BD Diesel 1030390 - AutoLoc; Computer Commands Torque Converter Lock-Up Clutch To Stay Applied When Exhaust Brake Is Engaged;

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.

Features

• Maintains Lock-Up When Exhaust Brake Is Activated
• Ensuring 100% Of The Retarding Force Is Transferred
• Prevents Slippage and Subsequent High Oil Temps
• 12 Month/24000 Mile Warranty
