P1000 Sub-Transmission Oil change - Honda Pioneer 1000

[CID]

I may have mentioned this before but we do Honda Moly blend in our sub trans changes.

Even get Honda to pay for it on waranty rebuilds. 😁

Yep

 

[Spoonbill]

Mobil 1 Racing 4T can be and is used by me in the Subtransmission

Thanks for the heads up. WHat do you recommend for the SUb Tranny over wide temperarure variance. We run from below 20F to 100F

Belay that inquiry; I scrolled back a few poss and located the answer; 10W-40 I’ll try the 10W-40 or 10W-50 (if available)

Note that the sub trans doesn't spin until you're moving, so warming up the engine isn't warming up the sub trans - don't take off like a bat outta hell, give it a bit to loosen up at those extreme temps. That's also good for wheel bearings, diffs, etc.

The Pioneer 1000 is a little different from your past Honda ATV or SxS's. With the 1000, there are 3 different categories that need to be discussed when changing the oil. We will try out best to cover them in detail. The idea is to help you complete the oil change at home on your own vs paying a dealer $$$ to do it!

1. Engine Oil and Filter
2. DCT Filter
3. Sub Transmission

See Engine and DCT oil change guide -> HERE!
In this thread, we will ONLY be discussing the Sub-Transmission Oil drain and fill.
***WARNING - DO NOT DRAIN THE WRONG PLUG!***
Before we start it is important that you locate each drain and be able to tell which one is for what. There is 3 drains and they can be easily mixed up causing you draining the wrong one!

Tools needed:

• A 17mm socket & ratchet.
• Drain Pan to catch old oil.
• Few shop rags.
• Funnel with extended tube to reach into the fill hole. I use a version of this funnel from Walmart, it lets you turn the flow on and off as well as measured calibrations on the side: FloTool Measu-Funnel, 7pc - Walmart.com

Required Oil:

• The Sub Trans requires the same type and weight of oil as the motor and DCT.
• Recommended Oil - Pro Honda GN4 10w30, 4-Stroke Motor Oil - Buy Here
• 1.27 US qt (1.2 liters) upon draining.

Additional parts you may need:
Note: Honda says replace the crush washer each time, most people do not!

• WASHER, DRAIN PLUG (14MM) Part# 94109-14000
• BOLT, DRAIN PLUG (14MM) Part# 92800-14000

Prepare the work area and the SxS:
Locate a safe and level spot to park the SxS.
DRIVE the SxS long enough to warm the engine. Around 5 minuets.
Drive to selected level spot.
Insure SxS is in park.
Turn off and remove key

Step 1: Remove the seat bottom where you will then be able to see and access the Sub-Transmission oil check dipstick / oil fill hole. It will be just off center more towards the passenger side for access and refill. Clean all dirt away from around the dipstick and remove it to improve draining oil flow.

Step 2: For draining the Sub-Transmission only remove the drain plug noted on the far left of the below image. It's bolt head is bigger (17mm) than both the Engine and DCT drain plug head (12mm) size. Situate a drain pan below the Sub-Transmission plug and remove it to drain the oil.

Step 3: Once all oil has been drained replace the drain plug using the same 17mm socket.

Step 4: Fill the Sub-Transmission with approx. 1.27 US quarts of specified oil using a suitable funnel.
Note: Sub-Transmission uses same type / viscosity oil as Engine/ DCT.

Step 5: Insert dipstick, (do not screw in) remove and check oil level, ensure oil level is between the high and low marks on the dipstick add oil as needed to achieve proper level.

Step 6: If oil level is OK screw in dipstick and re attach seat base. Mission accomplished!

Now you are all set and ready to hit the trail.
Good luck and be safe.

How often is this recommended for?

 

[Wellzy]

Front and rear diffs, along with sub transmission every 2 years I believe

 

[Robobrainiac]

Just did my sub trans for the first time today at 1400 miles! Thank you @JACKAL for the wonderful write up and Thank You @Hondasxs for the foundation of all this wonderful information!

My sub-transmission makes a lot of whine. For my first service I drained all 3 drains. Filled sub-trans with synthetic 75-140 and engine/dct with honda oil. Is quieter now. If sub-trans is just a gearbox, why put engine oil in it? Will let you know in a few years if it has any effect.

UPDATE: Thick gear oil in sub-trans is a no-go. Gears grind like the oil is holding the gears from shifting on the shaft. Oh well. Had to try. After 5 miles changed it back to Honda specs.

Wonder how 75-90 do sub transmission

Wonder how 75-90 do sub transmission

Way too thick! I imagine shifting would be tough in the cold or everything was completely up to temperature. 10-30 seems to work just fine.

So what do you use or recommend I see people using 10-40 royal purple or the Mobile 1 stuff I am fixing to change all my fluids and I just want something better in the sub transmission

 

[Prntckt]

I switched to Mobil One synthetic 10-40 in my subtransmision over two years ago and almost 8000 miles ago without any issues. I think it shifts from high to low easier especially when cold

Mobil 1 and Royal purple both make a great product, just stick to the recommended weight range and specs. But I definitely wouldn't want to run gear oil in the sub trans.

Wow! what a great procedure guide you posted for these oil changes. So helpful.
Is this still current for my 2021 Pioneer 1000-5?

Is the 10W-40 you mention a fully synthetic??

I’m guessing it would have to be a 4-stroke Motorcycle 10W-40 Synthetic?

 

[Dirtstiffs-1000]

Mobil 1 4T Racing 10w- 40w, full synthetic. Look at your other thread question.
