What would happen if you drained the pan via the plug,(2005 Honda Accord 6), replaced plug and started the engine but did not move? Would there be flow from the TC to the pan of more old fluid to be drained and replaced? What trouble could this cause?
Transmission fluid draining question.

I'm guessing here but, if the car will not move then the oil pump can't pressurize the system, then nothing happens. I think you may be trying to do a flush? Another way I've done is to do a pan drain and refill. Drive 50 miles and do another pan drain and refill. If you do this 3X times you will have ~ 90% new fluid. Just a thought. Ed
On Fords you disconnect a cooler hose and start the engine. This will pump out about a gallon. Then stop engine (at this time I drain the pan and change filter) then pour in 10 quarts and repeat. Stop engine when flow lessens, connect hoses and add about 4 quarts.
If you drain the pan, the oil pump won't be able to pick up any more fluid and you'd probably not get any additional flow to be drained. Besides, the lack of fluid flow through the trans would probably cause damage somewhere even though you're not moving. Remember the torque converter and oil pump are still turning any time the engine's running. If you're going to do a home-brew trans flush, the best bet is to drain the pan, refill, disconnect a cooler hose, flush a few quarts, stop engine, refill, flush a few quarts, etc. until you've ran out the total fluid capacity of the trans.
Do an extra drain & fill.
Save yourself a lot of grief.

Just to clarify, my post was actually regarding the original question, despite what the header above my post may indicate.
I wasn't questioning your method, shoz.
