    Ok people small update.
    I asked why the TC needs to be replaced: the answer was that the clutch is slipping and small particles will fall in the oil. Possibly contaminating the rest of the system. Making it most possible that a costly rebuild could be due. ..

    But now I wonder: the torque converter is a sealed unit isn't it? And as far as I can see it is situated in the front section of the transmission. Does is come in contact with tranny oil? And could it affect the tranny? Or is it a piece on its own in the bellhousing of the transmission.

    Any advice is appreciated.

    The TC is full of oil and it circulates throughout the transmission via the pump. All the oil should also be going through the filter.

    Aha i thought it was a precharged unit. So it could foul the unit?

    I guess that would depend on what the debris was and whether or not the filter and drain plug magnet would capture it.
    Next, the 'clutch' is a solenoid in the valve body that increases the pressure in the TC to eliminate most of the built in slippage. If it isn't fully engaging, it's easy to replace the O-rings on the solenoid. Also, a full fluid flush will usually cure the problem because the new fluid detergents aren't worn out yet. Were it me, I'd do that first.

    Ok glake thank you. I think it would be benificiary that I get my hands on a manual or drawing of the transmission. Do you know the type of tranny?
    You see we dont have much experience with automatic transmissions in Holland. I think you are perfectly right in going for the simple fixes first.
    Many thanks so far

    Bu chance does anybody have a manual which I could purchase??

    Hi guys,


    Small update on the transmission shudder: well it is finally gone!
    Now I have done two things:
    1) a complete cleaning of the system under load ( a german system: flushing the system when a cleaning device is connected and the car lifted from the floor. Subsequently the mechanic drives the car through all the gears and takes about a hour. )

    It solved nearly 50% of the problems so it was not the ultimate fix..

    2) the car was in desperate need of service which unfortunately cost me an arm and a leg but did solve the transmission problem by uploading new software.
    I failed to ask what update is was but can check. It did the trick and driving (again) in the mountains proves wonderfull.

    Hope this lasts !

    You can get all sorts of parts, including rotors from www.rockauto.com and they ship overseas. Good prices too.
