Key features and benefits:
* Factory A40/A50 TCMs used in 2006-2015 GM Duramax trucks are notorious for failing due to delicate internal wires and high heat exposure from their mounting locations—ATS upgrade kits solve this by providing advanced hardware with upgraded, rugged processors.
* ATS offers a direct plug-and-play retrofit to replace obsolete A50 modules with the much faster T87A TCM (found on later-model Duramax trucks), this allows for faster, crisper shifting, better torque converter lock-up response, and full use of ECM exhaust braking
* Integrated Co-Pilot Technology—many kits come with ATS's proprietary Translator and Co-Pilot technology built into the assembly, this commands internal clutch timing and controls line pressure, allowing the transmission to handle higher power levels or oversized tires without premature wear
* Plug-and-Play installation—the kits feature OEM-quality wiring harnesses, meaning no permanent modifications to your truck's factory wiring are required
* Improved drivability and fuel economy—by keeping the engine operating within optimal RPM ranges and optimizing shift firmness, these kits deliver a more comfortable ride, better throttle response, and improved fuel economy
