AODE 4R70W 4R70E 4R75E Update Handbook – ATSG

Other Transmission

Since the introduction of the AOD-E transmission in model year 1992, there have been many major engineering design changes to improve durability and reliability. These changes have affected nearly every part used in the AOD-E, including two name changes, 4R70W and 4R75E. This “Update Handbook” will explain each change, the parts affected by the change, and any parts interchangeability concerns created by the change.
