BD Diesel AutoLoc Ford 7.3L 94-97 OBS - 1030390
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.

Installed the BD AutoLoc on my 02 F450 PSD,attempting to make the Pac brake (came with the truck when I purchased it) work like the BD turbo mounted with AutoLoc that was on my 01 F250 PSD. The autoloc works great, the Pac brake is going in the trash can, it's not half as awesome as the BD exhaust brake. Riffraff diesel rocks !
