Understanding Transmission Issues
Your truck's transmission is one of its most complex and critical components, responsible for transferring power from the engine to the wheels at the appropriate gear ratio. When transmission problems occur, they can seriously impact your vehicle's performance, fuel efficiency, and operational capability.
At MTS TruckAI Services, we specialize in diagnosing and repairing all types of commercial truck transmission issues. Our experienced technicians are skilled in servicing both manual and automatic transmissions across all major manufacturers, including Eaton, Fuller, Allison, Volvo, Mack, and more. From minor repairs to complete rebuilds, we provide the expertise needed to get your truck back on the road efficiently.
Our Transmission Services
Comprehensive Diagnostics
We utilize advanced diagnostic equipment to accurately identify transmission issues. Our detailed testing process includes computer diagnostics, road testing, and physical inspection to pinpoint problems with precision, saving you time and money on unnecessary repairs.
Transmission Repairs
From replacing worn synchronizers and bearings to addressing solenoid problems and hydraulic issues, our technicians can repair a wide range of transmission components. We source high-quality parts that meet or exceed OEM specifications for lasting reliability.
Complete Rebuilds
When transmissions require extensive work, our rebuild services offer a cost-effective alternative to full replacement. We disassemble, inspect, and replace worn components, then reassemble and test the transmission to ensure proper function and longevity.
Preventative Maintenance
Regular transmission service extends component life and prevents costly failures. Our maintenance includes fluid and filter changes, cooler line service, and inspections of seals, mounts, and linkages to keep your transmission operating at peak efficiency.

Customer Testimonials
When our fleet truck had transmission issues halfway through a cross-country haul, MTS responded quickly with mobile diagnostics. They were able to make the necessary repairs on-site, saving us from expensive towing and getting our driver back on schedule within hours.

I brought my truck to MTS after two other shops failed to fix the transmission issues. Their diagnostic process was thorough, and they found problems the others missed. The rebuild they performed was exceptional - 150,000 miles later and it's still shifting perfectly.

Frequently Asked Questions
The decision between repair and rebuild depends on several factors including the extent of damage, component availability, and cost considerations. Our diagnostic process will assess internal damage, fluid condition, and overall transmission health. Minor issues like solenoid failures, sensor problems, or external seal leaks can often be repaired individually. However, if you're experiencing metal contamination in the fluid, multiple gear failures, or extensive internal damage, a rebuild is typically more cost-effective long-term. We'll always provide both options when possible so you can make an informed decision.
A standard transmission rebuild typically takes 3-5 business days. The timeline includes disassembly (1 day), inspection and parts ordering (1-2 days), reassembly (1 day), and testing (1 day). More complex transmissions or those requiring specialty parts may take longer. For fleets and regular customers, we offer expedited service options and can sometimes complete rebuilds in as little as 2-3 days. During repair, we can often provide loaner units or coordinate rental options to minimize your downtime.
We service all major commercial truck transmission brands and models including Eaton Fuller (including UltraShift and AutoShift series), Allison (1000/2000/3000/4000 series), Volvo I-Shift, Mack mDRIVE, Detroit DT12, ZF Meritor, Spicer, and more. Our technicians are certified and experienced with both manual and automated manual transmissions (AMTs), as well as fully automatic transmissions. We maintain a large inventory of parts for popular models and have established supply chains for specialty components to minimize repair times.
Yes, we offer mobile diagnosis and repair for many transmission issues. Our service trucks are equipped to handle fluid changes, external component repairs, sensor replacements, solenoid work, and select internal repairs that don't require transmission removal. For more extensive work like rebuilds, we can arrange towing to our facility. In some cases, we can even perform transmission removals on-site and transport just the transmission to our shop for rebuilding, saving you significant towing costs. All mobile services are available 24/7 for emergency situations.
All of our transmission repairs and rebuilds come with a comprehensive warranty. Minor repairs carry a 90-day/10,000-mile parts and labor warranty. Complete rebuilds are backed by our 12-month/100,000-mile warranty (whichever comes first). For fleet customers, we offer extended warranty options up to 24 months. Our warranty covers all internal components and workmanship, and is honored nationwide through our service network. We use only quality OEM or premium aftermarket parts that meet or exceed original specifications to ensure reliability.
