Late Model G23 transmission Oil Change

[artpicone]

Does anyone know of a posting or can they post how to change the transmission oil in a later model G23. I’ve searched the Forum and can not find any relevant posting. I have the 450hp ZZ6 PCM engine.

Should last a really long time without changing it. How many hours are on your boat that you think it needs changing?

According to the PCM Maintenance schedule transmission fluid should be changed once a season. It's pretty easy to do. Use an oil extractor and suck all of the Trans fluid out through the dip stick opening. Replace with recommended fluid and capacity.

You can find the manuals for your particular engine by doing a Google search or look here...

My 2021 PleasureCraft Owners manual says after 25 hrs and then yearly. I have 25 hrs on it.

Is that transmission or V-drive?

I’m wanting to change the transmission. But speaking of the v drive is that sucked out as well.

[greggmck]

Yes. Same procedure. It's easier when the v-drive fluid is hot to warm.

What Dexron III ATF do you use? Can I use chevron MD3 synthetic ATF

[greggmck]

By me Dextron III is not that easy to find. My Walmart stocks Pennzoil Dextron III so that is what I use. I would not use it if it doesn't specifically say Dextron III on the container.

I had similar questions about changing transmission and v drive fluid...Are you changing your v drive fluid every year as well? If not, what sort of schedule have you had your boats on? Manual says the v drive fluid is a "lifetime" fluid, but I find that hard to believe.

Good question. I have a G23 2017 with 465 hours and I have only changes the trans fluid one time.

The new schedule is to check/change v-drive fluid as needed every 100 hours and/or every season. I guess PCM is trying to reduce v-drive warranty costs.
