WORK SAFELY! It is recommended that the installation be performed prior to installing the
transmission in the vehicle. If you are installing in a transmission already in the vehicle, for maximum
safety, perform on a clean, level surface and with the engine turned off. Place blocks or wedges in
front of and behind both rear wheels to prevent movement in either direction.
CLEANLINESS! It is critical to perform this work in clean environment to ensure that dirt, dust or
other contaminants don’t get introduced into the transmission case.
