Exact family and transmission type
Eaton Cummins Endurant XD is an 18-speed automated manual transmission for severe on-highway and vocational use. It is separate from HD and from XD Pro.
Versions and era boundaries
Identify XD model/design level and do not import XD Pro crawler or application claims.
Published ratings and architecture
Torque, GCW, reverse and PTO specifications must come from the exact XD publication. 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
XD is available only in approved engine/OEM/application combinations.
Tag, model-code and software verification
Capture model tag, software, clutch/actuator history, factory build and published approval.
Integration and later-swap cautions
Check engine torque, driveline, axle ratio, PTO and chassis electronics.
Low-speed, grade and duty-cycle questions
Compare heavy startability, grade, reverse, soft-surface and mixed highway/vocational work.
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.
Verify the individual truck
Build information, component tags, service records, diagnostics and a qualified inspection take priority over general family-level guidance.
