Help!! Water in the transmission fluid

[dead pair]

I have a 2001 SAN, and am trying to change the transmission fluid myself-- anyway, I found water in the transmission fluid. Any ideas of what I need to do, and how it could have happened? Thanks in advance!

Usually, if water gets too high in the bilge, it can get into the transmission.

I have had to deal with this issue on a few boats. Get the fluid warm by running the boat. While the boat is running shift in to forward, reverse, and back to neutral. Be sure to supply water to the raw water pump.

Suck out the fluid. Put new fluid in. Run the boat again, shift it again.

Suck out the fluid again, put new fluid in. Run the boat again, shift it again.

Keep repeating until the fluid coming out of the transmission is a clear red color. Not cloudy, that means you still have some water in it.

You can reduce the number of times you need to refill and drain the transmission by disconnection the transmission oil cooler oil hose from the top of the transmission, and blowing air into the hose, This pushes the dirty oil in the transmission oil cooler back in to the sump of the transmission, and you can suck more of it out.

Sorry to reopen this late post but Im curious how to "suck out the fluid". I have the same problem and am not sure what steps to take.
Thanks in advance for the assistance.

Jim, use a drill pump or other similar tool and suck the trans fluid out the dipstick hole in the top of the trans.

If your going to own a boat buy a Moeller extractor. It will pay for itself 100 times over

Be sure to make something like this to ensure you don't lose a piece of hose into the gallery as has happened to several on this site.

People have had pieces of tubing come off and stay in their transmission? Yikes!

What size copper tube is that? Thanks

Several...and it is costly.

It is 1/4" copper tubing. The hose is 5/16 od x 1/4 id so it slips over the copper. IIRC, the suck up has a 3/8 od x 5/16 id hose...it will slip over the first hose i mentioned. you can use two inch long or so segments of each hose size to step up hose sizes. Avoid bending the copper too much, it will kink and/or break.

Thanks! I did'nt see your reply yesterday in time and went ahead and siphoned a quart out using my old 12' long 1/4" id tube and shopvac to start the siphon. I did a quart last December when we got the boat and after reading this thread did another quart. Probably doing this once or twice a year is not a bad thing.

Do the ends of the vinyl tubing just get brittle and break off or do people lose short segments of hose down into the transmission?

I REALLY need to just break down and buy a Moeller!

All of the above and more.
