Gearbox dead.......again

13 posts in this topic

So after just 16k miles my box has shot itself! Can't even put it down to hard driving, I drive like an old woman! ETA motorsport gave me the bad news yesterday after I asked them to investigate a constant whining noise from underneath. 

Will keep you posted on the outcome. 

 

How bad are these cars!

After 16k miles? Have you had it rebuilt already? I take it your car hasn't done just 16k in total....?

 

Edit: just read your title - 'gearbox dead, again'.

I would suspect the problem is with whoever rebuilt the 'box mate. These ZF 'boxes are quality units. With an oil change every 60k they should last forever

Sorry mate, no. It was done at 128k and now has 144k. Can't think what the noise would be as it continues in park. Am I right in thinking the only moving parts are the torque converter and oil pump when in park? Either way, it was all replaced/reconditioned 16k ago.

When in park there will be still some bits of clutch drums and epicyclic gears turning but they will not be transmitting any torque as no gear is engaged.  So yes there will be bits spinning that can cause a whine when in park.

 

My 6HP26 box failed at 91,500 miles despite being serviced twice, Eclutch let go quite spectacularly on the M74. The fix was to rebuild the box, cost to fix = ~ trade in value of car, hence why I know own an F10.

My eclutch was the reason it was rebuilt 2 years ago. This is the main reason I kept the car just to get my money's worth from the box build, however, I'm regretting this massively now. Hands down, worst car I've ever owned. It's been a long 3 years.

Depressing to say the least. I guess you're out of any period of warranty on the rebuild? I don't know which models were fitted with the 6HP26 gearbox and which had the 6HP19 but it would be interesting to know the differences and which has the higher rate if failure. My 525d has the 6HP19 and is booked for oil change in May.

A rebuilt box is essentially new internals in your old casing, so in essence its a new box.  All the important stuff is new, ok so the actual gears may be original if ok but all the seals, friction materials, bearings (the stuff that wears out) etc will be new.  A rebuilt box should not have failed so soon, points to not being re-built properly. Or you are running a massive supercharger and the torque has mashed the box/

 

The 6HP26 box is is in 530i/d upwards I think.  The 6HP19 has a lower design torque input than the ...26 box but perhaps if it actually uses the same parts inside it will be more reliable in service as it doesn't need to handle the increase in torque even though it may be capable?

What year is your 525d?

I thought e60 525d's had the 6hp26 units.

Reaoloem say @pidgeonpost E60 is 6HP19, but lists 6HP26 as also available on that engine if you don't enter a chassis number and just select one at random

 

Actual chassis number is best way to confirm of course.

The weakest point and the most neglected aspect of the repair is the mechatronics valve body which controls fluid pressure via solenoids.

Yes, fed my VIN into realoem and it reckons it's a 6HP19. The car's March 2007, early LCI.

For the 525d when they switched to LCi they swapped the 26 box for a 19Z, engine went to the M57N2, if your close to Nottingham I don't mind taking a look

Thanks for your kind offer, but it's a bit of a trek for me. Now almost certain it's the HP19 fitted.
