Gearbox failure

Recommended Posts

Getting fault codes 4f81 and 4f82 as well as the 'transmission fault' appearing on iDrive. Took it to a local indi who thinks a recon is the way forward at £3k. The car has done 142k on what I presume is the original gearbox and without any apparent ATF changes. I've had it for the last 3000 miles.

Are there any transmission specialists in the Berkshire area (I'm in Newbury) that I should be talking to next?
Is recon the only sensible thing to do at this mileage?

Any other options I should consider?

cheers
Chris

Cripes. Is the box changing gear normally? Do you have an autobox specialist nearby for a second opinion? Maybe a gearbox service would sort it unless it's obviously something dire mechanically. £300-£450 sounds a lot more attractive than £3k.

Check this long thread I started last year when my gearbox packed up with similar codes. Luckily my problem ended up being a cracked plastic part only costing £11 but it took a gearbox service to find the issue out.

It's changing normally but slipping on 2>3. I've had a recommendation from ZF themselves to give 3dtransmissions in Reading a call, which I did and they do reconditioning in-house so I think I'll take it there. Thankfully I don't have the LCI so no danger of slipping into park (that sounded highly inconvenient!).

If only slipping - a gearbox service could and should do the trick just make sure you use ZF parts and oils.

Interestingly, it wasn't slipping until it came back from the local indy today (who advised that the fluid level was overfilled and they reduced it (at the right temperature)). But the fault codes came up before that, so perhaps it was slipping but it wasn't enough for me to notice it.

£3k is about right for a full recon box......which is why I don't have my E60 anymore. Mine went into limp mode due to E clutch fault 4f95 IIRC.  Recommended course of action by transmission specialist was a recon box at give or take the trade in value of the car @91.5k.  Your fault codes relate to Clutch A and Clutch B ratio monitoring which certainly sounds why it would be slipping.

 

Take it to the specialist and see what they say.

It's back from 3D Transmissions. A full recon was recommended and it's now back working again. After a 45 minute drive, it seems happy and the occasional 2>3 hard shift appears to have gone.

So you got a full reconditioned box then?

 

Bearing in mind a recon box is essentially new inside your existing casing. It should outlive the rest of the car.

 

Can I ask how much if you don't mind?

Yep, full recon'd box, which they did in-house. Just shy of £2300 all in. They recommend annual fluid changes, which in itself seems excessive but if I do that annual change (£230 or so), they'll re-warrant the entire box for a further 12 months and they'll do that in total two times, giving me three years warranty in all. And its transferable, should I sell the car.

That is a really good price. What about the torque converter ? Was that OK ?

Having same sort of issue jumps out of gear and stays locked in 1 gear switching off and on cures fault I will get oil and battery Checked. Have heard online can be the lower crank sensor. 

Glad yours is sorted I hope mine's bit cheaper :mellow:

They would have told you if they were replacing the TC too.  

 

I was quoted £2,600 and £3,200 for a full recon (inc TC) from two specialists for my 6HP26 box when I got clutch failure, so it went for the F10.

 

Going on my prices and what you paid for it is a very good price as others have said, or they didn't replace your TC.
