In order to improve the quality of the original equipment manufacturer (OEM) and service
replacement parts, Isuzu now requests dealers to capture TCM Freeze Frame Data for
all Aisin A465 6-speed transmission component parts replaced under warranty.

The primary purpose of the TCM Freeze Frame Data is to obtain faster and more accurate
quality information on all Aisin A465 6-speed transmission replaced components. The
collected information will be used to improve the reliability of OEM and service
replacement transmission components.
