    Default Torque converter question

    Hey guys,

    When the torque converter is mounted to the transmission and you turn it by hand, should the output shaft of the trans turn too - assuming that it is "in gear"?? I'm a little confused about how that works.

    Thanks!

    No, it won't. Auto trans will need hydro. pressure to work, or it just free wheels.

    Thanks for the reply

    One other question...
    What happens if the torque converter is installed empty?
    It lost most of the fluid while trying to get it mated to the trans...

    Will letting it idle for a few "prime it" ??

    if the converter does not have enough fluid it does not transmit rotation to the transmission. No hydraulic pressure = no rotation - see just above...

    Well, I understand that, but I'm wondering if it will get primed from the oil in the pan...

    Default Yes the oil pump will fill up the torque converter

    Oh thank goodness. Some were telling me that it won't get filled and I was getting worried!!

    whew. Thanks.

    BTW - what is the point of even adding fluid to the converter before installation, then?

    Default It just speeds the process if you fill it up partially when the torque converter is

    out of the car. Most mercedes still have a drain plug on the converter itself and when you change the fluid you're supposed to remove the converter plug and drain the converter completely

    Awesome.
    Now I can sleep. Thank you.

    This whole process really worries me, there are so many "be careful" things about the torque converter. Maybe I'm just going .

    I'm worried that its not going to fill (well.. not anymore) and that its not seated properly - but it went in pretty damn far and bolts up properly, so hopefully that is ok.

    Is there any specific way to know for sure that it is seated correctly aside from feeling the 3 "clicks" as it goes in?

    Edit: Clutches are so much easier!

    Default If you didn't have to force the transmission housing together with the

    motor and if once the bell housing was bolted to the motor you then had to slide the torque converter forward or rotate it to line up the bolts then its engaged properly.
