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 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'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.
