Description
Product Overview
The Bowler Performance Tru-Street Series Automatic Transmissions 1047000 is a professionally remanufactured automatic transmission designed for compatible LS-based small block engine applications. It is built for buyers who want a reliable street-focused automatic transmission package with the right balance of drivability, performance, and fitment-focused specifications.
This unit is identified by Manufacturer’s Part Number 1047000 and Summit Racing Part Number BTM-1047000. These identifiers help vehicle owners, mechanics, LS swap builders, restoration shops, performance shops, service departments, and drivetrain specialists confirm the correct transmission before purchase.
The package includes a 4L70E transmission and a 2,400–2,800 rpm stall torque converter for LS-based small block engines. This is an important application detail because converter behavior, electronic transmission control, engine compatibility, and driveline setup must all match the vehicle build.
The transmission features a 4-speed configuration, Chevy bellhousing bolt pattern, forward shift pattern, and automatic valve body. It is also lockup compatible, supporting proper converter lockup function when matched with the correct control system and vehicle setup.
Key drivetrain details include a 30-spline input, steel input shaft, 3.06 first gear ratio, 9.000-inch tailshaft length, slip-on yoke style, and steel/aluminum clutch hub. The transmission uses an OEM-style aluminum case with a gray finish and a stock steel pan with a gray finish.
The flexplate is not included, the transmission controller is not included, the wiring harness 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 required supporting components before ordering.
Fitment and Application Details
The Bowler Performance 1047000 Tru-Street automatic transmission should be matched carefully to the intended LS-based Chevy application before purchase. Automatic transmission fitment can vary by engine, vehicle platform, bellhousing pattern, converter setup, flexplate, electronic controller, wiring harness, throttle position signal, speed signal, transmission mount, crossmember position, driveshaft length, yoke setup, cooler routing, and installation hardware.
Important fitment details to confirm include vehicle year, make, model, engine, drivetrain, LS-based small block compatibility, Chevy bellhousing bolt pattern, 4L70E compatibility, torque converter compatibility, flexplate requirements, converter bolt pattern, crankshaft pilot fitment, transmission mount location, crossmember position, 9.000-inch tailshaft length, slip-on yoke style, driveshaft length, 30-spline input compatibility, shifter linkage, electronic controller requirements, wiring harness requirements, lockup-control requirements, cooler line routing, fluid specifications, and installation hardware.
This package includes the 2,400–2,800 rpm stall torque converter, but the flexplate is not included. Buyers should confirm the correct flexplate for the LS-based small block engine, crankshaft, converter bolt pattern, and intended application.
The transmission controller is not included, and the wiring harness is not included. Because the 4L70E is an electronically controlled automatic transmission, buyers should confirm the correct controller, harness, speed signal, throttle position input, and lockup-control requirements before installation.
The transmission cooler is not included, so buyers should plan the correct cooler setup separately, especially for performance street use, LS swaps, heavier vehicles, or warm operating environments.
For a complete installation, additional components may be required, including a flexplate, controller, wiring harness, cooler, cooler lines, dipstick, transmission fluid, transmission mount, crossmember hardware, driveshaft/yoke components, shifter linkage, seals, and vehicle-specific installation parts.
Build Quality and Reliability
The Bowler Performance Tru-Street Series Automatic Transmissions 1047000 is part of the Tru-Street Series, a line built for buyers who want a professionally prepared street transmission rather than a basic replacement unit.
Bowler Performance Transmissions has been building transmissions since 1963, and the Tru-Street approach focuses on detail, careful remanufacturing, dyno testing, and safe shipping preparation. Each Tru-Street automatic transmission is fully remanufactured, handled by one qualified technician, dyno tested, and custom packaged for shipment.
This attention to build process makes the 1047000 appealing for LS-based small block builds where the transmission needs to perform well on the street while matching the right electronic controls and supporting components.
The included 2,400–2,800 rpm stall torque converter adds value for compatible street performance applications, helping buyers start with a matched transmission-and-converter foundation.
The stock steel transmission pan, OEM-style aluminum case, steel input shaft, 30-spline input, and 3.06 first gear ratio provide important specifications for proper drivetrain planning.
The built-in transmission shield and flexplate shield are notable safety-related features that add value for buyers who want a more complete performance-minded setup.
What Makes This Transmission a Strong Choice
The Bowler Performance 1047000 Tru-Street automatic transmission is a strong choice for buyers who need a remanufactured 4L70E transmission for compatible LS-based small block Chevy applications.
The included 2,400–2,800 rpm stall torque converter adds major value by pairing the transmission with a converter suited for compatible performance street use.
The 4-speed configuration and 3.06 first gear ratio are important for buyers planning acceleration, drivability, gear spread, rear axle ratio, and tire-size compatibility.
The lockup compatible design supports converter lockup function when installed with the correct control system and wiring setup.
The 30-spline steel input shaft, steel/aluminum clutch hub, and OEM-style aluminum case provide important drivetrain details for performance-minded buyers and professional installers.
The 9.000-inch tailshaft length and slip-on yoke style help buyers confirm driveline compatibility before installation.
The built-in transmission shield and flexplate shield are strong value points for buyers looking for a transmission package with additional protective features.
Ideal Buyers and Use Cases
The Bowler Performance Tru-Street Series Automatic Transmissions 1047000 is ideal for LS swap builders, Chevy performance vehicle owners, restoration builders, street machine owners, mechanics, repair shops, drivetrain specialists, hot rod builders, custom vehicle shops, and service departments that need a quality 4L70E automatic transmission for compatible LS-based small block applications.
It is suitable for builds requiring a remanufactured 4-speed automatic transmission, Chevy bellhousing bolt pattern, 2,400–2,800 rpm stall torque converter, lockup compatibility, 30-spline steel input shaft, 3.06 first gear ratio, 9-inch tailshaft, and slip-on yoke style.
This product is useful for LS-based small block street cars, hot rods, restomod builds, performance cruisers, street machines, and compatible Chevy drivetrain projects needing a professionally remanufactured automatic transmission package.
It is also a practical choice for professional installers confirming required supporting components such as the flexplate, electronic controller, wiring harness, cooler, cooler lines, fluid, dipstick, transmission mount, driveshaft connection, shifter linkage, and installation hardware.
The best buyer for this transmission is someone who can confirm the LS-based small block application, electronic-control requirements, converter fitment, and driveline setup before ordering.
