Issue:
Customer may complain that –
1. Gearbox fault is displayed on the Instrument Cluster (IC)
2. Flashing ‘D’ on the Transmission Control Switch and/or
Instrument Cluster (IC) following an ECO Stop/Start event.
ONLY DTCs P0715-64 and P0700-02 are stored in the Transmission
Control Module (TCM).
P0715-64 - Input/Turbine Shaft Speed Sensor "A" Circuit - signal
plausibility failure
P0700-02 - Transmission Control System (MIL Request) - general
signal failure
If there are any other DTCs stored in the TCM they must be
investigated and rectified prior to carrying out the instruction detailed
in this SSM. Refer to the DTC index on TOPIx – 100-00 General
Information – Diagnostic Trouble Code Index DTC: Transmission
Control Module (TCM)
NOTE – The concern detailed in this SSM is applicable to 2017
and 2018 MY vehicles and typically occurs at low mileage (below
2500 miles/4000 kilometres) and affects vehicles fitted with the
8HP45 or 8HP70 automatic transmission.
Cause:
Error in the TCM software (adaption learn will permanently resolve the
concern if the issue is a TCM software error), or a fault in the
mechatronic valve block assembly installed in the transmission.

If ONLY DTC P0715-64 and P0700-2 are stored then using
Pathfinder clear the DTCs.
Carry out an adaption drive cycle using Pathfinder so that a
minimum of 3 counts are achieved for each clutch. Select ECU
Diagnostics – Transmission Control Module (TCM) –
Transmission control module adaption learn.
