Transmission leak?
Transmission leak?
I took my car to aamco this morning because it was leaking what appeared to be transmission fluid. Well I just got a call saying that it was leaking between the case halves and that they would need to pull it out to fix it, so about $1400 and while they were at it he said he would recommend getting it rebuilt which would be $2500 altogether. What do you guys think? I have 109k and haven't even done the 105k service yet.
get some mighty putty and use it to plug up the leak.
The high pressure AC line in my Audi s4 developed some holes in it which ws covered by mighty putty
So is part of my oil pan.
That stuff really works.
Why are they suggesting a rebuild tranny? Are you experiencing any problems with shifting?
im just trying to corrolate how a leak = tranny needs to be rebuilt if your not experiencing any problems

I am not experiencing any problems at all when it comes to shifting believe it or not. It got a little low on fluid but I immediately filled it back up with the sufficient amount. No problems in the transmission just do not understand why they need to take the whole thing apart to fix it. Where can I get some of this puddy

The car is driveable I just have to keep fluid in the car, do you think I should check other local shops also? I already got approved for the loan but could easily just pay it off. I do not want to spend this money if it isn't "necessary".

firstly, I would NOT have Aamco touch your transmission.
Identify the leak and how big the hole is that its coming from.
Here is the product

you might be able to pick some up at Walmart. The one local to me has a section where they sell products advertised on television.
See if you can post a picture of where the leak is coming from.
Going to pick up the car soon. I will see if I can get them to show me the leak itself and then I will get it up. He said it leaks more when being driven. Ill get up a picture when I am home. Should i have the dealer look at it to see what they think?
if its leaking between the trans and block than its probably a seal thats bad.
Dealer will charge you just to look at the car. depending where the leak is coming from, you might be able to put some putty on it and be on your way.
I put this putty on my oil pan probably about 4-5 years ago and its still intact and no leak.
get the picture up though and we can better advise on a possible solution.
IDK why a "rebuild" would be recommended at all, unless you've got other tranny issues or the tech saw something after disassembling the case.

Also get an estimate including the "4" TB service from another shop/dealer, in case that will get you any sort of discount.
Our Odyssey (5AT) developed a leak between the case halves (with no other tranny problems
), and the repair cost at the Honda dealer was $1200+: the case seal kit was $220+ and included replacement of the engine mounts.
Guy at aamco said its leaking from the top head, I have $2,500 cash and alread have all the 105k parts at home. He said it is hard to get a pic but he will show me. How could this happen? It didn't start leaking until I took my car to the dealer to have them fix a fluid leak from a cross threaded filter bolt. They then told me some transmission pipe was cracked or something, so I told them to fix it. $800 and now it leaks •__•
Just picked the car up. I would upload a picture of where it is leaking but honestly the aamco guy pointed in the general direction but I couldnt necessarily see a whole or anything. He said it appears to be coming from the gap underneath the blue bolt yada yada a tube that runs to the tranny. I told him it wasnt leaking until after I took it to the dealer to have them service it so I did not think it needed to be taken apart or rebuilt. Cost $40 and they didnt tell me anything. They did admire the car though. Has anyone else had a leak like this on the top? I could see oil residue everywhere but couldnt necessarily see where it was coming from without taking the intake and other stuff off.
It's best to clean with brakleen or something similar. Get it clean and dry and look at it again after driving for a while. That's all a mechanic is going to do anyway. I worked at a transmission shop when I was young and unless the leak is immediately obvious as in fluid pouring out, it's easy to misdiagnose without cleaning it up and checking again after its been driven.
Only problem is I am working 4 a.m. to 7 p.m. the next four days, so Ill have to keep an eye on it until I can look at it Tuesday. Might take it up to the nearest dealer an hour away Sunday to have them diagnose it on Monday. Just for safe keepings. Parents want me to trade it in for a gto.. haha I laughed in their face.
How much is it leaking? If you're leaking just a 1/2 quart in 20k miles, I probably wouldn't worry about it. The transmission could die for other reasons.
I also have a case leak and noticed it at 20k miles and brought it into the dealer for an evaluation. They said it was normal and not to worry. I don't have to add ATF in my 20k change cycle and the leak is cosmetic only and behind the 'leak' cover. It looks to be between the case halves like you possibly?
Thanks IHC on the Brakeclean hint- I'll do that next time. I'm not going to sweat it since a rebuild shop could cause more harm than this leak.
My leak looked like this at 38k:

OK, so it could be leaking from the casing, or from some line after the dealer did some work? You need to get a friend who knows cars or a good mechanic to look for the leak after cleaning the wet areas.

FYI OP: Brakleen will damage paint, etc., so you should be real careful applying it.

The only reason the case seals were changed on our Odyssey was because fluid was suddenly dripping on the ground at an uncomfortable rate.

Taking it back to the dealer as the leak is starting to get worse. By worse it isn't progressing but I added three quarts of fluid last week as it was low and it brought it up to the line, now it is leaking fast enough that the transmission is flaring and or shifting sluggishly due to the low fluid so I have to add a quart about every two days. Taking it up to the dealer tomorrow night to have them check it over Monday. Haven't had time to even look at it because of my retarded work schedule.
Good luck bro. I agree with the others--clean the engine completely top to bottom, then you'll be able to find exactly where the leak is coming from.
But a quart every two days isn't a leak--it's a hemorrhage. I've never heard of such a thing. Something is very wrong. I've found that transmission fluid flows very easily with gravity and a leak at the top of your transmission can flow quickly down to make the bottom wet and fool you into thinking it's leaking elsewhere. I had a transmission switch give me conniptions until i found the leak up top. ATF really flows easily.
Are you absolutely sure that the transmission is not overfilled? There is a vent that will purge if overfilled. You're supposed to check the ATF with the engine hot, after turning it off, waiting 60 seconds, and before 90 seconds.
Also check your tranny switch locations (found via search), and your transmission cooler hoses that can easily leak at fittings and hose clips.
Good luck with this bro.

it looks like more of the moisture is at the rear of the trans, hard to tell, but if so its possible it could be the shift shaft seal, or maybe the right side axle seal! and i also agree with having someone cleaning and powder the transmission area to pin point the leak. I think you should take it to a honda/acura dealer because they are more experienced with these vehicles! even though it may look like its coming from the fron of the trans, dirt acts like a sponge and soaks up oil!

Axle seal leaks will usually fling fluid everywhere. A leak that's this fast is probably one of the many pressure areas. It's doubtful this much fluid is leaking out of a bad seal. While it could be the shift shafts, they get hit with a little splash from inside, it's doubtful there would be enough volume to leak this much.
The big question, does it drip all night or only when the engine is running.

Car is at the dealer now. They just called and said they need another hour to diagnose it. That's $220 to tell me what's wrong with it, how do these people sleep at night.
