BD Diesel AutoLoc Ford Dodge Chev 6.5LT

If your torque converter is not locked up when the exhaust brake is applied, you are only benefiting from a fraction of its retarding power. The BD AutoLoc commands the torque converter to lock up, and stay locked up, any time the exhaust brake is applied in third and fourth gears. This not only helps with engine braking, but because there is no clutch slippage, transmission oil temperatures remain low. The lock-up clutch and exhaust brake automatically disengage at low speeds to prevent stalling and transmission/converter damage.
