Modern diesel engines rely on complex after-treatment systems to meet strict emissions standards—and when those systems fail, performance and compliance both suffer. G & T Truck Repair provides advanced after-treatment diagnostics to keep your trucks running clean, efficient, and trouble-free.
Our technicians use specialized diagnostic equipment to test and service DEF systems, DPF filters, SCR components, sensors, and electronic controls. We pinpoint the cause of warning lights, regeneration failures, and power loss, then make precise repairs or replacements as needed.
Whether it’s routine maintenance or troubleshooting a recurring fault code, we’ll help you restore full emissions function and avoid costly downtime or regulatory penalties.
