Description
Product Overview
The B&M Street and Strip Transmissions 118002BM is built for buyers who need a remanufactured automatic transmission suitable for both street driving and performance use. As part of the B&M Street and Strip Transmissions line, this unit is designed for replacing a worn transmission, cruising, and racing in compatible Chevy applications.
This transmission is identified by Manufacturer’s Part Number 118002BM, Summit Racing Part Number BMM-118002, and UPC 019695001650. These identifiers help Chevy owners, street/strip builders, mechanics, restoration shops, custom vehicle shops, transmission installers, service departments, and drivetrain specialists confirm the correct B&M transmission before ordering.
The transmission features a 4-speed configuration, Chevy bellhousing bolt pattern, forward shift pattern, and automatic valve body. This makes it a strong fit for compatible builds where fully automatic operation is preferred.
The transmission is listed as lockup compatible, so buyers should confirm converter selection, lockup-control requirements, and vehicle electronics before installation.
This B&M transmission uses a stock natural steel pan, slip-on yoke style, hardened steel input shaft, 2.48 first gear ratio, OEM-style aluminum case, black case finish, and case-fill location. It is listed as remanufactured and sold individually.
The notes state that this transmission can be used with an HGM “Compushift” controller for transplant applications. This is an important detail for LS swaps, restomod projects, street/strip conversions, and custom drivetrain builds where electronic control may be required.
B&M remanufactured Street and Strip transmissions are put together with new gaskets, bushings, seals, thrust washers, high-performance friction materials, and gold zinc plated hardware. The front pump is rebuilt to B&M specs, and the valve body is recalibrated.
The torque converter is not included, 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 plan all required supporting components before installation.
Fitment and Application Details
The B&M 118002BM Street and Strip transmission should be matched carefully to the intended Chevy application before ordering. Automatic transmission fitment can vary by vehicle year, engine platform, bellhousing compatibility, torque converter setup, flexplate requirements, lockup-control needs, controller requirements, wiring, yoke style, transmission mount location, crossmember position, driveshaft length, shifter compatibility, cooler routing, fluid fill location, and installation hardware.
Important fitment details to verify include vehicle year, make, model, engine platform, Chevy bellhousing bolt pattern, original transmission family, drivetrain layout, torque converter compatibility, flexplate compatibility, converter bolt pattern, crankshaft pilot fitment, lockup-control setup, controller requirements, HGM Compushift controller compatibility for transplant applications, wiring needs, slip-on yoke compatibility, shifter compatibility, transmission mount location, crossmember position, driveshaft length, cooler line routing, transmission cooler requirements, fluid specifications, dipstick setup, and vehicle-specific installation hardware.
Because the torque converter is not included, buyers should choose the correct converter based on engine output, camshaft, vehicle weight, rear gear, tire size, stall needs, lockup-control requirements, and intended street or strip use.
Because the flexplate is not included, buyers should confirm the correct flexplate for the engine, crankshaft, converter bolt pattern, balance type, and starter setup.
Because the transmission controller and wiring harness are not included, buyers planning transplant or swap applications should confirm electronic-control needs before purchase. The product notes state that this transmission can be used with an HGM Compushift controller for transplant applications.
Because the transmission cooler is not included, a proper cooler setup should be planned before installation, especially for performance street driving, cruising, and racing.
For a complete installation, additional components may be required, including a torque converter, flexplate, controller, wiring harness, transmission cooler, cooler lines, transmission fluid, dipstick, shifter components, transmission mount, crossmember hardware, driveshaft/yoke components, seals, and vehicle-specific installation parts.
Build Quality and Reliability
The B&M Street and Strip Transmissions 118002BM is built for buyers who need a remanufactured automatic transmission with stronger street and strip durability than a basic worn replacement unit. B&M Street and Strip transmissions are designed for extreme conditions while remaining suitable for cruising and transmission replacement work.
These transmissions are assembled with new gaskets, bushings, seals, thrust washers, high-performance friction materials, and gold zinc plated hardware.
The front pump is rebuilt to B&M specs, helping support proper transmission operation and durability.
The valve body is recalibrated, giving the transmission a performance-focused internal setup for street and strip use.
The hardened steel input shaft is an important strength-focused feature for buyers confirming drivetrain durability.
The 2.48 first gear ratio, slip-on yoke style, lockup compatibility, and OEM black aluminum case provide important fitment and performance details for builders and installers.
Because this transmission is sold individually and does not include several supporting components, correct setup is essential. Buyers should confirm converter selection, flexplate compatibility, controller needs, lockup operation, cooling capacity, fluid fill setup, shifter compatibility, driveshaft/yoke fitment, and vehicle-specific hardware before installation.
