CD28 sloop transmission oil change advice sought

OK, we've paid the hospital the bill for the back operation and the replacement of blood lost through the knuckles. I'd like to see a description of how one goes about changing the transmission oil on our beloved 28. Thanks!

Sue, What type of engine? Gas or diesel? We have a reverse gearbox on our CD28 Volvo Diesel which we had to improvise with a plastic hose and funnel to change - a two person job. Is this what you're talking about? If so, let me know.

It's an M18 Universal diesel. Very silly of me to omit that bit from the post.

Sue,

If I were to do it, I'd remove the fill cap from the front of the engine, lean in over it carefully, remove the cap, and suck the fluid out with an OilBoy oil changer.

The real question is, WHY? It's not like changing engine crankcase oil. It's not a required routine maintainence. Transmission fluid should last the life of the tranny.

I would think draining the fluid out from below would be almost impossible, access is so restricted, you would end up dumping it into the bilge, and your vessel will smell like a tranny shop from now on.

If you are really set on doing it, suck out what you can with the OilBoy, replace what you remove, and seal it up.

Unless the oil sump (engine or tranny) is set up for draining out of the bottom, you have to suck it out thru the filler hole. The electric pump is easist, letting it run and "poke around" trying to allthe old oil in the bottom. Same procedure as w/ the engine via the dipstick hole. DONT LET ANYTHING FALL INTO THE FILLER HOLE! That will ruin your day and could ruin your transmission. Depending on access (lay over the engine???), could try pouring from twist off bottle directly in or get a length of clear vinyl hose (aquarium) and a funnel that the hose will push onto and run the hose into the filler and the funnel out where it easy to pour. You might even find gear oil in a plastic container w/ a pointy spout that can be cliped off to different sizes (squirt directly in or into the vinyl hose.
Change the oil hot to get the contaminates into supension. Tranny oil does not get contaminated by combustion blowby but will get metal particles (gear/bearing wear), water (condensation/raw water cooling), etc. Does not necessarily have to be changed every year, every once in a while, if you want the transmission to last. Dependant on usage.
