INTRODUCTION
to the TSD450
Congratulations on the purchase of your Flo-Dynamics TSD450 automatic transmission fluid
exchanging machine!
Simply put, this machine is the cleanest, safest, easiest, fastest, most thorough, and most cost-
efficient method of fluid exchange ever devised. Suddenly, regular automatic transmission
maintenance becomes a more realistic proposition. With the TSD450, you can exchange the
transmission fluid either through the transmission cooler lines OR through the vehicle's dipstick.
Transmission fluid exchanging is cleaner and easier than ever!
Transmission Fluid Exchange:
To attain the highest level of protection for internal transmission components and increase the
transmission’s life span to the maximum, it is recommended that the transmission’s lubrication
system is serviced every 15,000 miles (or according to the vehicle owner’s manual). The Flo-
Dynamics TSD450 exchanges virtually all of the used transmission fluid to new, without even
requiring the transmission pan to be dropped. There is no spillage, and no mess.
• The TSD450 can be used practically anywhere – and with almost any vehicle.
• It is compact, mobile, and self-contained.
• It operates off the 12-volt battery of the vehicle being serviced.
• It does not require a pit, lift, or ramp.
• The TSD450 hooks up directly to one of the vehicle’s transmission cooler lines for a
transmission fluid exchange or through the dipstick.
• The ATF fluid exchange, from setup to finish, typically takes 15 minutes or less for inline
mode, and 10 minutes or less for dipstick mode!
No wonder an ATF exchange is the most requested method of preventative automatic
transmission maintenance today.
Please take time to read through this manual to familiarize yourself with the TSD450 before
performing your first ATF exchange.

ADDING CHEMICALS
When cleaning or conditioning the vehicles transmission it is recommended to add chemicals through the dipstick.
Always check the transmission fluid level prior to, and after, performing the service. The Instructions below assume a proper fluid
level before beginning.
ADDING CHEMICALS THROUGH THE DIPSTICK TUBE (PREFERRED METHOD)
Pour Transmission Cleaner or
Transmission Treatment directly into the
dipstick tube using a suitably sized funnel.
FOR SEALED TRANSMISSIONS & INLINE SERVICE
In the event that the
transmission does not have a
dipstick and is sealed, the
cleaner and conditioner
(optional) may be injected
directly into the vehicle via the
onboard chemical injection
system.
Select 5or 10 Minute Cleaning
from the Inline menu.
Select Yes from the Inject
Cleaner and Conditioner screen
Pour specified volume of
transmission cleaner into the
bottle on the front of the
machine after removing the cap
by holding the cap and carefully

remove draw tube from bottle
by raising cap upward. When
completed, reinstall the cap and
begin exchange.
If adding conditioner after
cleaning phase, press 1and
follow directions on screen.
If 1was pressed, the
conditioner will be added to the
vehicle near the end of the
exchange.
The fluid level in the vehicle will
be adjusted automatically

20 Printed in the U.S.A. for Flo-Dynamics ® Operations Manual
IV. TROUBLESHOOTING & MAINTENANCE
4.01 COMMON PROBLEMS / SOLUTIONS
Problem: “Power Failure” screen displays
Solution 1: Check battery connection. Make sure there are no loose connections, and the
machine’s battery clips are not reversed. Remove all corrosion from the battery
terminals. Make sure vehicle’s A/C system is turned off.
Solution 2: The vehicle’s battery is not putting out enough voltage to run the machine.
Connect the machine to a better 12V power source.
Stand-alone shelf batteries will not work.
4.02 MAINTENANCE PROCEDURES
• Replace Canister Filters (Part#: 940796A) when machine prompts you to do so:
Use a standard filter band clamp tool to unscrew old filters, and replace them with new filters.
Make sure new filters are on tight.
• Clean Waste Fluid Screen (Located in bottom of recessed hose tray area)
This helps eliminate surface tension caused by debris and contamination from the air.
Using a sharp pick, remove screen. Clean using degreaser and brush, and blow out with air
compressor.
• Periodically Wipe Down Exterior using a soft, damp cloth.
