- This is my journey for optimum honda transmission fluid. I tried several fluids and found the factory Honda 08208-HST02 Hydrostatic to work best. I explain my experience and show results of fresh factory fluid.
Understand this, there is no leprechaun riding a unicorn to oil company mixing a special cocktail for 2cycle oil. All the oil derive from same stocks just different qualities. Its about diluting properly for 2cycle to burn. If you put to much "2cycle oil" it smokes. 2cycle oil comes from same stock as 4cycle oil. Its just been colored and labeled "2cycle oil" and you pay more for less.
Look inside 2cycle you will see a piston, cylinder, pushrod,crankshaft! Same thing inside of high-performance engine. So use the best oil you know for the job.
If you’re going to use regular motor oil for your 2 cycle engines like they did 50 years ago, you need to mix it using the ratios they used 50 years ago. 25:1 or 32:1. Modern 2-cycle oil is formulated differently than conventional motor oil - don’t try substituting 2-cycle oil for motor oil in your car or expensive 4-cycle engines, you’ll quickly learn it’s not the same thing with different labeling.
My transmission has been running for over 17 years, same fluid.
Sir, great video to help home mechanics! I'll buy the Honda Transmission Fluid. My mower is over 12 yrs old and has about 300+ hrs. Transmission is fine but I'm going to replace it. I use M1 10w30 High Mileage oil and change it twice a year. I believe that one secret to mower life is to keep the blades sharpened. I change blades same time as oil change. I also clean under mower each month. Doing this cuts down strain on thick grass. I have the 190cc engine and use it to mulch 2 large pin oak leaves every fall. I have not raked leaves since 2012!
Thanks !! I went to my small engine shop and asked for a common old motor that I could disassemble and learn. He gave me a HRX 217 HXA !! No self-propulsion and won't run unless on 'choke'. $700 new ! But the owner just bought a new one rather than repair. Leaky seal on the shaft may fix transmission. Carb cleaning should fix idle. I DON'T LIKE OUR THROW AWAY CULTURE !! THIS WAS THE ONLY VIDEO I COULD FIND ABOUT RE-FILLING TRANSMISSION.
The rest are all 'remove and replace ($245). THANKS !

great detailed explanation. Thank you for sharing.
Good info thanks. Hey, fwiw, Yamaha in their Hydrostatic transmissions they call for 10w-30 Diesel Oil. That may be another option for people not wanting to buy the Honda HST oil. Guess I just like when companies don’t sell their branded stuff, but give you a oil spec that lets you buy what you want.
Two good tips. Thanks 4/29/2024
Thank you sir. My mower is running slower. I’ll replace fluid with the Honda original and see if that helps.
Damb thanks for the drilling the hole in the discharge chute idea. I got the same mower 2018 used almost a month & my Husqvarna Hu800awd was fixed. So the Honda went in the basement until late last year just to run a tank of gas threw it, then back in the basement. I have to change the belt on the Husqvarna AWD. Yep the Honda would clog up. I do 23 yards per week with the lil mowers.

This guy is talking sense. 👍🏻
Check this video out. It about bearings.

Thank you brother
Is the nut on the top pulley normal thread as I am struggling to free it. Great vids btw
nice video ty
Just looked underneath. There are two connected units, one is a pump. Both have drains that are hard to get at. The fluid must go between both, I would think.

Somebody gave dimensions of the seal on the shaft. Was that you ? I have a very leaky seal. So oil all gone. I cant find its capacity because it is "not serviceable"... but you and I know better !!!
Do you have a video showing his to change the transmission fluid?
Honda hrx217hxa hydrostatic
maintenance
Is there a danger to running the old fluid for an extended period if the mower speed is satisfactory? My HRX is original from 2009 and has never had the hydro fluid changed. I hate to tear into it unless I need to. However if swapping fluid will extend the life then I’ll do it.
The way the system works is hydraulic pressure. In order to keep the pressures high tolerances need to stay tight. Old fluid doesn't provide the needed friction reduction to insure long life of the unit. Best to maintenence change it while it's working great rather when it starts slowing down. The reason it's slowing is because it is looking it's viscosity. Oil breaking down and not providing the friction resistance to reduce the wear. I would change it it it has been in service for a few years just to maintain the unit. Just know to buy a new unit is $150+ vs $15 for a bottle of hydrostatic fluid.
What's the difference between 100% synthetic and full synthetic? Other than the fact that in your example at 3:25, one was motor oil and one was ATF.
Full synthetic *example* 80% conventional regular oil 20% pure synthetic oil.
100% pure synthetic oil is all contents inside of bottle is synthetic oil.
So full synthetic mixes regular and synthetic oil. Yet when used in duty situation the conventional oil breaks down faster.
Conventional oil may evaporate flashpoint at 350°f and synthetic at 500°f. Using air cooling engines that idle at 325°f no load. Then when loaded temperature increases significantly especially if it 2cycle the rpms can go up to 9,000rpms producing even more metal softening heat.
That is why I use 100%synthetic even in my 2cycle. I sold an lawn mower oil change to a neighbor. He was standing right there during engine warm, oil drain and refill. When engine started, it was ruff at first because of old conventional oil. Once the 100% worked its way around internals. He even noticed how smooth his briggs and stratton started running.
Hi Thisls, my 10 years old HRX2173HYA trans still runs strongly but it gets hot after 1hr running (I found that while try cleaning grass cake underneath) and can not touch it, no leaking oil (very dry axle). I need your opinion, change the fluid or replace the transmission?
Thank you.
Lets get one thing understood. I dont like spending money unnecessarily! So spending $300+\- for transmission on a $500 unit out? Since it is still strong cant go wrong fluid change $15. Next thing is the unit will get hot because it operates by means of hydraulic pressure. Anytime you create pressure the temperature will rise. Temperatures above 125f* will not be comfortable to touch. These residential mowers are intended to operate for about 30-45 min once a day once a weak for about 4months out of the year with the factory honda fluid.
I would invest in high quality 100% sysnthetic fluid. I used amsoil 20W-50 Synthetic Hydrostatic Transmission Fluid with my hrx217 and it became a duty mower. Duty is what you are doing by running it constantly for more than 45min a day, everyday. With the amsoil you have to let it warm up for about 5min then it is ready for duty work. I would recommend 100% synthetic engine oil also. The regular conventional engine oil not really a duty oil especially in these air cooled engines.
Check out this video. Start at the 4:17 mark. It shows engine temps at free spin. Once you load it with grass and self propel. The engine temps rise significantly

@@thisismee3642 thank you for your opinion. You are very nice and very helpful.
Hi pls use 10w 40 , reason u got problem is because u used 5w. i am planning to change transmission fluid with original honda one, how many times i have to cycle the drive lever while filling the oil, i am planning to use impact gun to rotate and cycle the lever at the same time, will 6 times is sufficient enough.. any tips is good
I dont have the hrx anymore. I sold it for the hr215 model with gear drive. U cycle tge lever about 5 times. The purpose is to remove the air from system. Air causes bubbles, air can compress reducing the hydraulic effort.
I appreciate your nice videos. What is the transmission oil capacity. Thank you.
Not exact but its around 8 fluid ounces
@@thisismee3642 thank you.
I use Honda motorcycle 10/30 w oil recommend by Honda mechanic very shear stable
Have a quick question: I have 2 mowers. HRX 217 and HRR216. Should I used Honda hydraulic fluid for HRR216 or synthetic 10w30 oil? I'm servicing both mowers.
Also check my other videos for long lasting equipment advice suggestions.
If you use synthetic use 100% synthetic. That way all the contents is synthetic. When you use full synthetic. The contents may be 85% conventional/15% synthetic. And of course the conventional will breakdown first. Amsoil has 100% synthetic hydrostatic fluid. My experience with amsoil 100% syntheitc was I had to let it warmup first before it performed maximum. Once warmed up it. It becomes a duty mower.
Using the honda specific hydrostatic oil with be operational at startup but break down fast depending on use. If you only using your equipment for 1 20min cut per week 4months out of the year use honda fluid. That is not duty use of equipment. Still recommend changing the fluid after 2-3years of homeowner use.
If you cutting 3+lawns a day 4months out year then leaf mulching 1 1/2 months. Use the amsoil because you are using your equipment as duty. That is where the amsoil shines. I recommend changing the oil after about 1year of duty use to keep it fast and operational for your commercial business.
Once you get the hang of replacing the fluid. Its no question about doing it. Then it becomes harder to just buy new equipment because current equipment is proven with minor maintenance. Once minor maintenance smooth out. You really start to see your capital build because its not constantly being pushed out $800+ every 2-3years for new equipment
@@thisismee3642 This info in the video and your REPLYs is without a doubt the most valuable info on the Honda hydrostatic transmissions ON THE WEB. QUESTION: is the AMSOIL 20W-50 Synthetic Hydrostatic Transmission fluid you are using AHFQT in Qt.? For duty use, this sounds like what you are now recommending? QUESTION: to minimize cost for the 2 flushings prior to final fill, what do you recommend using as the fluid? I can get the AMSOIL for $11.25/qt. locally. (Mowing 2 acres 1x per week, 6 months per year in TN.; 3 HRX217 mowers, multiple transmission swaps, going to get this trans fluid maintenance under control..>!) Thanks for your reply in advance!
@@BruceAvilla amsoil 100% synthetic hydrostatic oil is for duty use!
let me correct this. My problem was using the synthetic "motor/engine" oil for the hydrostatic transmission. Because I was reading forums and people was saying they used 30w "motor" oil so I improvised and used 100% synthetic "motor" oil. It worked but intermittently. So at the time I switched back to honda specific hydrostatic oil.
Then I found that amsoil had 100% sythetic hydrostatic specific oil. I used that and what I found is I had to let the fluid warmup. Once it was warm/hot! It became a duty mower. I sold a hydrostatic fluid change to a lawnmower man. And told him warm up first. The mower became duty for him.
He wore out the blade clutch bearing because he didnt follow my instruction to perform maintence on key components.
@@BruceAvilla the purpose of flushing it is to remove the inferior oil residue to minimum quantity. Once you have flushed and filled with the 100% synthetic the first time. After that the fluid changes with be 100% synthetic to 100% synthetic.
I showed my momz after I switch her car from conventional oil to 100% synthtic. The cake buildup from the conventional breaking down. I replaced the valve cover gasket and made her understand the significance of 100%synthetic as it was loosing up the caked conventional
brother do you how to drain the old transmission oil out?
th-cam.com/video/2_t668pklTM/w-d-xo.html here u go
how do you fill and how much just bought a new hrn216vkaa...................does it have this transmission...........?
From the looks of the images matching your model number provided. Highly unlikely to have hydrostatic tansmission.
TIM, have you replaced the clutch drive cable on your mower?
Yes you have to remove the blade then the clutch to get to the cable under the mower. Its simple bu hard if you was paying me to do it so I could charge more. I recommend removing the removing from handle first if the cable is complete. Install at the clutch first when installing new cable
@@thisismee3642 The replacement cable comes with new control arm to replace the one on it. I was looking at yours while you was servicing the transmission. I will have to remove the tyranny to swap arms. TY for replying. Did you reuse the seals on drain plug and cap?
@@thisismee3642 How much would you charge for this job to replace cable TIM?
@M Gomez houston,tx. The lever for the transmission is not a closed loop. There is slit in the lever that I bend to remove that cable connection. Then refit the lever after cable is replaced. If yours is looped both cable and lever. I will not instruct how to remove cable for liability reason.
@@mgomez5606 if the seals are not leaking I would not touch them. You run the risk of scratching the shaft. That would nick the new seal.
Look up the part from one of the web sites. Buy from that site or cross part number with ebay/amazon which ever is in stock and you comfortable with
I have ahondar hrx217 the transmission is not working, there is no oil in it, do you think if I put oil it will work?
If there is no oil, then that means you have a leak. You have to put oil in to find the leak. That is when you test it. Ince it is filled. Put a locknut on the shaft for the pulley. Spin with a drill, engage the metal lever(with the spring on it) activating the self propell if it still works the output shaft will start spinning. Output shafts spinning, it works, now find out if there is a leak and fix it.
@@thisismee3642 Don't have leak but my HRX is slowing down. Bought some Honda fluid & drained the old stuff per your other video. Refilled to the top & bled per a Honda Service Page which said to engage the control arm while turning the input shaft clockwise. Then rotate & turn the unit until there are no more bubbles.. Reinstalled & mower runs a bit faster but still weak. No movement at all at the lower speeds on the lever. Any advice? BTW, thanks for your helpful videos.
@@jjparody8257 engage the self propelled lever. Lock it in place. Make sure the speed adjustment is max speed. Then turn mower on side. With air filter up. Now check to see if you have more movement on the transmission lever. If so, make adjustment to the cable so that there is no play at trans lever.
These operate off of pressure, so that little play could slow it down. Like when you adjust the speed at handle.
@@thisismee3642 Thanks for the quick reply. When you say "transmission lever" I assume you mean the control arm on the transmission. I did have a small amt of play so I adjusted the cable up as far as it would go. This improved things somewhat so far. With the orange lever at full speed, it provides a nice pace but before it would run away from me at that speed. I'm wondering if my cable, probably the original, is stretched. Have you seen that? Cables are not much $ so I could try that or maybe pull the tranny again & redo the fill & bleed.
@@jjparody8257 yes I respond if I get the message in a timely fashion and/or I have free time. Correct in your assumption about lever with the spring. The transmission is always on regardless if you use or not. That is why the belt is direct drive unlike others that pull belt tight for engage. Even if there is no fluid it pumps until you put fluid. So if you watched the video I went with that amsoil product code (ahfqt). Also my belt is like 2mm shorter than original factory.
The pulley on trans has a washer under it, which allows pulley to slip under loaded situations. I removed the washer, went to hardware store matched treads of nut holding pulley. Bought another nut, grinned down to like 4mm. Locked pulley to input shaft so not slipping. Absolute power engagement thats why my wheels spin. It just works for me.
lol you spun up the rear wheels on that launch at 4:51
How much oil You refil in transmission hrx 217?
Takes about 7ounces to fill, but you should have about a quart total. So you can flush out the old (1year pro use/5year home use) fluid properly and refill.
Check this video out, bearings
th-cam.com/video/pIaaLPOzvYg/w-d-xo.html
Is it posible to do it without taking off transmission? Tnx man for information...
@@bojandujmic2040no, because you have to be certain no dirt enters the hole.
Is one bottle enough?
You should have at least a quart of fluid on hand. You are going to run 2 cycles to flush out the the old beat up fluid. The third is to refill with fresh oil.
@@thisismee3642 Did you reuse cap seal or replaced it. I'm gonna do it on a harmony tranny and I know it has not been replaced. Plan on keeping it . Where did you get the oil?
I reused mined. If yours is in good enough condition then you could possibly reuse yours. If not then you may have to replace it.
