Product Description
Allison Automatic Transmission Assembly 4700RDS Allison Rugged Duty Series
The Allison 4700RDS is a heavy-duty automatic transmission designed for on-highway vocational applications, particularly refuse trucks, dump trucks, and specialized hauling vehicles. It is part of Allison’s 4000 Series, known for robustness, high torque capacity, and PTO (Power Take-Off) support.
Key Features of the Allison 4700RDS
✔ 6-Speed Automatic – Optimized for heavy loads and stop-and-go operations.
✔ High Torque Capacity – Handles up to 1,650 lb-ft (2,237 Nm) input torque, making it ideal for large diesel engines (e.g., Cummins X15, Detroit DD16).
✔ RDS (Road Duty Series) – Designed for on-highway severe-duty cycles (e.g., garbage trucks, concrete mixers).
✔ PTO Support – Multiple PTO options for hydraulic pumps, compactors, or auxiliary equipment.
✔ Electronic Controls – Uses Allison WTEC IV or Advanced controls for smooth shifting and diagnostics.
✔ Lock-Up Clutches – Improves fuel efficiency by reducing torque converter slippage.
✔ Durable Construction – Reinforced gears and housing for high-stress environments.
Common Applications
Refuse/Trash Collection Trucks (e.g., Heil, McNeilus rear loaders)
Dump Trucks & Mixers (e.g., Mack Granite, Peterbilt 567)
Heavy Haul & Vocational Trucks
Emergency Vehicles (e.g., mobile command units)

Maintenance & Service Tips
Fluid & Filter Changes: Use Allison TES-668 or C4 fluid; replace every 25,000–50,000 miles in severe service.
PTO Operation: Ensure proper engagement to avoid transmission damage.
Shift Quality Issues: Check for software updates or solenoid malfunctions.
Overheating: Inspect cooler lines and radiator in high-load cycles.
Assembly & Rebuild Considerations
Gasket & Seal Kits: Use OEM parts for rebuilds (e.g., Allison 29548973 kit).
Torque Converter: Must match engine output (e.g., 18-inch vs. 20-inch).
Output Shaft: Verify compatibility with rear axle/PTO setup.
