456GTA trany leak

Very sorry to hear, not had anything like that myself - But how much mileage has it done out of curiousity and has it been used on a track, dont often hear this "real" situation often.

Closest I did was to check the gear oil when car was warm and it was spot on what it should be. Not sure if it applies but did you over fill it at anytime?

Also worth checking in the 456/550/575 Forum there is a thread where someone has posted a couple places in the States where they specialise. On www.eurospares.co.uk there is lot of useful diagrams - The gearbox assembly certainly has a lot of seals - maybe doing the simple checks first - 2nd opinions etc, and replacing seals.

Also does it leak when stationary? Is there a pool under the car when you come and check in the morning?

Worth posting your mileage/year or manufacture etc.

I have posted the M 456 Gear box assembly on here FYI. As you can see it is for me anyways quite a few bits - but if you can locate the leak area it "may" assist in determining the seal or part which is defective - hopefully it is a simple or more cost effective than the figure you quote.

Please keeps us all posted.

kindest regards Aamir

Hmmm... got me thinking I once had a oil leak not an issue when you ran the car all pressure and oil temp etc was good ... but after I parked up there was a small oil deposits under the Oil tank, It seems that I had gone over a road hump and a hairline crack had formed in the tank reservoir. It was quite an expensive part. So the clever guys used some "metal glue" they used on Aircrafts to stick on wings or something this sealed the unit - never had a leak since. Wondering if you have taken a Knock or something?

Again - this is about the second time I have heard this for real - so Pahlease do not shoot yourself.

kind regards Aamir.

 

You are told you need a new transmission because of an oil leak!! Farrrrkk off!!!

It can only be a seal and I am sure it can be fixed. If they reckon they cannot get seals for it, then I call BS. Ferrari has seals made for them. They do not make their own seals in-house. Possibly be SKF seals me thinks.

You need your mechanic to pin-point the oil leak, pull it apart, then see which seal is leaking and get the part number off it.
If there is no part number available, then take the seal into a parts shop that specialises in seals and match one up.

 

I think that the ominous 456 transmission has been mentioned before. Apparently Ferrari considers it a NON serviceable item! And they don't offer any internal parts.... I remember posting a thread about one that I saw on E-bay a few years back. That's when I learned that they were basically UNrepairable. Sounds like a Ferrari racket to me.

 

Surely it can be pulled apart and seals replaced?? Thats all we need here. Id be more worried if the transmission was worn/slipping. I doubt there would be something similar out there to exchange parts with.

But a dirty old leaking seal can be replaced. I hope.......

 

Totally agree with Pap on that one and with the amount of posts he has I don't think Ferrari should even consider qustioning his judgement

It would be a sad situation if that renders the Sale of the 456 careful owner low mileage just" needing cost new gearbox. If I knew that this was the only thing wrong with it and I had cash to burn - this would be a great Buy I would start with taking off all the seals and rubber off my wifes utensils and pressures cookers in the first instance .

Joking aside - the 456Junkie indicates that the Mechanic has already done a seal, i'd say do it again pretty please.

No offence - Any pics of the car and said Oil Leak? some are getting sceptical of the post.

kindest regards Aamir.

 

Thats what I would do.

 

Sorry to hear about the leak.
My question is why did you have the seal replaced the first time? Was it for a leak? Since it seems that parts aren't available, did your mechanic
'make ' a seal fit? I remember seeing other posts that have named the manufacturer of the box. Was it GM?

 

good luck

 

i remember reading something on the 456 auto trans, it was made by a company in America i think, it was designed similar to a standard american common box, sorry i dont remember the detials, but this whole topic has been covered before, might be in the 456 forums
EDIT: heres the topic you should read
http://www.ferrarichat.com/forum/showthread.php?t=118551

 

Would it make more sense for this interesting thread to be under the 456 section where there might be more expertise and more other 456 owners who will benefit from the experience?

 

Metal Glue - around the seal ....Hmm I am not sure if that will work - the area where it was used was in my instance was a hairline crack in a metal assembly. time try all things e.g. fabricate or get a hold of a bigger "fatter" Seal - see if the holds the oil in.

Really sad to hear that this is still an issue. Again, ref overfilling etc. any issues there?

 

If he replaced the seal once, do it again.

A seal is a seal. There are thousands of them out there. Pull it apart again, remove the seal and get one matched up at your local seal shop (SKF?) and throw it back in there.

 

If the transmission is working fine, but is leaking some oil, then whomever is suggesting you to replace the transmission is giving you plain BS and is trying to take you for a ride.
If the leak is from the same spot as before, then your mechanic did not do a proper job the first time and unless he offers you to do it over again at no extra cost to you, it may be a good idea to go somewhere else.
There is nothing magic or arcane about an automatic transmission and much less it is "sealed and non serviceable".
As the saying goes "if there is a will there is a way" and you need to find an independent that is willing to use his brain to fix your leak.
It may be more than a seal or a gasket (i.e. the seat may be dirty or the surfaces may be slightly damaged) but it cannot be impossible to fix, but please do not use metal glue or anything like that.

 

it's just a seal, and in most cases you will just need to re-torque it.
when replacing the seal, was it torqued per spec?
who told u 22K for a new tranny because of fluid leak? crazy.

 

I don''t know who your mechanic is. However, if you are in the orange county area, you might want to get in touch with Joe at Concourse Automotive in La Mirada or La Habra. I can't remember the city. He seems quite knowledgeable and helpful.

Good Luck

 

I always thought it was more of the fact that it's an automatic.
