Gearbox fault?

Recommended Posts

So had my 2006 e61 525d for 2 days. Everything seemed fine till. Was coming through town and box didn’t want to engage then suddenly would work. Then it cleared itself and has been fine. 

Many ideas?  Service maybe sort it out?

I would have it serviced - my gearbox died on me last year completely, got a gearbox service done first to see if cheaper option would help, by doing that an £11 pound plastic part was found cracked to be the culprit.... long story short was replaced and car was working fine after.

 

I wouldn’t call the gearbox service I did a waste of money as even though BMW says its lifetime.... it ain’t and also the actual culprit wouldn’t have been found without doing it, so had to be done either way.

I got the software and got codes checked, was showing up as a couple of the clutch packs gone.

 

And as Steve has said - must be reason why was sold, one of my options was to get a recon gearbox fitted then sell of the car ASAP when my box packed up.

 

But a professional gearbox service which costs £300-500 depending on where you go and MAKE  sure the right parts are used original BMW even down to the oil!

My box has been a constant concern of mine,sometimes feels fine but sometimes,usually when cold it always feels like the clutch is slipping. (Auto535)

had the box serviced aswell as a few other bits n bobs,seemed better for a short while but ultimately it’s just not as impressive as I think it should be.ive driven 2.0tdi that feel so much torque filled which they should not compare...solution could be one of a million things...

ZF suggest no more than 70k between services on the auto box, my car came with 103k and is booked in with a local specialist Wednesday as a preventative measure.

Yes, I bought mine 4 years ago at 104k miles and immediately had the gearbox serviced. It was just as well, as there was a leak from the plastic sump. Now 140k and all seems fine, touch wood. I need it to last another two and a half years which is about when I'll sell or scrap it, so fingers crossed there too !

Thats why I don't own an E60 anymore, Eclutch showing up as a fault code. Quoted trade in value to refurb the box as the cure. Certainly not an £11 part!

 

To the OP, was there any error message showing on the dash?

 

A service will be no bad thing as they might see something obvious. A service should read the fault codes and look to see if there's a software update for it.

Because of the mechatronic sleeve being cracked, which was the £11 plastic part, it threw up the clutch pack errors which obviously made me cak my pants.

 

After being fixed and errors cleared, never came up again.

 

But I agree about E60 ownership - loved it the first couple of years (prob as I had 2 years BMW warranty) and after that, when things went wrong they came in quick succession.

 

The whole DPF thing is mare along with the temps... let’s not go there!!!

Mechatronic sleeve was replaced on mine, 500 miles before it completely failed so it wasn't that in my case.

 

My bridge seals were not replaced, which is another weak point, but it could be anything from worn bushes to worn clutches...... hence the need for a thorough checking.

That sounds a lot like a worn torque converter lockup clutch. If you get it fixed the car will feel a lot better. 

 

When the engine is cold and also below 30mph the car will behave like an auto with a viscous coupling of engine to wheels. With a working TC clutch above 30mph and with a slightly warm engine the wheels should feel directly connected to the engine bar the odd gear change.

Specialist said if the service didn’t cure it was probably TQ...so I’m now 99.9% sure it’s that..Sussex’s autos do upgraded TQ for £200..they either send off the shelf or refurb...I’ll definitely be ordering soon...I’m assuming when you say TQ clutch you mean the actual TQ ??

The torque converter contains the lock-up clutch. It's the lock-up clutch that has the problem. The fix is a rebuilt or new torque converter.

 

Failed TC is really common on 535d's.

 

Mine is a rebuilt one from Sussex Autos that I fitted myself. I highly recommend Sussex Autos - the rebuild quality was incredible.

What were your symptoms....I’ve got no rev fluctuations or jittering at all,box is silky smooth but and it’s a big but,there’s like a big flat spot,it’s nearly always there and has been for the last 6years of ownership. At day 70mph if I accelerate there little linear pull it’s like a flat spot then gear drops and away...as I said earlier,I’ve owned 2.0tdis that felt so much nicer in general,not as quick obviously,justdoesnt feel effortless as a diesel should

Ah that does not sound like the TC. That sounds like a vacuum leak, a stuck bypass valve or a faulty pressure converter.

 

Vacuum leak extremely likely or even a blockage.

Faulty pressure converter pretty likely.

All vac hoses changed recently for oem..

funny enough,it went to a local garage first with a power loss issue and that guy send one of the actuators was very stiff..who knows,I need a bmw genius to figure it out..

Hello, I am resurrecting last year's thread just to say a few things...

There is no such a thing a ''lifetime oil'' It more or less works like this: You buy a brand new car and as long as you are the owner of the vehicle, it is still under ''lifetime oil'' warranty. As soon as you sell a car, it is expired. ZF has updated information and now BMW say's the same thing. Its 100'000km/62'000 miles instead of ''lifetime oil''

Source: bavauto 

Some other interesting read as HP6 gearbox is used not just in BMWs ZF6HP info

 

Regarding a gearbox issues, I tried to reset the gearbox adaptations and it worked wonders !  I had a problem when I was at the traffic lights and I have to stop, whenever I pressed on the accelerator to start moving off nothing happened for about a second or two.  Rpms went to around 1.5k and only then(most of the times) I took off with a slight kick(when TC engaged).

After I reset the adaptations, it was smooth straight away. No more ''lag'' from standstill and while cruising on a motorway instant mpg needle showed a bit less consumption. Definitely cured the problem. My car has done slightly over 200k miles. 3 litre diesel. I reset the adaptations with ISTA.

That’s a lot like mine,also at 70mph as an example if I gently accelerate I can see and here the revs raise the mpg gauge drop but doesn’t move away as should,until it feels like it’s dropped a gear and away
