This Stage 6 package includes the torque converter, transmission controller, and wiring harness. The advertised flash stall rating is listed at 1,300–1,500 rpm, which should be confirmed against the vehicle’s engine output, use case, tire size, axle ratio, and towing or performance requirements.

The transmission is lockup compatible and features a deep aluminum pan with a black finish, 300M input shaft, and OEM-style aluminum case with a purple finish.

The flexplate is not included, the transmission cooler is not included, transmission fluid is not included, and the dipstick is not included, so buyers should confirm all supporting components before installation.

Fitment and Application Details

The ATS Diesel Performance 309-963-4332 Stage 6 automatic transmission package should be matched carefully to the intended Chevy diesel application before ordering. Automatic transmission compatibility can vary by vehicle year, model, engine, drivetrain, original transmission, torque converter setup, electronics, flexplate requirements, cooler routing, transmission mount, crossmember position, driveshaft/yoke setup, and installation hardware.

Important fitment details to confirm include vehicle year, make, model, engine size, engine code, drivetrain configuration, original transmission family, Chevy bellhousing bolt pattern, torque converter compatibility, 1,300–1,500 rpm stall suitability, flexplate compatibility, converter bolt pattern, crankshaft pilot fitment, controller compatibility, wiring harness requirements, electronic connector compatibility, lockup-control setup, transmission mount location, crossmember position, driveshaft length, yoke requirements, cooler line routing, transmission cooler requirements, fluid specifications, dipstick setup, and installation hardware.

The torque converter is included, and ATS Stage 6 packages may include a TripleLok or triple-patented Five Star torque converter, depending on the application. Buyers should confirm the exact converter supplied with this part number before ordering.

The transmission controller is included, and the wiring harness is included, but buyers should still confirm the correct control setup for the intended vehicle and engine application.

The flexplate is not included in the listed specifications, even though Stage 6 package features may include a billet flex plate depending on application. Buyers should confirm whether the correct flexplate is required separately for this exact model before purchase.

The transmission cooler is not included, so a proper cooling setup should be planned for towing, hauling, racing, high-power diesel use, fleet work, and heavy-duty driving.

For a complete installation, additional components may be required, including a flexplate, transmission cooler, cooler lines, transmission fluid, dipstick, sensors, mounts, crossmember hardware, driveshaft/yoke components, seals, wiring accessories, and vehicle-specific installation hardware.

Build Quality and Reliability

The ATS Diesel Performance Stage 6 Automatic Transmission Packages 309-963-4332 is built for diesel applications where torque capacity, internal durability, shift control, and power transfer are critical. ATS Stage 6 automatic transmission packages are designed to comprehensively address stock transmission weaknesses and create a stronger transmission package for towing, daily driving, or racing.

This package uses an ATS extra-deep, finned transmission pan for added cooling power. The listed specifications also confirm a deep black aluminum pan, giving the transmission added appeal for heavy-duty use where heat management matters.

The package may include ATS formulated clutch material bonded in-house to CNC laser-cut clutch steels, depending on the application. This supports better clutch holding capacity in demanding diesel use.

Stage 6 packages may also include a TripleLok or triple-patented Five Star torque converter, depending on application. This package is confirmed to include a torque converter with a 1,300–1,500 rpm advertised flash stall rating.

Other possible Stage 6 features include Torrington bearing construction, performance transmission pump, modified high-performance clutch packs/bands, modified valve body focused on precise shifts and increased line pressure/torque capacity, and new bearings, seals, and gaskets, depending on the application.

The included transmission controller supports electronic control, and Stage 6 package features may include a Co-Pilot transmission controller depending on the exact application.
