INSTRUCTIONS
Wear safety goggles to protect your eyes.
Wear Nitrile®, Neoprene® or PVC gloves to protect your hands.
Wear a long-sleeved shirt to protect your arms.
IMPORTANT! The following instructions must be read and understood before attempting to use the BG PXT®2 Performance Exchange® for Transmissions. Read product Safety Data Sheet before handling any BG product.
  1. Make sure this service is performed in a well-ventilated area.
  2. Keep all hoses and tools away from moving engine parts.
  3. Check all lines, hoses and points of connection for cracks and leaks before and after service.
  4. WARNING! Transmission fluid could be under pressure. Use EXTREME CAUTION when removing transmission lines and adaptors before and after the service. Transmission fluid and connections will likely be very hot.
  5. The BG PXT®2 is designed for use with BG products described in these instructions only. The use of any other chemicals or fluids with this system will void all warranties and could create hazardous conditions.
  6. Do not spray solvents on flow indicator; clean using mild detergents only.
  7. Dispose of used transmission fluid in accordance with federal, state, and local regulations.

General Information

The BG PXT®2 can perform transmission fluid exchanges with an easy-to-use onboard digital interface.
BG Transmission Service
  1. The BG PXT®2 services automatic transmissions (AT), continuously variable transmissions (CVT), dual clutch transmissions (DCT) and direct shift gearboxes (DSG).
  2. The BG PXT®2 begins with a thorough cleaning of all internal transmission components using BG Quick Clean for Transmissions, PN 106. On automatic transmissions, this includes the valve body, the torque converter, the oil galleys and clutch pack, and the filter screen. All externally connected components, including transmission lines and coolers, are cleaned as well.
  3. Next, the BG PXT®2 removes the old fluid and cleaner while simultaneously installing new transmission fluid. The BG PXT®2 operates cleaner, faster and is more economical than conventional drain-and-fill methods.
  4. The final step is the installation of BG ATC Plus® Automatic Transmission Conditioner, PN 310, or BG CVT Plus CVT and DCT Fluid Conditioner, PN 303, to restore pliability to seals and prolong new fluid life.

Preparing for Transmission Service

IMPORTANT! Perform a thorough inspection of the transmission, including related components such as lines and coolers. Make all repairs before performing this service. Check the vent on top of the transmission to be sure it is open and functioning. Inspect seal areas and gaskets; replace any that are leaking or badly deteriorated. If the pan gasket needs replaced, replace the transmission filter as well. Change the filter any time a repair service requires that the pan be removed.
  1. Start engine and run until normal operating temperature is reached.
  2. Check automatic transmission fluid level. If it is more than 1 quart/Liter low, add fluid, but leave room for 11 oz. (325 mL) of BG Quick Clean for Transmissions, PN 106. Do not overfill automatic transmissions.
  3. Add BG Quick Clean for Transmissions through the transmission dipstick tube. (For vehicles without a dipstick, add BG Quick Clean for Transmissions through the BG PXT®2 after connecting the vehicle).
  4. Drive vehicle for approximately 15 minutes. If it cannot be driven or if the BG PXT®2 has already been connected, place the vehicle on a lift so the wheels are above the floor. With the engine running, shift the transmission through all the gears to activate the valve body in the transmission. This ensures BG Quick Clean for Transmissions gets to all parts. During this procedure, make sure the brake is fully applied and the drive wheels have stopped turning between gear changes to prevent damage to transmission or differential assemblies. After adding BG Quick Clean for Transmissions, do not run the vehicle more than 30 minutes before performing the fluid exchange.
    Note: If the vehicle cannot be driven or placed on a lift, chock the wheels, apply brakes (including the parking brake) and carefully shift transmission through the gears several times with engine running at idle speed. Vehicle is now ready for the fluid exchange.
  5. Shut off engine and locate a junction in either of the transmission lines to allow installation of the appropriate adaptors (see “Possible Points to Make Connections” in these instructions). Separate the line at the chosen junction and attach adaptors. Use pinch-off clamps on rubber lines to prevent fluid loss during connection.
    Note: Some vehicles also use the radiator to cool the engine oil. Be sure the lines you are working with go to the transmission and not the engine.
  6. Connect the BG PXT®2 H1 and H2 service hoses to the adaptors. Either hose can be attached to either adaptor. Flow direction corrects automatically after the engine is started.
  7. Power up the BG PXT®2 by attaching its power cables to the vehicle’s battery or other 12 volt DC power source.
  8. Start engine and check for leaks.
  9. Follow the on-screen instructions to proceed with BG Transmission Service.

Preparing the BG PXT®2 for Next Transmission Service

The BG PXT®2 needs enough transmission fluid in the T1 new fluid container and enough space in the T2 used fluid container to handle the volume requirements of the next vehicle. The T1 and T2 containers do not have to be completely full or empty, respectively, before the next service. The BG PXT®2 allows multiple services on one charge (and one emptying) of the machine.
  • To fill the BG PXT®2, pour transmission fluid into the F1 funnel.
  • To empty the T2 used fluid container, connect the power cables to a 12 volt DC power supply.
  • Press the T2 button on the touch screen. Follow the on-screen instructions. The BG PXT®2 stops automatically when the container is empty.

Possible Points to Make Connections

(Note: It is only necessary to disconnect one line.)
CAUTION: Be sure the line is a transmission fluid line and not an engine oil line!

  4. External transmission fluid cooler
  5. Transmission front wheel drive
  6. Transmission rear wheel drive
  7. Opposite side

Connection may be made at any accessible point along the transmission fluid route. However, it is possible that the adaptors may not fit every connection encountered.

Inspection and Maintenance

Before each use, inspect the general condition of the BG PXT®2. Check for loose screws, as well as misaligned or binding parts, cracked or broken parts, and any other condition that may affect safe operation of the machine. Correct any of these conditions before further use. Do not use damaged equipment. The BG PXT®2 requires no scheduled maintenance. However, there are four strainers (three in the manifold block and one on the used fluid pump) that can be removed and cleaned if the BG PXT®2 starts to function irregularly.
  • Use only mild detergents and a soft cloth to clean the flow indicator and user interface touchscreen. Do not use harsh chemicals or abrasives. Do not spray brake cleaner on these components.
  • Keep all receptacles used for the transfer of new fluids and chemicals clean. Remove and wash the T1 new fluid container if there is any particulate matter on the bottom. Keep the F1 and F2 funnels covered when not in use.
  • The container platforms are supported by load cells that have a maximum capacity of 70 lbs/32 kg. Do not step on or drop a loaded container onto these platforms. This will severely damage the BG PXT®2.

Calibration

The BG PXT®2 is calibrated at the factory and should not need further adjustment. However, if the BG PXT®2 loses calibration, do the following:
  1. From the home screen, press the gear icon.
  2. Press the scale icon.
  3. Press the T1 and T2 buttons on the bottom until they both turn green.
  4. Press the home icon.
  5. Follow the Empty T1 procedure. Let the motor run until it turns off on its own.
  6. Follow the Empty T2 procedure. Let the motor run until it turns off on its own.
  7. Go back to the scales screen (steps 1 and 2). The T1 and T2 buttons should both be gray. If one or both are still green, run the empty procedure for T1 and/or T2, and let it run until it stops on its own.
  8. The values should be between –0.5 and –0.7 on both T1 and T2.
