Description
B&M Racing Street/Strip T400 Automatic transmission for Buick, Oldsmobile and Pontiac applications with large diameter bushing for use with large 1.875 inch Spicer yoke (part number 2-3-10431X.) This transmission is a complete ready to run unit (less converter) for high performance street and mild strip use. Since Chevrolet based T400 cores are getting harder to find, we’ve included a B&M Racing B.O.P./Chevy adapter plate so you can also use this transmission on 62 and later small block and big block Chevy engines. This transmission provides firm shifts and features a standard forward shift pattern. Includes a 2.48:1 first gear ratio, 1.48:1 second gear, rebuilt front pump utilizes B&M pressure regulator spring and shims, all new B&M high performance friction plates, new intermediate roller clutch, new kickdown band with welded anchors, machined center support with new case saver ring, all new thrust bearings and races, new adjustable modulator and silencer ring, new external electric connector, kickdown solenoid and a recalibrated valve body. Transmission has a 4″ tailshaft. Recommended max 600 HP and 550 Lb Ft
