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.

Product Overview

Currently, exhaust brake usage can cause high temperatures in the automatic transmission due to torque converter slippage. Only 10% to 80% of the retarding force is transferred through the fluid coupling of most torque converters. The BD AutoLoc commands the lock-up clutch of the torque converter to stay engaged when the BD Exhaust Brake is activated. This allows up to 100% of the retarding force to be transferred while in 3rd and 4th gear. Also, transmission oil temperatures will remain low because of little or no slippage occurring in the converter in these gears.
