Product Overview
The Chevrolet Performance Automatic Transmissions 19432680 is a factory-engineered 6-speed automatic transmission kit built for compatible Chevrolet Performance crate motor applications. Designed for use with LT1, LT4, and LT8 crate motors, this transmission package gives builders a clean, new Chevrolet Performance drivetrain solution for compatible 4WD projects requiring the 6L80-E platform.
This transmission kit is identified by Manufacturer’s Part Number 19432680 and Summit Racing Part Number NAL-19432680. These product identifiers help vehicle owners, restoration builders, mechanics, performance shops, service departments, custom vehicle builders, and drivetrain specialists verify the correct transmission package before purchase.
The transmission features a 6-speed configuration, Chevy bellhousing bolt pattern, forward shift pattern, and automatic valve body. It is designed to support automatic operation while offering the drivability benefits of a modern 6-speed automatic transmission setup.
Important performance and fitment details include a 4.02 first gear ratio, lockup compatibility, deep steel transmission pan, natural pan finish, aluminum transmission case, and an advertised 2,400–2,800 rpm flash stall rating.
This kit includes the torque converter, transmission controller, and wiring harness, which are major value points for builders planning a compatible electronic automatic transmission installation.
The flexplate is not included, the transmission cooler is not included, transmission fluid is not included, and the dipstick is not included, so these supporting components should be confirmed before installation.
Fitment and Application Details
The Chevrolet Performance 19432680 automatic transmission kit should be matched carefully to the intended Chevy application, crate motor, drivetrain, and installation setup before ordering. Automatic transmission compatibility can vary by engine, bellhousing pattern, transmission code, converter setup, flexplate, controller, wiring, cooler routing, transfer case requirements, mount location, crossmember position, driveshaft length, and fluid requirements.
This kit is designed for compatible Chevrolet Performance LT1, LT4, and LT8 crate motors. It is listed under Chevrolet applications with the 6L80-E transmission manufacturer code and 4WD drivetrain.
Important fitment details to confirm include vehicle platform, crate engine selection, LT1 compatibility, LT4 compatibility, LT8 compatibility, 6L80-E compatibility, Chevy bellhousing bolt pattern, torque converter fitment, flexplate requirements, converter bolt pattern, crankshaft pilot fitment, transmission mount location, crossmember position, transfer case compatibility, driveshaft/yoke requirements, shifter setup, controller compatibility, wiring harness routing, speed signal requirements, lockup-control setup, cooler line routing, fluid specifications, and installation hardware.
This package includes the transmission controller and wiring harness, but buyers should still confirm correct integration with the intended engine management system, vehicle wiring, throttle input, speed signal, and drivetrain setup.
The torque converter is included and has an advertised 2,400–2,800 rpm flash stall rating. This stall range should be confirmed against the engine, vehicle weight, axle ratio, tire size, and intended use.
The flexplate is not included, so the correct flexplate should be selected for the LT crate motor, crankshaft, converter bolt pattern, and application.
The transmission cooler is not included, so buyers should select an appropriate cooler setup for the vehicle’s intended use, especially for performance driving, towing, 4WD use, or warm operating conditions.
For a complete installation, additional components may be required, including a flexplate, transmission cooler, cooler lines, transmission fluid, dipstick, transmission mount, crossmember hardware, transfer case components, driveshaft/yoke components, shifter parts, seals, and vehicle-specific installation hardware.
