Went on a Auto Gearbox course recently, without getting too involved in all the gory details, I'd just like to share this VITAL piece of information with you all  You know when the customers arrive back at reception and say, SINCE YOU DID XXXX  my car is now doing XXXX and you think FFS here we go.... Well actually that customer statement can now actually be very true in some instances and you the mechanics will not even know you f*cked the box up  How it happens; The customer asks you to change the gear oil, you ask the parts department who tell you that the oil is part of a service kit  you think, service kit ? You are provided with a new sump for the gearbox, yes a new sump, plus some filters etc. You remove the old sump and naturally you take a rag and wipe off any surplus oil residue around the gearbox components and mating faces. Yes we do that don't we ? Not any more, be very careful. If you accidentally or otherwise touch any part of the internals of the gearbox that house any electrical components you WILL cause electric static from your hands to fry the gearbox components, yes I sh1t you not, this is a very real issue. The customer will return to you approximately 2 weeks after your service on a recovery truck complaining the gearbox has failed, your then into a sh1t load of money to sort the problem out. This is NOT A WINDUP guys, proceed with caution if you do any service work on auto transmissions. |

Static discharge is well known in IT circles, however if it was a problem then the only way to avoid it totally would be to earth the car while working on it and earth yourself too. Can't say I've ever heard of doing either in a mechanical workshop.

We had a recall on mk4 mondeo interior alarm module recall Danger of static electric from body harming new module on installing New module came with a earthed ribbon to attach to your self and a ground point on vehicle |

I was going to ask how you could do anything in the engine bay of a car without touching something metal, then I remembered the lashings of plastic most cars less then 20 years old have over the engine bay...

The question has go to be, what sort of OEM produces gearboxes that cannot take the normal "knocks and bumps" of an automotive environment, like servicing and repair? I think that they need to go back to the drawing-board....  |

Im sorry, but I don't really buy it. What component gets damaged? What gearbox are you talking about?
Gearbox oil services often gets neglected, and then get done at the first sign of a problem...

Why does the damage from the static take 2 weeks to manifest itself?

I wouldn't buy the damn things either we are talking about the internal electronics components, which my opinion thinks they must be badly designed to allow this to happen. I think I am referring to the next generation of transmissions by ZF, so many people may not have come across these transmissions to date, I am also told they are very reliable, I suppose until we touch them Why does the damage from the static take 2 weeks to manifest itself? I don't know the answer to this, but hang on in there I'll ask the manufacturer. I didn't think to ask  |

The cynic in me will counter this by all the vehicles exploding as you use a mobile phone while refueling and airbag's exploding by not being earthed and the courses I have been on saying 1 single missfire will destroy the cat, as Old Joe the car cleaner goes by on 2 cylinders after steamcleaning the engine bay.
