The Tundra automatic transmission (ATM) issue was delayed due to a midprocess specification change that delayed the completion of the final software specifications. Both the Camry and Sequoia issues were also delayed due to unforeseen design approval issues. All three issues suffered delays during the final countermeasure deadline. This step is such an important milestone that it can cause all other dependent milestones to be delayed as well. For example, the engineering change documents cannot be processed without the final countermeasure approval. In all three issues, the cause for the delay was identical. Further monitoring is planned to determine if there is a sufficient amount of time allotted for the completion of this step.
