Transmission Fluid Change Question

[jaywidhalm]

So, I plan on changing the tranny fluid in my 08 Sunsport while winterizing this year. My question is this. While hooked up to a fake-a-lake can you put it in gear to spin the transmission to stir up the fluid prior to the change? Is this even necessary? It hasn't been ran in 3 or 4 weeks now, just want to get out any contaminates that I can. Will this hurt my drive shaft seals or anything not being submerged in water?

Thanks for the advise guys...sadly, summer is coming to a close for me.

You should never spin a DD of VD out of the water . Its very hard on the cutlass bearings.

That's what I was thinking. Will running it out of water in neutral stir any of the tranny fluid, or only when it is in gear?

How far away from a lake are you? You would be surprised how running the boat and getting everything up to temp will help out. I run mine up to temp and then trailer it back about 10-20 minute drive depending on the launch I use and traffic, then it is about another 20 minutes or so before I start pulling fluids and they are still plenty toasty when I drain them.

Best to change with warm fluids.

Yeah, I am about 20 minutes from a launch...was just trying to avoid that ordeal since I already have a fake a lake so I can get the oil up to temp. Oh well, one last trip it is...I may have to do a ski run while I am out!

The fake a lake will still come in handy for after you change the engine oil and filter. Always a great idea to run it and circulate clean oil once more before the lay up.

I start at the lake - always need one last ride. Head home for the fluid changes. Then recirc some oil. Then start the winter layup process.

Yeah, that's true. I always circulate the fresh stuff before she sleeps for the winter.

I'm not positive in this but I believe the fluid still flows as long as the boat is on. The flow depends on Rpms and the gear it's in. But the fluid should cycle even though it's not in gear.
