Transmission Repair
Gillece Transmissions provides comprehensive repair services for automatic and manual transmissions in foreign and domestic vehicles. Our certified technicians diagnose issues ranging from leaks to internal failures, using state-of-the-art scanners and test equipment. Repairs include replacing worn parts, seals, and gaskets, ensuring optimal performance. With two dyno-testers, we verify functionality before installation, backed by a nationwide warranty. Our team prioritizes cost-effective solutions, often identifying non-invasive fixes to avoid full rebuilds.
Transmission Rebuilding
Our transmission rebuilding process involves complete disassembly, cleaning, and inspection of components. Worn or damaged parts are replaced with quality replacements, including torque converters, clutches, and seals. Reassembled units undergo rigorous dyno-testing to ensure proper shift timing, pressure, and durability. This service extends the life of high-mileage vehicles and restores performance for damaged transmissions. Rebuilds are supported by a standard 12-month/12,000-mile warranty, with extended options available, ensuring long-term reliability for cars, trucks, and commercial vehicles.
Diagnostic Services
Gilleces diagnostic services identify transmission issues through advanced computer scanning, fluid pressure checks, and sensor testing. Our technicians analyze error codes and perform road tests to pinpoint problems like sensor failures or internal mechanical faults. This precision approach prevents unnecessary repairs, saving time and costs. Diagnostics are conducted by ASE-certified specialists who provide clear explanations of findings, ensuring clients understand required repairs before authorizing service.
Fleet Maintenance
Gillece offers tailored fleet maintenance programs for businesses with multiple vehicles, including trucks, buses, and vans. Services include scheduled inspections, transmission fluid changes, and emergency repairs. Our large facility stocks critical parts for rapid turnaround, minimizing downtime. Fleet clients benefit from competitive pricing, dedicated account management, and priority service. With expertise in heavy-duty transmissions, we support industries ranging from logistics to municipal services, ensuring operational efficiency for commercial fleets.
Torque Converter Services
Torque converters are critical for automatic transmission function, transferring engine power hydraulically. Gilleces specialists rebuild or replace faulty converters, addressing issues like stall speed inefficiencies or fluid leaks. Our remanufacturing process includes replacing turbines, stators, and seals to restore smooth power delivery. Each unit is tested for balance and performance, ensuring compatibility with specific vehicle models. This service improves fuel efficiency and prevents transmission damage caused by converter failure.
