Take Full Control Of Your Duramax Shifts

If you're looking for that missing link in performance and drivability for your 2001-2005 Duramax, the ATS Co-Pilot Transmission Controller is your next smart upgrade. Designed to work in harmony with the 5-speed Allison 1000, this unit transforms your truck's shifting behavior by fine-tuning how and when your torque converter locks up. Whether you're towing heavy loads or just want a more connected feel behind the wheel, this system gives you smoother transitions and more confident acceleration. By syncing with your boost, throttle position, and vehicle speed, the Co-Pilot adds a whole new layer of responsiveness that you can feel immediately. It’s plug-and-play and tailored specifically to the Duramax platform, so you don’t need to be a wiring wizard to install it. You’ll notice right away how much better your transmission behaves under pressure, especially when you’re pushing your truck a little harder than stock. It’s peace of mind for your transmission and performance you can count on.

Engineered Precision That Talks Directly To Your Transmission

Behind the scenes, the ATS Co-Pilot is a highly responsive module that actively manages transmission pressure and torque converter lock-up based on real-time engine feedback. It pulls in signals from your MAP sensor, throttle position sensor, and vehicle speed sensor to create the optimal shift timing for every situation. Instead of relying solely on factory calibration, the Co-Pilot dynamically adjusts based on load and driving style, helping to minimize slip and excessive heat buildup inside your Allison 1000. That means less wear and tear on internal components and more consistent torque delivery. It’s particularly beneficial for trucks running modified tunes or upgraded turbos, where extra power demands more precise transmission control. The system is compact and integrates seamlessly into your engine bay, maintaining factory-like reliability while delivering aftermarket-level intelligence. With the Co-Pilot on board, you’re not just shifting gears, you’re shifting smarter.
