Allison Specialists
Allison fully-automatic transmissions run in vocational, refuse, bus, and medium-duty trucks where smooth, durable shifting matters. We diagnose TCM faults and shift-solenoid problems, perform the fluid and filter service these units depend on, and handle overhauls when
they’re due.
Keep your Allison-equipped trucks shifting clean diagnosis, service, and repair under one roof.
