Allison Transmission Service at Riley Auto Care
Allison transmissions are the heavy-duty choice in GM Duramax-powered trucks and commercial vehicles. The Allison 1000 and 2000 series are found in Silverado HD, Sierra HD, Express vans, and medium-duty trucks. The newer 10L1000 is Allison's 10-speed unit for the latest generation of heavy-duty GM trucks.
These transmissions are built for durability, but they still require proper maintenance and can develop issues — particularly around solenoid wear, valve body problems, and fluid degradation from heavy towing or commercial use.
