what's the gear?

Hello Audrius, at first, I wellcome you to this brilliantly forum.

But please describe your problem more exactly.

When do you feel the "fifth" gear? What show the transmission lights in the KI?

Hello Audrius;

do you feel this switching operation at a speed of approximately 80km/h? And simultaneously to this, the engine speed is falling about some 100 rotations per minute?
Then, the solution is as easy as tranquilizing: It is the "torque converter transmission", which is activated by the transmission control unit. If this has happened and you continue accelerating, the engine speed should rise almost straight proportional to your real speed, because there is no longer any "slip" inside the gearbox.

This is also described in the "Technik"-Category of this Homepage; there is a chapter where you can find a lot of information about the gearbox.
Just follow this hyperlink: http://www.audiv8.com/german/technology.html

So don't worry, there is nothing wrong with your gearbox

Hope this helps

Alex

Thank you wery much for information!
Now it's clear. I feel a good spirit of this forum!!
I'm not so good in english - especially technical language. But I'll try. :)

Hi everyone, in my car this I feel at 95 km/h. I thought it also 5th gear It would be very nice that technical data about gear box could be in english. But here I can't find anything in english, only this forum.
