Exact family and transmission type
Eaton Endurant family is a group of automated manual transmissions. This hub-like legacy slug now separates HD, XD and XD Pro instead of conflating them.
Versions and era boundaries
Identify HD 12-speed versus XD/XD Pro 18-speed before applying any specification.
Published ratings and architecture
No family-wide torque, GCW, reverse or PTO number is used here; follow the exact-model authority. Use the data sheet for the exact model; a family maximum does not establish the limit of the installed unit or truck.
Engine and truck relationships
OEM and engine availability varies by model year and approved application.
Tag, model-code and software verification
Use full tag/model code, factory build, software and clutch/control history.
Integration and later-swap cautions
Confirm factory relationship or document a later swap and its calibration.
Low-speed, grade and duty-cycle questions
Choose the exact family by highway, severe on-highway, vocational, low-speed and reverse requirements.
Service evidence and road-test scope
Request fluid/service records where applicable, clutch and actuator history for AMTs, control-module fault reports, calibration history and repair invoices. Evaluate engagement, shifts, reverse manoeuvring and warnings in a safe, suitable road test with qualified follow-up for abnormal behaviour.
Reviewed and verification limit
Reviewed September 4, 2026. Torque, gross-combination, PTO and application limits apply only to exact published models and configurations. This page is not a fitment or operating approval.
Endurant variant boundary
Endurant HD, XD or other published variants have different application contexts. Confirm the full tag, torque application and installed controls rather than applying one product sheet to every automated Eaton transmission.
Clutch, actuator and software evidence
Request clutch and actuator history, fault reports and calibration records. Test launch, low-speed manoeuvring, grade response and shifts under a suitable operating condition; a short unloaded drive may not expose application-specific behaviour.
Endurant and UltraShift PLUS boundaries
Both are Eaton automated-manual families found in the marketplace, but they are not the same transmission. Identify the complete model, torque rating, clutch and control system before applying maintenance guidance.
Verify the individual truck
Build information, component tags, service records, diagnostics and a qualified inspection take priority over general family-level guidance.
