Checking Trans fluid...

[lay-a-wake]

We just got our hands on our first boat a couple of months ago, a 2007 20V, included a pic. I have been trying to go through it inside and out and learn all i can. I started trying to check the trans fluid and found two dip sticks? Im hesitant to say they are both for the transmission fluid checks, but Im not sure so i attached a pic of that as well. While on the subject of checking trans fluid, whats the best way to check it? (ex: in water, out of water, engine hot or cold? stuff like that)

They are both for the transmission

They are both for the transmission. "A" is for the transmission and will take any ATF type fluid or have been told any SAE30 weight oil also. "B" is for the V-drive transmission and will take a SAE30 oil. I think they take around a quart but that is just a guess without looking at my paperwork. When they originally came out of the factory it was recommended to use ATF in both of them but due to a high whining sound in the V-drive they switched the recommendation to a SAE30 oil. Or at least that is what I was told by the tige factory. It is easiest to use a fluid evacuator to suck out and then refill. I think there is a spot for cold or hot on it just like a vehicle.

More detail: You have two driveline components beyond the engine. The one nearest the engine, with dipstick A, is the actual transmission - the thing that shifts into forward and reverse. The one farthest from the transmission, with dipstick B, is the v-drive - basically a set of bevel gears with no external controls.

You should consider these two components as separate pieces and service them separately. They may or may not take the same fluid, in the same amounts, have the same service schedules, etc. For example, on my boat, the transmission uses Dexron III that should be replaced every 50 hours, while the v-drive uses something else and its fluid never needs attention unless it gets low or contaminated.

As for the details of service, that is entirely dependent upon what transmission and what v-drive you have. Each should have a plate with its manufacturer, model number, and serial number. I would start with that data and research what the manufacturer recommends. It's common for transmissions to want their fluid level checked while the engine is running, for example... but that's not true for all makes and models. You really have to look it up based on the equipment you have.

I'm glad to hear that you are digging into the details. That suggests you will be a conscientious boat owner. Remember, "Take good care of your equipment and it will take good care of you."

Good luck and report back, this is a very helpful site with a great crowd of supportive members!
