The legendary B&M transmissions for street use are a complete ready to run unit (less converter) for high performance street and mild strip use. The Street/Strip GM 4L60E is a must have for those wanting a high performance overdrive transmission. The years of experience and skills that B&M has gained at the track have been applied to these transmissions. Several parts have been replaced to assure optimal performance including replacing the factory friction plates with high performance friction plates, a re-calibrated valve body, Beast Sunshell, reinforced input drum, all new solenoids, wiring harness along with a rebuilt performance pump to assure optimum flow rate even in demanding conditions. A chrome transmission pan is installed to contain the fluid, but is aesthetically pleasing as well. The list goes on and on, which makes the Street/Strip GM 4L60E transmissions a very desirable unit. The transmission provides firm shifts and features a standard shift pattern, these are the finest available for street and strip use. Notes: We strongly recommend protecting your investment by adding a B&M Hi-Tek SuperCooler with all new transmission installations. Max 550 HP / 450 Ft/Lbs.
