B&M Converter Lockup Controls

4.6 out of 5 stars 47 Customer Reviews

B&M converter lockup controls provide dash-mounted control to govern converter lockup at any speed between 30 and 90 mph. An LED display tells whether the converter is locked or unlocked. These kits eliminate converter lock and unlock cycling and premature unwanted converter lockup, avoiding engine lugging and spark knock. They also provide lockup at highway speeds for fuel economy. These kits are perfect for converter lockup operation when converting a non-lockup equipped vehicle to a lockup-style transmission and converter.
