    O-ring torque converter

    Hi there! First post...so here we go.. My '54 is leaking from the TC so I removed inspection plate and cover. The TC is perfectly dry (outside) from the near of the front and rearwards, but wet where I guess the O-ring will be.
    I plan to remove the 322 to have this adressed but I'd like to know if I could get by by just replacing the O-ring or should I replace the front seal on the tranny as well? ( Leaves are fallin' and I have to work on the car outdoors...)

    If the seal isn't leaking you could get by without changing it. Of course it might start leaking 2 weeks after you put it all back together. Or it could be the seal that's leaking now. Might as well do it right and replace the seal. I assume you made sure a drain plug isn't leaking..........Bob

    Re: O-ring torque converter

    When doing this repair take your time and follow the service manual.


    These converters have weights on them and you want to make sure you assemble it the way it came apart.


    If it is like my 55 you should only need to remove 3 or 4 bolts to seperate the converter from the engine flywheel. Don't make the mistake of removing them all before you have everything marked clearly.


    Good luck,

    Re: O-ring torque converter

    You go that far, putting in the o-ring, then do the front seal too. Rule of thumb: whenever you have the transmission out of the car change the front seal (and rear main seal on engine). Then you are good to go for a long time.

    There's a few of us here from the Commonwealth who haven't gotten lazy and started leaving letters out of words like neighbourhood

    I'd love to hear more about that Super, perhaps even a few photos. There's also a site at 1954 BUICK | The Forum & The Website that you may want to consider visiting.

    Your English is a Hell of lot better than our Swedish. Come to think of it, it's also better than in a lot of the posts from the U.S. Good luck with the dynaflow. It's actually a pretty easy trans to work on. BTW, do expect your trans to drip some amount of fluid no matter what you do. It's just it's nature...........Bob

    Re: O-ring torque converter

    Have you checked to make sure that all the bolts holding the front cover of the converter on are torqued to 25 ft./lbs? I had a few loose ones that caused a massive leak...tightening them turned it into a manageable drip...just right for a Dynaflow.
