[discussion] Zf6 hp26 gear change issue
#1
Hii guys!

Got a 2010 bmw 330d that’s been giving an occasional kick when changed from 2nd to 3rd often happens when driven whilst still cold or at high temperatures.

Read up that some guys recommended trying out a oil change however when the car when it for oil change the mechanic said that the entire mechatronics should be replaced.

Could you guys please share your suggestions?

Take it to ZF in Germiston and get a proper evaluation and quote.

I did and they quoted a whooping R40K

Did they give you a report? Printed paper with line pressures etc.

Sounds like they are quoting to replace.

It doesn't seem you are valuing the opinion of the very guys that built these gearboxes?

What exactly is your question?

unfortunately, in most cases, by the time you start feeling issues with the ZF gearbox, its already too late. May i ask what is the mileage on your vehicle and if the gearbox was serviced.

These technology in these gearboxes are way ahead of its time and it was designed to adapt to the wear over time. The problem is when the wear has gone too far and now the dirty oil is replaced with clean oil.

Usually the check parameters first prior to changing oil. If outside the parameters they wouldn't change to new oil. There should also be a option of reconditioning a mechatronics. But lets see the info they gave you

That box is out of spec. Hence why they quoted the price they did

From a financial perspective it may be more feasible to upgrade to car to a newer model. I also have the same issue on my e92, weirdly enough the guys at Tune Tech still suggest that the oil be replaced. I've opted to follow ZF's advise however, and will just refurbish or replace once the gearbox fails.

so, instead of spending R40k to fix a gearbox one should spend R400k on a upgrade? Can you please elaborate how an upgrade is financially more feasible?

Please elaborate on where I advocated spending 400k on an upgrade?

Well you used the word upgrade, he currently drives a E90 330d and a F30 varient will be in the region of R400k

Or did you mean he must "upgrade" to a Yaris?

Or it could mean he upgrades to a 2011/2012 model E90 330d with a gearbox that is in spec and can be serviced.

Even if one can find another E90 330d "within spec" it still leaves you with 3 issues :

1. The R40 000 or less hypothetical budget to sell the old car and find a replacement is extremely thin.

2. Selling a car where you are aware of all the known issues vs a potential money pit. Better the devil you know.

3. So now you sell your old car to some unsuspecting fool, then he is stuck with the problem?

Unless I am missing something there is no way its a better option financially to sell the car AND upgrade.

I had 6hp issues and ZF quoted me in the same region.

I did an adaptation reset and the full procedure and the gearbox did get much better, in the sense that I never experienced the issue again. Hope it stays that way!

My issue: Under hard acceleration when shifting from 4 to 5, it would give a loud thud and sometimes not go into 5th. If i left the throttle as it shifted, it would go into gear and then I could floor it again. No slip once it engaged 5th. Also from 6th to 5th under hard acceleration, it was all good.

The other option is to visit the ZF guy in Pretoria. Apparently he is quite good as he worked for ZF. When I called him some time back he said its like 10k for an exchange box without oil.


@rash also knows this dude.


Not sure if I can post his number?

Would be good to get more info on this, exactly what is involved and exactly what was done to the box that you get back.
