BD-Power (1031300) AutoLoc Lockup Controller
BD Power Auto\PressueLoc - 2003-2007 Ford 6.0L PowerStroke - 1031300
Maximizes Your Exhaust Brake’s Retarding Power—Automatically!
If your torque converter isn’t locked up when the exhaust brake is
applied, 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.
The Auto/PressureLoc also increases the fluid pressures to help prevent slippage and maintain positive clutch contact.
