Hi, I have recently experienced the gearbox reluctance in changing up from first to second gear. The engine revs mount to 4k approx - the car continues in first. I remove foot immediately and second is then engaged. This occurs intermittently - when pulling away from the lights for example.

I had changed the XF fluid, gearbox sump and filter back in 2020 at 78k miles. The car has covered 101k miles to date. Any advice or diagnosis from memebers would be most welcome. Thank you Dominic

Is it in Sport mode?

Hi Mike,

 

No i checked that - my first thought. I have been out this morning in it - Iput it in 2nd and then moved it slowly between all gears before moving off. It seems fine now !!

 

Thank you for your thought, I appreciate it.

 

Have a good day

Fairly cheap to get a new set of solenoids and get them fitted.  If you have good access you could do it yourself.  One other thing, there is a multicore cable connecting to the GB.  Clean the connectors.

You could probably do a complete fluid change ataa competent garage too. This GB is vrtually bulletproof..... There are many threads on this box, check on the BMW site for more info.

Hi Mike,

 

Many thanks for that - very reassuring to understand it is a terrific GB. I shall look at replacing solenoids and cleaning the multi cable connectors.

Thanks again

Dominic
