Exact family and transmission type
Mack mDRIVE is an automated manual transmission family integrated with Mack powertrains. HD/Severe Duty, crawler and multi-speed descriptions require exact model evidence.
Versions and era boundaries
Separate legacy MP8-era mDRIVE from revised MP13-era integrations and identify the full transmission model.
Published ratings and architecture
Speed, crawler, torque, GCW and PTO claims must come from the exact Mack data sheet. 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
mDRIVE appears in qualified Anthem, Pioneer, Pinnacle, Granite and announced Keystone configurations by era and application.
Tag, model-code and software verification
Verify tag, control software, clutch/actuator history, shift program and truck build.
Integration and later-swap cautions
Confirm MP8/MP13 relationship, axle ratio and PTO programming; a swap requires documented electronic and mechanical integration.
Low-speed, grade and duty-cycle questions
Regional starts, highway cruise, severe-duty low speed, grade and reverse work may favour different variants.
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.
