NOTE: There are a small number of trial run transmissions within the affected serial number ranges assembled with anodized TIDB main valve bodies in the factory or converted to TIDA in the field.

NOTE: Anodize implementation dates for 6-speed and 7-speed models were not simultaneous. As a result, eligible serial number ranges between those models differ.
