Introduction
Some 2017 – 2018 model year Highlander and Sienna, 2018 model year Camry, and 2019
model year Avalon vehicles with and without the stop and start feature may exhibit a flex lock-up
concern and MIL ON with Diagnostic Trouble Codes (DTCs) P07407E and/or P27567F. Vehicles
that have experienced a delay in engagement from R to D will experience flex lock-up concerns
from loss of solenoid pressure. The Engine Control Module (ECM) (SAE term: Powertrain Control
Module/PCM) logic has been modified to reduce the possibility of this condition. Follow the
Repair Procedure in this bulletin to address this condition.
NOTE
For Highlander, Sienna, and Camry model vehicles a Mismatched transaxle assembly hardware and
ECM (PCM) software combination may result in a harsh shift or shift flare. If this occurs after the original
repair, additional ECM (PCM) replacement and reprogramming will be required.
