Welcome
Thank you for purchasing the BD AutoLoc Kit. This manual is to aid you with your
installation and operation of the unit. We strongly suggest that you retain this
manual for any future reference.
NOTE: This kit cannot be installed on the Jacobs E-Brake system for the
Dodge ISB 24 valve application. Also, for all US Gear D-Celerator exhaust
brakes, you must use the 1030395 TorqLoc kit.
The BD AUTOLOC Advantage
Currently, exhaust brake usage can cause high temperatures in the automatic
transmission due to torque convertor slippage. Only 10% to 80% of the retarding
force is transferred through the fluid coupling of most torque convertors.
The BD AutoLoc commands the lock-up clutch of the torque convertor to stay
engaged when the BD Exhaust Brake is activated. This allows up to 100% of the
retarding force to be transferred while in 3rd and 4th gear. Also, transmission oil
temperatures will remain low because of little or no slippage occurring in the
convertor in these gears.
Operating the BD AUTOLOC
The AutoLoc works off of the power signal from throttle or toggle switch of the
exhaust brake that activates the valve to close, and, will only take effect when the
vehicle is above a set speed (approximately 25 to 30 mph), the exhaust brake is
activated and the torque convertor lock-up clutch is engaged.
For all applications with the exception of the BD Exhaust Brake on the Ford
PowerStroke, this kit does not control the exhaust brake, it only utilizes the exhaust
brake power signals to activate the control of the lock-up clutch. With the BD
Exhaust Brake on the Ford PowerStroke, the unit controls the activation of the
brake, which will shut the brake off once the vehicle speed drops below the set
speed.
The lock-up clutch usually engages when the vehicle is cruising, with little throttle
action. On most vehicles, the lock-up clutch will be engaged when applying
pressure to the accelerator pedal until lock-up engages, then lift foot off of the
accelerator.
Accelerator pedal pressure is also required after shifting out of or into overdrive to
reengage the lock-up. The AutoLoc is programmed to disengage the lock-up clutch
once the vehicle drops below the set speed.

For proper operation of the Dodge transmission, the lock-up clutch must be
disengaged before the transmission will shift out of overdrive and into 3rd gear. The
AutoLoc module compensates for this by disengaging the lock-up clutch when the
"O/D" button is activated to turn the overdrive off while the exhaust brake is turned
on. To reactivate the lock-up, apply pressure to the accelerator pedal until lock-up
engages, then lift foot off of the accelerator pedal.
On all vehicles, the transmission should be shifted out of overdrive if speed drops
below 40mph. Otherwise there could be a transmission shudder as the vehicle’s
speed continues to drop until it reaches the set speed that the AutoLoc unit will
disengage the lock-up.
IMPORTANT: With Dodge trucks, the module has an Overdrive inverter option that
will disengage the Overdrive when the truck starts to move after being started up.
This will prevent possible transmission shutter on trucks with raised horsepower,
and, will allow for the transmission to lock-up the clutch in third gear before reaching
overdrive when starting to up-shift from a dead stop, allowing cooler fluid
temperatures when driving at “city” speeds. This is an option and does not need to
be connected for proper operation of the AutoLoc module; ignore all references to
the “Inverter” if this option is not desired.
Transmission Quirks
Some Dodge trucks built between the production dates of 09/1995 to 04/1996 have
had computers that the programming for the transmission control has caused some
lock-up control problems and/or will cause the AutoLoc not to operate correctly. If
this occurs, the computer can be "re-flashed" to current specifications at most
Dodge dealerships. Sometimes this can be done under warranty, but labor charges
may apply (usually 1/2 hour).
Some Dodges that are of the 1999-2002 model years and of California
specifications may require the transmission relay to be re-installed back into its
socket, which would have been removed in the "1996-2002 Dodge "TRANS" Relay
Bypass" section of this manual.
Other items installed that may affect the operation of the transmission may have an
effect on the operation of the AutoLoc (i.e. auxiliary transmissions). Please make
this known if contacting the BD Technical Service Department.

Compatibility With Other Exhaust Brake Brands
Most of the provided diagrams, instructions and parts relate to the installation and
operation of this unit in conjunction with a BD Exhaust Brake. In this manual, we
have provided some diagrams and additional instructions for some of the other
systems that we have had access to their diagrams.
An installation in conjunction with any other system should only be done with
instruction from one of our BD Technicians, with wiring diagrams and/or schematics
provided to them. Additional lead-time, parts and/or labor may be required. Though
we try to give all the information and instruction we can, to install the AutoLoc on
non-BD systems, we may have not thoroughly investigated these systems at our
factory, which may also lead to additional labor and/or parts, or even removal of the
AutoLoc.
NOTE - Pac Brake exhaust brakes only: If the truck has a 6BTA 12 valve
engine with 60lb springs, remove the Pac Brake valve and drill out the
pressure relief hole from 9/23” to 31/64”. This modification is not required in
24 Valve or newer trucks.
Adjusting For Your Application
Before starting the installation, open the control box up by removing two screws on
bottom of module. On the opposite end of the circuit board from the terminals, there
is a selection of 8 "dip" switches. The dip switches control the speed that the
AutoLoc module will disconnect the lock-up clutch. We have provided settings for
the module to disconnect the lock-up at approximately 25mph to 30mph. If you find
that the set speed is too high or low for the vehicle, phone our technical service
department for alternative settings.

NOTE: To insure proper function of the dip switches, flip each dip switch back and
forth once before setting them, even if the dip switches are already set for the
application it’s being installed on.
The “LED” (Light Emitting Diode) on the circuit board will show a Red light when the
AutoLoc is functioning. Once the unit is installed, test drive the vehicle to make
sure the light comes on and then turns off at the set speed.
Wiring And Plumbing
Disconnect the ground (Negative) terminals on all vehicle batteries before starting
installation. The following instructions are divided per wire going up to each
individual terminal labeled on the AutoLoc module, and the terminals in these
instructions will be numbered starting from the top at the +12V terminal. Follow
along with the diagrams following the written instructions for ease of installation.
After wiring, additional instructions will follow for 1996-up Dodges. For 1999-03
Ford PowerStrokes, remove the driver’s side front fender well for access to
computer harness. When possible, check for continuity through all Posi-Tap™
connectors after you have installed them. We suggest soldering and shrink tubing
all connections, but we also provide Posi-Taps™ for your convenience.

Testing The AUTOLOC
NOTE: When wiring the AutoLoc module, leave enough slack on the wires so that
the module can be pulled out enough to be easily visible during road tests, before
finally securing the unit under the dash. Reconnect Ground terminals on batteries
after installation and take the vehicle for a drive.
With no traffic around, cruise at a constant speed (higher than the set speed on the
module) with the transmission “locked up”, then let off the throttle.
The brake should have activated and you should feel the hold back. Again, with the
lock-up clutch engaged and while cruising, release the throttle pedal and check to
see if the LED on the module is lit. If the LED fails to illuminate, check the dip
switch settings, the VSS wire color and the connection to that wire. Check that the
wire is on the right terminal at the module, and make sure there is a good power
source and ground for the module.
Again, while cruising at a constant speed, let off the throttle and let the vehicle slow
below the set speed, the lock-up should disengage (and BD Exhaust Brake on Ford
PowerStroke application) below the set speed. If these situations fail to occur, then
check the wiring to the brake and module, and, check terminal locations on the
module.
On Dodges, after starting, the O/D off light should have illuminated (if that option
was hooked up). Turn O/D on (light off) and the brake on, drive until overdrive is
reached and lock-up has occurred then let off the throttle. With the brake and lockBD Engine Brake Inc.

up clutch engaged, push the overdrive button to check that the lock-up clutch
disengages and the transmission shifts out of overdrive. If this fails to occur, check
the O/D wire color and connection to that wire, and, the wiring on the terminals of
the module.
If any of the functions still fail to occur, phone our technical service department for
further assistance. If it is required to bypass the effects of the module, unplug the
Blue and Yellow wires at the transmission wire and plug the transmission wires
together. After final wiring and testing has been done on the vehicle, mark the label
on the module for the application (vehicle and kit part number). Secure module to a
harness or bracket under dash with tie wraps.
Dodge “TRANS” Relay Bypass (1996-2000)
Remove the cover on the Power Distribution Center (PDC) box, behind the driver's
side battery. Replace the "TRANS" relay (see diagrams below, or bottom of PDC
cover) with Copper Jumper.
This is not required on 1999-up California model trucks.
If the Engine Service Light comes on after operation, try reinstalling the relay, then
clear the fault code from the ECM.
2001-up: These vehicles USUALLY do not require the relay to be removed and
having the jumper wire installed. Please test the installation with the factory relay
installed. If any symptoms occur, remove the relay and install the jumper wire.

AUTOLOC vs. TORQLOC
The difference between the AutoLoc and TorqLoc is that the AutoLoc automatically
controls the TCC lock up signal once it receives a power signal from the exhaust
brake switch and the TorqLoc has a manual position, automatic (or AutoLoc
position), and an Off position.
So, in comparing between the AutoLoc and the TorqLoc, the TorqLoc will force the
convertor clutch to lock up & the AutoLoc will only hold an already locked up
convertor clutch. When you ask for an overdrive to third gear shift, the TorqLoc
doesn’t wait for the computer to lock up the clutch, it sends its own signal to the
convertor clutch, and as long as you are A) above the set speed and B) the
transmission is hydraulically correct, [throttle pressure is applied], the TorqLoc will
force a lock up.
The AutoLoc cannot force a lock up, but can only hold it on deceleration. The
Chrysler transmission does not lock up in third gear, unless the overdrive is turned
off. Also, the Chrysler transmission won’t allow an overdrive to third gear downshift
if the TC clutch is locked up. This holds true not matter what system you are using
to hold the TC locked up.
While driving with the overdrive turned off, and the AutoLoc is turned on, the
transmission shifts from first to second to third, and then locks up.
Anytime after the lock up has occurred and you take your foot off the accelerator,
the AutoLoc will turn the exhaust brake on and hold the torque convertor clutch
locked until about 25mph when it will then turn off the torque convertor clutch.
When driving on the freeway in overdrive, the torque convertor clutch will be locked
up and the AutoLoc turned on, if you release the throttle the AutoLoc will apply the
brake and hold the TC clutch lock up.
To increase the amount of retarding horsepower, turn off the overdrive and the
AutoLoc will sense this signal and cut the signal that’s holding the torque convertor
clutch applied, the transmission will then downshift into third gear. At this point you
should apply throttle pressure until the factory computer says everything is okay and
locks up the torque convertor clutch.
As soon as this happens you should remove throttle pressure and the AutoLoc will
turn the exhaust brake on and keep the torque convertor clutch applied until you get
down to about the 25mph mark. The set speed is adjustable, one can set it for a
higher mph, so you don’t have to worry about remembering to turn off the overdrive
or lower if one has 4:10 gears.
Now suppose you’re driving along, overdrive is on, the AutoLoc is on and you need
to make a stop or slow down, but don’t need the extra retarding horsepower of third
gear or you don’t have time to wait for the downshift, applying throttle and waiting for
lockup, (this would all take about 4-6 seconds) and you don’t want the shuddering

that would occur when you have a locked up torque convertor clutch & you’re going
to be doing less than 35 mph in overdrive.
You can do any of the four following actions to cancel out the system: 1) turn off the
AutoLoc switch, 2) turn off the overdrive, 3) lightly step on the throttle pedal, or 4)
pull the gearshift lever down into second gear. Turning off the overdrive or the
AutoLoc are the best of the four options.
Now enters the TorqLoc, it should only be used under light throttle applications. No
matter whose torque convertor you are using, the converter clutch has only so much
holding power & if you exceed this you will start to slip the clutch, thereby starting
the demise of your convertor clutch.
An example of when to use the TorqLoc position would be when you are on a
winding road where you are on and off the throttle a great deal and you don’t want
to keep locking and unlocking the convertor clutch. The TorqLoc will hold the
convertor clutch locked up, preventing that from happening.
You must keep in mind, while doing this, that if you apply too much throttle pressure,
especially at the lower rpm band, you may start to slip the convertor clutch. A
general rule of thumb when holding the convertor clutch locked up is no more that 1
lb of boost for every 100 rpm of engine speed.
