How to Fix a Transmission Leak in Your Car (Axle Seal)
How to Fix a Transmission Leak in Your Car (Axle Seal)

one, two, three, four! Rev up your engines! It’s time for the Scotty Kilmer Channel,
Today I’m going to show you how to fix a leaking transmission in your car,
now in this case, it was easy to figure out what was going on, because it was losing transmission
fluid, and leaking on the bottom,
so we’ll jack it up and check where the leak is,
now transmissions generally leak in one of three places,
either the pan is leaking in the gasket, in this case it’s dry, so it’s not that,
or the front main seal of the transmission, which is a real job,
because you have to pull the transmission off of the car,
but that’s still dry, and the third place they often leak,
are the seals where the axle shaft goes into the side of the transmission,
which is the case here, we can see it’s all wet,
now the seal it’s is no big deal, there is one on each side,
but we have to take all this stuff apart in order to get the seal off,
so let’s get going, first we take off the wheel,
then we have to take the tie rod off, we’ll take the but off,
and here’s a trick, you get a big sledge hammer like this,
and hit it, off it comes,
then we take off the nut that holds the axle shaft in place,
off it comes, then we take off the nuts and bolts that hold
the hub onto the strut, then the axle wiggles out,
we have to go behind and pry it out, you just get a good pry bar, stick it up against
the inner axle shaft and pull, and after a little wiggling,
out it comes, then you go to the other side and finish pulling
it out, out it comes,
and here is the seal right here, we’ll just pop it out with a seal puller,
very handy tool, just fits right in there and pops it out,
and here is the old seal, and the seal puller tool,
you can get it at any Auto parts store, then you get the new seal, get yourself a
little extension for a socket, and you can hammer it in all the way around
the edge with a hammer, first you place the seal in the hole, so it’s
flush, then you tap it in, working the whole way
around until it’s sealed the whole way in, now here is a trick I learned years ago,
there’s a little clip on the end of here, and they have a tendency of falling down and
getting stuck, so you get a tub of grease,
then you stick it on the end and pull it off, the grease will then hold the clip in place,
so when you put it in the transmission the clip won’t get stuck and break,
then you just place it in the hole and tap it in so it snaps in place,
then you just assemble it all back together again,
put the shaft in the hub, and bolt the strut back on,
now of course, I’m going to put a seal on the other side too, because it was starting
to drip, they are both going to wear about the same,
but I’m not going to show that, because it’s just the same thing,
only on the other side, and of course, remember to check the transmission
and fill it up for the fluid that was lost, so the next time your transmission seal starts
leaking, why not replace them yourself, and remember if you have any car questions
just visit the Scotty Kilmer Channel, and I’ll answer them, as soon as I get back
from paradise, assuming I come back

    Whats up Scotty! So i have an 01 Hyundai Elantra and just recently it started leaking quite a bit of transmission fluid onto the ground. The thing is, it seems to be pooling at the top of the transmission and then flowing off. I havent dived into much yet but do you have a clue on what the problem might be?

  2. canada painter says:

    Scotty,Is it possible to weld in the transmission tube seal hole? I put in already 2 x new rubber seals but still leaking although I covered it with silicon tape, white gas pipe tape and it is still leaking. I AM TIRED OF IT. so I want to weld the hole in for once and for all.

    took my truck for an oil change. The tech at Walmart noted three things. PG 141, TQ 15 and transmission leak PTS. I kinda get the transmission leak but what about the other codes what are they and how do I fix them? Thanks for any help.

  12. Kelly Atkinson says:

    Would you expect all the transmission fluid to come out when you are changing the seal?

  21. Kal co says:

    Hey Scotty Kilmer I had a question, I have a 2012 Honda Civic LX. One day I noticed my transmission was leaking. Sure enough I found it was leaking from where the CV meets the transmission. So I replaced the seal, then about a week or two later it started leaking so I replaced the seal again. That was two or three weeks ago. Today I looked at the street and saw transmission fluid again. I have 2 thoughts it's either the CV axle or the transmission. I would really appreciate the help if you can thank you.

  53. rock says:

    How do I know if it is my Trans leaking?

  54. Spex says:

    Scotty Kilmer
    I just had my transmission fluid changed. Before, I had no leaks and a few days after, I noticed my CV Axle Seals were leaking.
    1) Do I need to hold the mechanic accountable? Did he do something to cause this? Car is 8 years old, but only 68,000 miles on it. I just find it odd that everything was bone dry before the tranny flush and now I have a leak.
    2) Only 1 side is leaking. Should I replace the seals in pairs or just the problematic one?

  55. P3DRO says:

    Do you have to drain out the transmission fluid before taking off the axle??

    Quick and simple explanation, is pretty similar for most cars, some will have an intermediate bearing which is held in with bolts, most french cars have this and it's fiddly, just an extra step to remember.

    Question for you I brought my 2006 Porsche Cayenne. V8 to a mechanic to change the transmission seal in the front as it is leaking from the seal he says in order to change the seal he had to take apart the top of the engine and go from the top of the engine to remove the transmission so that he can get to the seal does this make any sense to you.?

    Is it needed to drain the transmission sump previously, or I can take the trasnaxle out of the car that it won't leak a lot of fluid?

  86. boyleheights12 says:

    Hi Scotty, from your video and public comments I can tell you are a very experienced mechanic. Please help? Today the gears on my 1999 Toyota Camry went haywire. I stopped at gas station and suddenly wouldn't get park! I think friend put on reverse to make it drive, and could only stop car with hand brake! Does this mean transmission is broken? Had enough oil and hadn't noticed any oil leaks except it would accelerate on its own sometimes or have hard time going up hills. Any advice appreciated 🙁 .

  91. HJ says:

    My car started leaking transmission fluid at 150,000 miles ('09 Ford Fusion, V6). I've just been adding more every couple weeks when it gets a little low. I'm now up to 185,000… maybe I should get that fixed.

    Hi Scotty, I have a Toyota Kluger 2009 and it's leaking engine oil. When I turn the car on the engine oil start pouring out (not dripping) but when it's turned off the leak stops. The leak is located under the driver side near the front. Where do you think the leak is coming from?
