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.

The
BD AutoLoc is a computer that commands the torque convertor lock-up
clutch to stay applied when an exhaust brake is engaged. The AutoLoc
ensures that 100% of the retarding force is being transferred in 3rd
and 4th gears, thus, transmission oil temperatures remain low because
convertor slippage no longer occurs in these gears. The lock-up clutch
and brake automatically disengage at low speeds to prevent stalling
and transmission and convertor damage. The convertor lock up clutch
applies with accelerator pedal pressure, and the AutoLoc captures
this signal. After shifting out or into overdrive in Dodge trucks,
apply heavy accelerator pedal pressure or quickly release the pedal
and the lock up clutch will engage. Exhaust brakes cause high automatic
fluid temperatures due to the torque converter slippage and without
a AutoLoc only 10-80% of the retarding force is transferred through
the (unlocked) fluid coupling of a torque convertor. You can drive
the truck with the AutoLoc engaged all the time. If you experience
a shutter when you slow down in over drive with the AutoLoc engaged,
you need to have the AutoLoc reset to disengage at a higher vehicle
speed. However, variances occur due to rear ratios and tire sizes.
