I would recommend that all of the upgraded parts for the low/reverse gearset are replaced while you have everything open.

This is the parts list I had for my repair:

Gasket, Sub-Transmission Case (21206-HL4-003)
Gasket, Sub-Transmission Cover (21205-HL4-003)
Shifter, Low Reverse (23751-HL4-AJ0)
Gear, Reverse Drive (23691-HL4-AJ0)
Shaft, Reverse Idle (23711-HL4-AJ0)
Center, Gearshift Drum (24331-HL4-010)
Shaft, Shift Fork (24210-HL4-010)
Circlip, Outer 14mm (94510-14000)

You'll also need two quarts of oil to refill the sub-trans when you got it back together.

I think that covers it. Let me know if you have any questions or feedback, or if anyone thinks I am missing anything!

So will these parts up date the sub transmission to the current sub transmission that the 2022 pioneer has and who does work like this besides the Honda dealership I would like to update my sub transmission

Essentially, yes, these parts would get you to a 2022 spec sub-transmission. Particularly this parts list would address the low/reverse shift and idler components and failures. Note that I did not install the updated high and low gears in my install, to technically completely update the sub-transmission to 2022 specs.

As far as who does this kind of work, essentially any competent mechanic who is comfortable with working on machines of this nature.

Would you recommend doing high and low gears or just doing the other upgrades would be okay since the upgrade you did is what’s causing problems

I think those are up to personal preference. I personally did not do them since they were not the source of failure I was trying to address (no reverse) and I opted not to spend the extra money on them and "rolled the dice" that the old gears would be fine. I'd leave this up to personal preference as I don't know that we have enough data to support that they "should" be replaced based on failure frequencies to the extent we have with the low/reverse components. The high/low gear parts were roughly $300 or so to purchase all four pieces. That was just the approach I took.

Theicor thank you sir!! I got the upgraded parts in my 2016 pioneer and am very happy with it !! Just got it done and drove around the block. Can’t wait to get in the woods and really put to the test.

I have to do this upgrade myself on my 2017 P5. What is the procedure for getting the subtrans. out? I have
looked everywhere and I havn't been able to find anything on it.

The shift star, and shaft should should be considered essential upgrades.
If you are running 27 or 28 inch tires the gear change is icing on the cake, if you are running 30 inch tires or bigger I would consider 22 reverse and high range gears a must do mod.

Does anyone know what's going on at Honda Parts King? I have emailed them and have not got a response?
I have called phone number and it goes to a some kind of medical facility.
