Allison Transmission Expertise
Allison transmissions are widely used in commercial trucks, buses, emergency vehicles, and industrial applications. Known for their strength and durability, they still require specialized care to perform reliably over time. At American Transmissions, we are highly experienced in diagnosing and servicing Allison units, from fluid and filter maintenance to more complex repairs.
We handle concerns such as overheating, slipping, and hydraulic pressure issues while ensuring that each Allison transmission is serviced with manufacturer-approved fluids and procedures. Our team also provides rebuilds and replacements for units with extensive wear, restoring dependable performance for high-demand applications.
Heavy-Duty Transmission Service
Heavy-duty trucks and equipment put extreme stress on their transmissions due to towing, hauling, and frequent stop-and-go operation. These conditions accelerate wear on components, leading to overheating, fluid contamination, and premature failure if not addressed.
Our heavy-duty transmission services include fluid flushes, filter replacements, torque converter inspections, and full diagnostic checks. For vehicles experiencing major issues, we provide targeted repairs or complete rebuilds designed to restore strength and efficiency. By tailoring each service to the workload demands of heavy-duty vehicles, we help extend service life and reduce downtime.
Fleet Transmission Maintenance and Repair
Fleet vehicles are the backbone of many businesses, and unexpected transmission failures can cause costly interruptions. At American Transmissions, we provide fleet transmission maintenance programs that keep work vans, trucks, and specialty vehicles on the road.
Regular transmission fluid service, diagnostics, and inspections are scheduled to prevent breakdowns and extend the lifespan of each vehicle in the fleet. When repairs are needed, we prioritize quick turnaround times to minimize disruption. From delivery services to construction companies, our fleet solutions are designed to maximize reliability and reduce operating costs for Garden City and Roseville, MI businesses.
Common Issues in Heavy-Duty and Fleet Transmissions
While every vehicle is different, heavy-duty and fleet transmissions often experience predictable wear patterns. Some of the most common issues we repair include:
Overheating Under Load
Prolonged towing or heavy hauling can lead to excessive heat buildup and fluid breakdown.
Fluid Leaks and Contamination
Continuous operation often accelerates seal wear, causing leaks and introducing contaminants into the system.
Torque Converter Failure
High stress can cause torque converters to lose efficiency, resulting in poor acceleration and slipping.
Gear Slippage and Delayed Shifting
Inconsistent shifting under load often signals internal wear or hydraulic issues.
By identifying and resolving these problems early, we keep vehicles operating safely and efficiently.
