Hi,
I'm not sure what is meant by 3x transmission flush. Interestingly, the manual simply suggests draining and refilling the fluid when it's dirty. Take a look through this. There is an ATF strainer bolted to the valve body, but that needs removed and inspected to even see if it is plugged. (See pic 3)

Fluid Capacity
1.4 L (1.5 US qt) at fluid change
1.6 L (1.7 US qt) at overhaul
Always use Honda Manual Transmission Fluid (MTF). Using engine oil can cause stiffer shifting because it does not contain the proper additives.
5. Install the filler plug (C) with a new sealing washer (D).
6. If the maintenance minder required to replace the fluid, reset the maintenance minder. If it did not, select BODY ELECTRICAL, GAUGES, ADJUSTMENT, MAINTENANCE MINDER, RESET, MAINTENANCE SUB ITEM 3 with the HDS.
