Transmission Service Procedure

Follow the steps below to connect the unit to the vehicle’s transmission cooler lines.
Make sure the vehicle has at least 1/8 tank of fuel before beginning this process.

Warning! It is not necessary to empty the waste tank before beginning an exchange. If beginning an
exchange with fluid in the waste tank ensure that there is less fluid in the clean tank than the remaining
capacity of the waste tank. Failure to do so will result in waste tank overflowing!

1. Add the correct amount of automatic transmission fluid into the TRANSTECH’S clean tank reservoir.

See chart:








NOTE: Quantity of fluid used per vehicle may vary depending on the condition of the fluid in the
transmission being serviced. Trucks and Step Vans may have a larger transmission, therefore may use
more fluid than specified in this chart.

2. Start engine, let run until it reaches operating temperature, turn engine OFF.

IMPORTANT

Do not perform the transmission service if the vehicle’s engine oil or coolant level is low. If

necessary, add motor oil and/or coolant.

Do not perform service if new transmission fluid is below 50 degrees Fahrenheit.

WARNING

Flammable Liquid can squirt out of pressurized lines when connecting or disconnecting.

Verify that engine and machine are both off before connecting or disconnecting cooler

lines or adapters.

Wear safety goggles.

Wear chemical resistant gloves when connecting or disconnecting fittings and adapters.

Wrap a shop towel around pressure fittings and adapters when disconnecting.

Avoid exposure to flames, sparks, hot engine parts, and other ignition sources.

Explosion or flame or exposure to flammable liquid and vapors can cause injury.
