Optional Transmission Filter Change:Pan Drop Style Service Procedure.
If the vehicle’s transmission pan filter is to be replaced, perform the following steps.
a) Follow steps 1 thru 7 then press the DRAIN button on the unit’s control panel. Let the
engine run until the unit’s alarm sounds and the LOW VEHICLE FLUID and ENGINE STOP
and ENGINE START lights are flashing. This means that the transmission has emptied most
of the fluid from the transmission’s fluid pan. Stop engine. Press the STOP button once to
cancel alarm. NOTE: Do not disconnect the power cord from the battery or move the
Trans Tech once the service has begun.
b) Replace or clean the vehicle’s transmission fluid filter and reinstall the transmission’s oil pan
following outside manufacturer’s recommendations.
c) Press the CHANGE FLUID button. The unit will begin filling the vehicle’s transmission
corresponding to the amount of fluid previously emptied into the unit’s WASTE tank.
d) When the pan has been refilled the START light will flash and the alarm will sound until the
vehicles engine is started and pressure is registered on the gauge. The pump will be
stopped until the Start light changes to solid. After the START light changes to solid
the DRAIN and FILL lights will be on. The fluid exchange process is then restarted and the
exchange will continue until the level in the clean tank gets to zero.
Continue with the service until all fluid has been exchanged and the unit stops automatically.
The COMPLETE light will come on and unit will beep continuously until STOP is pushed.
e) Let engine run for one minute, then check the transmission’s fluid level.
If level is low:
a) When the complete light is on, and the low clean fluid light is on: Press and hold the FILL button
for 10-15 seconds.
b) Re-check fluid level, repeat step “a)” if necessary.
If level is high:
a) When the complete light is on, and the low clean fluid light is on: press and hold the DRAIN button
for 10-15 seconds.
b) Re-check fluid level, repeat step “a)” if necessary.
13. Stop engine and let cool if necessary.
14. Disconnect hoses from TRANSTECH and connect the vehicle’s cooler lines to their original connection
ports.
15. Start the engine, check cooler lines for leaks, and re-tighten as necessary.
16. Step on the foot brake firmly, then slowly shift the gear lever to Low Gear (first gear) then back to Park.
Do final check of transmission’s fluid level.
17. Empty waste fluid tank.
18. Leave unit standing empty (to the zero mark) unit next service.
NOTE: use of the “H” flow control adapter is optional.
If you choose to hook the TransTech-III directly to the cooler lines and you do not have the clean and dirty
hoses connected properly for the flow direction, then the pressure gauge will drop to zero and the unit will
not let you start the service.

Letting the transmission run for an extended period of time without fluid can cause serious
damage to internal components.
