Here I change the oil in my transmission: LA125.
Here's a link to a video I made on "How to fix a Hydrostatic Transmission that slips on your John Deere.

[@dpo1867]

Nice work on the video. Good to see we can still get down on that darn concrete floor to fix something and walk away for lunch... LOL. I see some are adding drain plugs to allow easier oil changes. I guess one advantage is you can crack the case open and change the oil filter and inspect inside.

[@Foomba]

By far the best video of this type. Each step taking apart and putting back together clearly explained and filmed. Great job!

[@WeekendHobbyMechanic]

Thanks

Thanks, appreciate you taking the time to redo your video. Really helpful!

[@ColinWatters]

My Toro has a nice little header tank to which you can add fluid but grrrrr no drain plug. It was such a delight spending a whole day struggling to get the transmission off the mower. The fluid came out looking like coffee :-(

[@feliperigau7353]

EXCELLENT!! FLAWLESS!!

[@WeekendHobbyMechanic]

Thank you kindly!

[@ColinWatters]

Just drilled mine today. The metal isn't very thick on one of them so won't be many threads when I cut them tomorrow. Must be careful not to over tighten. The outer surface of my case also has a fair texture to it so I decided that needed to be flattened off a bit or will need a very soft washer to seal it.

[@JohnSmith-uy7sv]

I watched terrell fixes things and he said the 2 marked spots under the tranny you can drill and tap. It's not that hard, but I would just do mine as it stands. UP on a ramp so I could get to the 2 spots and drill them out and then tap them and put in the square head plugs. He said it is there for each manufacturer if they want to put in a drain plug or not. It is all up to the company that makes their mower and uses their trannys. 🙂

@@ColinWatters I think youtube is hiding comments back to me. I've been scrolling through the comments and as I go up and down the more show up from 7 days ago or more and nothing was there before. So, you did not go by what they recommended? How did you fill it back up with oil and what kind of oil? synthetic 10w40? I forget the name.I've seen others recommending synthetic oil. but my small yard is very little and mostly flat in south florida. a little sloped in the back 20 minutes cutting and 20 in the front all flat. nothing steep. sorry about the return.

[@ratpatootie8623]

Honest question. Has anyone just made a drain hole on the bottom? Tap and plug it? Damn, that’s a lot of work to change out oil on that gearbox.

Yes. Watch this video. m.kzbin.info/www/bejne/Z5rOeKRooJmcgKs

[@WeekendHobbyMechanic]

Vernier calliper. You can use a small ruler.

[@skiprope536]

Bravo man. TY. Putting dogs on . Got beers in the fridge frosted Pilsner. Now get over here and do mine. I will assist. Serious question…how many hours on your first chance of fluid.? I have 480 hours on mine (k46 locking diff). 13 years old. Should I change it or leave it alone?

[@WeekendHobbyMechanic]

I have one here with over 500 hours. The oil was in good condition, no metal flakes attached to the magnet. It all depends on how the tractor was heavily used. The manufacture says change your oil every 200 hours.

[@ramchillarege1658]

Thank you. This is easier to follow. And I need to make a list of the order... unless, you want to post a few bullets off the top of your head!

You don’t have to get that technical with the fluid level 30 millimeters off in either direction doesn’t even matter

will any 5w50 work? im not sure about anything to do with transmissions and tuff torq branded oil is way to expensive

[@WeekendHobbyMechanic]

Has to be synthetic. 10w-30 works too.

[@webtechaz]

i have a d110 i bought last week, has 200 hours, mowed the lawn twice and now it wont go up the hill. drives on flat lawn fine. do you think doing this will help. No way im paying 1k for a new tranny =(

[@WeekendHobbyMechanic]

Did the previous owner said it has a bad transmission? I’d call him for my money back. A heavier oil it will help.(15w40) But once a transmission starts to slip it will need replacing. Have a look at this. m.kzbin.info/www/bejne/aXXCp6eDnJKNrsk&pp=ygUlVHJhbnNtaXNzaW9uIGpvaG4gZGVlcmUgd2Vla2VuZCBib2JieQ%3D%3D

[@reggie2334able]

Is this the same procedure that you would use for a John Deere L1 11 lawn tractor?

[@WeekendHobbyMechanic]

No. Different The L111 drain plug is at the bottom of the transmission. The fill cap is near the top, front side.

[@reggie2334able]

@@WeekendHobbyMechanic thank you

[@carltonleggett8222]

I have a JD LT133 do you think this LA125 is similar? Mower purchased in 1997 and never replaced my oil. It is slipping a little on uphill pulls. Could be a loose belt but needs oil replacement for sure.

[@WeekendHobbyMechanic]

Remove / install is a bit tricky. Watch this video. I would install the forward/reverse rod on the transmission first and then lower the tractor down. You can start watching it at 14mins in. m.kzbin.info/www/bejne/aXXCp6eDnJKNrsk If your transmission is slipping or slowing down I’d replace the filter.

[@tearnyscribner9146]

What is the black screw on type cap that's right above the drain cap with the magnet u used? Does that cap come off? Looks like it is a full cap

[@WeekendHobbyMechanic]

Vent cap. If it pops off, u can use a bit of silicone glue it back on.

Thanks for the video, I'm doing my first one today. Would you suggest first to change the fluild in it first or just get another rear end? I have a JD D130, new belt, and it starts to slips after it warms up. I've taken it out, now I'm at the point where I should change the fluid or change the rear end completely. What's your suggestion?

[@WeekendHobbyMechanic]

Add 15w-40 or 15w-50 oil. If that don’t work maybe start looking for a used tractor “in bad shape” with a good transmission.

[@mrbubetube]

@@WeekendHobbyMechanic blah, that's not music, it's computer generated noise. it's your video and you can do it the way you want of course, I'm just making a suggestion as a viewer, but when you're doing a demonstration or an instructional video, any audio or video effects you add that have nothing to do with the demonstration, it only serves as a distraction to the viewer. it's an attention divider. Do you want the viewer to focus on your demonstration, or listen to music? trying to do both at the same time diminishes both. I know the TV commercials, TV shows, and movies do it, but you're not doing a commercial or entertainment video. You want your viewer to think and learn what you're showing them. Playing music just makes that more difficult and adds nothing to the demonstration.

my tranny is the K58 and about 330 hours. Do you think it's time I drilled out those 2 spots under the trany, drill and tap them. No way I'm doing all of this when it's easier to drill and then tap and you can pour gas in the top plug to clean it out. But I know, you probably can't get to the magnet on the top cap. That is just soooooooooo much work. 🥰

After seeing this video, which was well done by the way. I needed to change the transmission fluid in my 20 year old LT166. I also was replacing the cracked fuel tank. once i removed the fuel tank, 3 bolts and the fuel line clip, the whole transmission was exposed to my surprise. The filler cap was right there. Removed filler cap and used a fluid suction tool and it worked great. refilled fluid, put tank back on. super easy. FYI to you all. 🙂

But then its a tight fit for the funnel to fill it back up. Do the drain plug. Then you don't have to do that all over again in another 300 hours or so. How many hours were on that change??? Thanks.

Just did seals on the LA110. Check the axle washers closest to the transmission the spacers actually pressed the inside of those washers into the seals cutting them to shreds. Put thicker tsc 3/4" washers on to fix it. If you don't care about the looks of the mower you can remove the seat spring bolts and lift up, remove gas tank and you have access to the top of the transmission, it just gives you fender flares. 😂 Thanks for the video!

[@richardw4132]

Great video!! What are the initial driving symtoms before the transmission pulley fails? I have over 200hrs on my JD130 lawn mower. I just replaced the main drive belt. I have noticed there is less and less power while going forward or in reverse. When I raise my foot off the gas pedal it seems to regain some power but not much it then gets slower and slower. Would the transmission pulley be a likely culprit?

[@WeekendHobbyMechanic]

Does it work better at 1/2 throttle? If so I suspect the filter is starting to plug up in the transmission or it’s low in oil. Any leaks? The bottom pan needs to come off. Watch this video on how the remove the pan. Just replace the filter. Add silicone on both surface when putting it back together. m.kzbin.info/www/bejne/aXXCp6eDnJKNrsk&pp=ygUeUmVidXVsZCB0cmFubWlzc2lvbiBqb2huIGRlZXJl
