This then brings up the question of what fluid to use as if you were flushing with the genuine ZF stuff the cost would be 2012 TDV8 Vogue (L322) |

You can bet he's not using ZF transmission fluid. |

I think Bodsy uses Febi Bilstein fluid.

That's pretty much what I did - the 4th change was ZF Lifeguard6 with an added squirt of Shell anti-foaming additive. The S&A gave immediate improvements - unsurprising as the original oil was still in the transmission after 150k.

Can't say I noticed any 'immediate improvement' with either fluid change. My first, second and third seem fussy sometimes so I'm hoping the gearbox will adapt itself with the new fluid over the next few months. Only done 10 miles so far. |

They are very fussy on quantity - check the level 'on the level' and within the fairly restricted temperature range. I found mine needed another 0.35l - not a massive amount but it did get rid of some of the initial harsh changes, driving it for 50 miles unbroken in mixed traffic really helped too. |

Can reset some of the adaptions yourself for some of the ZF boxes: (IIRC) Ignition off Press accelerator to the floor. Ignition on Hold for 30 seconds ( I wait a minute ) Ignition off Foot off accelerator. I think it should re-learn fairly quickly after that, but I think the following is the process (or close to it ) to give the best results for learning adaptions - I remember reading it somewhere a long time ago, and did/do use it. From standstill accelerate gently - 1500 to 1750 rpm but no more than 2000rpm - up through the gears into at least 4th and maintain 50mph for a short period ( i think it might be as short as 10 seconds ) The lift foot completely off accelerator Let the car decelerate of its own accord and let it drop down through the gears Once your down to a slow speed ( cant quite remember what, but lets say sub 10mph) gently brake to a stop, or repeat the acceleration again Now I think it’s in the region of about 5x times of doing that process and the box will re adapt its shift changes. I’ve even found that in during average driving, I’ll do this method fairly regularly as my shift patterns mean I drive home at night, so I can do the deceleration thing on approaches to roundabouts etc when there is no other traffic. V8 or else ... Last edited by fisha on 31st Jan 2023 11:36pm. Edited 1 time in total |

It's always good NOT to feel any difference from any form of gearbox service... Be it a service or a flush... If the gearbox improves then its already damaged im afraid |

That's quite reassuring Craig. I've read of people saying there was a vast improvement of smoothness after a fluid change so I'm open minded on that one. Does it last?
