1994 LS400 Transmission Flush questions
Hi.
There is probably an answer to my questions somewhere on this forum, but I have failed to find it using quite a bit of searching. Sorry ahead of time for the annoyance.
I want to use the flush method described on LexLS.com, which is partially credited to LOC user 92Lex (who is unfortunately inactive since 2008). You are supposed to disconnect the return line from the lower driver side of the radiator, connect a drain hose to the radiator fitting, and start the engine so that fluid can be pumped out from that fitting into a container (leaving the disconnected return line just dangling there, I suppose).
I have three questions:
1) Has anyone tried to do this alone?
2) How fast does it come out?
3) Does any fluid also flow out of the disconnected return line while the engine is running? I would guess not, but better to know ahead of time.
Thanks for reading

I have done it twice. Secure the hose some so it don't flop around and spill out onto the floor. I used a semi clear bucket with measuring lines on it so i knew how much to add back in after a start. Just let it run for a few seconds shut it off than look under to check amount in bucket. Have plenty of new fluid ready and will take a few mins.
The fluid runs out at a kinda slow steady pace no need to get in a rush.
Overall easy job.

1) yep very doable alone, done it myself!
2) it comes out steady as stated for a few seconds. i pull out 2 quarts at a time (as said in the link too) and that gets displaced out in about 10-20 seconds if i recall correctly.
3) disconnected line is a return line so nothing should come out. i do put it inside a water bottle or other catch can to catch residual drips.
my first flush i used 10 quarts until i saw the fluid become transparent red. this was at 130k and was never serviced until i got it. yours will vary depending on mileage.
