530i gearbox issue

Recommended Posts

Just returned home from picking up a 530i sport touring, the car drove fine initially, but when I stopped at the services on the way home I tried to reverse and the auto box will select reverse, but it just revs freely and only just creeps backwards, but would definitely not pull itself up a hill.

I've come home from a 9 hour round trip and read a few threads where the general consensus seems to be that the gearbox is gone, but I'm interested to hear if anyone has had these symptoms and the box hasn't been knackered? Is there anything else that can cause this, or any other fixes?

I really like the car in every other way, it's had lots of preventative mantenance done, the seller was as genuine as they come, is still answering the phone and has never had this happen before.

But obviously, I'm a bit concerned. Any help advice appreciated!

Mine wouldn't reverse out the drive, it was like the handbrake was stuck on.

Have you driven it since?

After this mine started going into trans failsafe and was a rebuild job.

Haven't driven it yet this morning, was going to try and get a lie in. But as soon as I woke up I'm thinking about it!

I'm going to try it again shortly, and take a video to send to the seller. Just to prove I'm not having him on.

It goes into reverse, but the engine doesn't seem to engage the box. The first time it happened I thought I'd accidentally put it in neutral rather than reverse because the engine revs freely, but the car doesn't move. Then on the flat, it just about creeps backwards, but the speed it moves bears no correlation to how high the revs go, and I doubt very much if it would pull itself up any kind of gradient. Luckily, where I was it was completely flat. If I'd have parker nose into a downhill space I don't think it would have moved.

Hmmm.... Starting to fear the worst

Give it a try today.

If the box needs rebuilding it'll probably give a big clunk and engage trans fail safe mode and give you 3rd gear as drive. That's what mine did.

Clearly you have a big issue on your hands if the gearbox needs a rebuild £1000-£2000, I would be contacting the seller to work something out, I'm not sure what your rights will be if it was a private sale, was the car describe's as in good condition, if you bought it from a garage then get them to fix it.

Private sale, but there were no gearbox issues described in the advert, and the seller said he has not had this issue previously. I'm inclined to believe him as he seemed genuine.

I'm going to go out and try it now.

I would say your going to need a gearbox rebuild, I think you will find out how genuine the chap is once you ask him to pay £1500 to have it repaired, because in his rights he does not have to do anything. I fear the worst hear but I hope you can work something out with him.

Unfortunately this cracked reverse drum issue is quite typical on these ZF 5HP19 boxes. Sounds like very bad luck if the reverse was working when you bought it.

Nope, still not working. No clunk, or noises, and forward gears are fine. Just no reverse.

Anyone got a box for sale?

Don't think it's worth putting a recon box in. Just a straight swap with a used box would be the way to go.

This happened less than 50 miles from picking it up. First service station on the motorway, all it had done was 60mph on a busy bit of M5 Friday 5pm hence the 9hr round trip.

Not bad value if your torque converter is ok -

It may be worth asking an auto specialist for a repair quote as it might not be much more than a used box plus fitting labour, and you'll get a guarantee of some sort.

If the gearbox had failed a week or a month after you had bought the car then that would be bad luck, it sounds to me as though the fault was inherrent at the point of sale, did you check reverse on the test drive? how long did the seller own the car, write a letter to the seller keep it pleasant and you may be able to work something out together.

If you are stuck with the car, maybe do a little trouble shooting before you buy a new box? Firstly, do you get any indication in the dash when you engage reverse and rev it? I'd expect you to get a gear symbol, trans program or whatever the E39 shows when you get a transmission fault. Secondly, check the shift cable is actually adjusted and moving correctly. And that the shaft it rotates is moving. After that it is drain the ATF and drop the pan time. Inspect the pan. If you find nasty sharp bits nowhere near the magnets, the D/G drum has probably blown. But check your manual shift valve. If that has broken, you could get the same symptoms. I'd say if you are good enough with the spanners to take the gearbox out, you might want to consider changing the drum yourself if that has gone. IMHO, the cause for the drum failing is a pressure issue but you can get a modified (stronger) drum. These might help if you decide to go down that road:

I hardly did a test drive as I'd spent 5hrs in the pissing rain getting there u just wanted to get home. But I did need to reverse it to pull away from his house, so it did work then. But 45mins later it had gone.

That's another reason I'm inclined to believe him, as far as I can see once they're gone, they're gone. There isn't a temporary fix is there?

I must have given the wrong impression, I'm definately not handy enough with the spanners to be taking a gearbox out. Also my misses is about to drop any time soon, she's due in the 18th of August, but we're expecting her a couple of weeks early, as that seems to be the norm in her family.

Hence buying the estate, didn't want the misses having to put the push chair in the back of a saloon.

I'm waiting for a callback from my Dads mate. He might be able to get a recon done for a reasonable price.

You may well be right in assuming that the gearbox is stuffed. But do go slowly. A shift valve is about a tenner, a recon box is about a grand. Get some expert help. Sounds like you have more important things to think about
