The BD-Power 1031300 AutoLoc Lockup Controller for your 2003-2007 Ford 6.0L Powerstroke is designed to increase fluid pressures to help prevent slippage and maintain positive clutch contact. If your torque converter isn't locked up on deceleration or when the exhaust brake is applied (if equipped), you're only benefiting from a fraction of its retarding power. The BD Auto/PressureLoc 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's 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.

• Works Great With Exhaust Brake
• Help Keep Transmission Fluid Temperatures Low
• Prevents Slippage, Maintains Positive Clutch Contact
