot, during the road test.



2. Perform the Road Test (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Initial Inspection and



Diagnostic Overview). Verify the transmission operation performs as indicated, in the road test instructions.



3. Review the scan tool snapshot transmission data parameters. Verify the engine and transmission data parameters display the correct values in



all forward gear ranges:
