Product Description
Allison Automatic Transmission 4500PRM
The Allison 4500PRM is a specialized automatic transmission designed for permanent magnet (PM) motor-driven electric vehicles (EVs) or hybrid applications,
particularly in heavy-duty, off-road, and vocational markets. It is part of Allison's electric-hybrid propulsion lineup, combining traditional transmission durability with electric motor integration.
Key Features of the Allison 4500PRM
✅ Electric-Hybrid Ready – Designed to work with permanent magnet (PM) electric motors for hybrid or fully electric drivetrains.
✅ 6-Speed Automatic – Optimized gear ratios for efficient power delivery in electric/hybrid setups.
✅ High Torque Handling – Supports up to 1,250 lb-ft (1,695 Nm) input torque (similar to conventional 4500 models).
✅ Integrated Motor/Transmission Design – Compact layout for seamless electric motor pairing.
✅ Regenerative Braking Support – Recaptures energy during deceleration to recharge batteries.
✅ PTO (Power Take-Off) Capability – Maintains compatibility with hydraulic pumps and auxiliary equipment.
✅ Electronic Controls (Allison eGen Flex™) – Advanced software for managing electric motor & transmission coordination.
Common Applications
Electric/Hybrid Mining & Construction Trucks
Electric Refuse/Utility Vehicles (e.g., garbage trucks, sweepers)
Hybrid Military & Defense Vehicles
Electric Buses (if adapted for high-torque needs)

Maintenance & Considerations
Reduced Wear – Fewer moving parts vs. diesel transmissions (no torque converter slippage).
Battery/Inverter Compatibility – Must pair with compatible high-voltage systems.
Software Updates – Critical for optimizing motor/transmission interaction.
