INTRODUCTION
to the TSD440
Congratulations on the purchase of your Flo-Dynamics TSD440 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 TSD440, you can exchange the
transmission fluid through the vehicle's dipstick tube. 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 TSD440 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 TSD440 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 TSD440 exchanges fluid through the vehicle’s dipstick tube.
• The ATF fluid exchange, from setup to finish, typically takes 10 minutes or less!
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 TSD440 before
performing your first ATF exchange.

Ingestion: If large amount, get medical attention.
If any irritation persists, get medical attention.
• Dispose of used fluid according to environmental laws and regulations.
Although automatic transmission and power steering fluid pose no significant health hazards,
some individuals may experience adverse reactions upon contact. Pressurized fluid can cause
serious injury.
Risk of unexpected vehicle movement.
• Block drive wheels before starting vehicle’s engine to begin an exchange.
• Unless instructed otherwise, set parking brake and put gear selector in park.

and quick-disconnect fittings; internal: hoses and all fittings) may reach temperatures
uncomfortable to the touch. Exercise caution in avoiding contact with these items.
Hot components can cause injury or discomfort.
Ratchet mechanisms and tools may slip or break if dirty. Mismatched or partially worn parts can
cause ratchet or any tool to slip or break.
• Frequently inspect and clean any tools used, and lubricate all non-sealed ratchet
mechanisms with light oil.
• Do not replace worn parts individually. If adapter hose fittings become worn, see
“Appendix C – Replacement Parts” to order new hoses.
• The use of any other accessories not specified in this manual may create a hazard.

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.
4.02MAINTENANCE 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.
