The B and M AUTOMOTIVE Replacement Speedo Cable & Generator 70244 Kit is engineered for vehicles equipped with B&M GM converter lockup control systems. This kit addresses a critical need: when factory speedometer cables wear, fray, or snap, engine speed signal integrity suffers—causing erratic speedometer readings, failed lockup converter engagement, or transmission control faults. Mechanics and performance enthusiasts rely on this OEM-quality replacement to restore accurate vehicle speed feedback and proper torque converter operation without rewiring or ECU recalibration.
This replacement kit combines a new speedometer cable assembly with a matching generator (speed sensor output) to ensure smooth signal transmission between the transmission and instrument cluster. The cable is designed to meet factory tolerances and interface directly with B&M lockup control modules, eliminating signal noise that can trigger false converter lockup or unlocking cycles. Precise cable routing and gauge specification maintain the correct gear ratio feedback; any deviation causes speedometer inaccuracy or transmission logic errors. The compact 4.95 x 2.5 x 6.75-inch package weighs 0.82 lbs, making installation straightforward on most GM platforms without requiring extended downtime.
Technicians working with manual transmission swaps, engine conversions, or built performance platforms benefit most from this kit when retrofitting B&M transmission controllers. Original factory cables often fail under high-mileage use or when modified cooling systems alter cable routing geometry. Installation requires verifying correct speedometer gear matching to your rear axle ratio and confirming proper cable termination at both the transmission output shaft and gauge cluster connector. For anyone upgrading or maintaining a GM vehicle running B&M converter lockup management, this Replacement Speedo Cable & Generator 70244 Kit eliminates guesswork and delivers the signal fidelity modern transmission control demands.
