Frequently Asked Questions

Does this flexplate fit 2001-2004 Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500, GMC Sierra 2500 HD, GMC Sierra 3500?
Those are the verified vehicle applications. Also confirm 6.6L Duramax, production split, factory equipment, and every ATS application note before ordering.

Why must the transmission match this flexplate?
The crank pattern, converter pattern, starter position, balance, tooth count, and transmission family must match. A similar-looking flexplate is not proof of compatibility.

Are new flexplate bolts required?
Follow the current ATS and vehicle procedures for bolt replacement, thread preparation, torque sequence, converter spacing, and runout. Do not reuse torque-to-yield hardware where replacement is required.

Installation Instructions

Use the current ATS Diesel instructions and vehicle service information. Verify the exact application, required tools, fasteners, seals, fluids, calibration, torque values, clearances, and startup or relearn procedure. Professional installation is recommended for internal transmission, turbocharger, fuel-system, and driveline work.

Flex Discs

Flex Discs

Flex discs, also called guibo couplings, are the rubber-reinforced fabric driveshaft couplings used on rear-wheel-drive and all-wheel-drive vehicles with transaxle layouts to connect the driveshaft or propeller shaft to the transmission output flange, absorbing torsional vibration and minor angular misalignment between the gearbox and driveshaft while transmitting full drivetrain torque without the vibration penalty of rigid shaft coupling. These components are particularly common on BMW, Mercedes-Benz, Volvo, Porsche, and other European rear-wheel-drive platforms where the guibo design has been standard for decades, and worn flex discs are one of the most frequently overlooked causes of drivetrain vibration, clunking on throttle application, and accelerated universal joint wear on vehicles where the flex disc has hardened or cracked from age. Replacement with a quality rubber flex disc restores smooth power delivery and protects the driveshaft's universal joints from the shock load...

Flexplates

Flexplates

Flexplates are the thin stamped steel or billet aluminum rings that connect an automatic transmission-equipped engine's crankshaft to the torque converter, serving the dual function of providing the ring gear teeth that the starter motor engages for engine cranking and creating the flexible coupling between the rigid crankshaft flange and the torque converter's fluid-driven impeller housing. Unlike the flywheel used with manual transmissions, a flexplate is intentionally designed to flex slightly to absorb minor dimensional misalignment between the crankshaft centerline and the torque converter mounting face, preventing stress concentration at the crankshaft flange. High-performance SFI-certified flexplates are required by NHRA and IHRA for automatic transmission-equipped competition vehicles where the rotating assembly mass and launch forces exceed the safe limits of stock stamped steel flexplates. This collection covers replacement and performance flexplates for domestic and impor...
