4T80E

The 4T80E is a four-speed automatic transmission with longitudinal layout, developed for front-wheel drive Cadillac vehicles equipped with Northstar V8 engines. The design incorporates two Simpson-type planetary gearsets. Filter replacement requires removal of the oil pan—external access is not available. Characteristic differential satellite gear wear is known, often resulting in differential case failure after 160,000–220,000 km.
