    I have an eaton 778 transaxle that I had to replace the lip seal on. It doesn't turn as fast as it did before the seal replacement. I think there is air trapped in the system. Is there a recommended procedure for bleeding the air out of the transmission?

    Here is a paste from another thread;


    Purge any air out of the system by jacking the drive wheels off the ground and block the unit. With the throttle set around 3/4 position slowly move the controls forward to reverse 8/10 times then test drive the unit.

    I guess I'll have to just run it some more. I did this last night after filling the case. I was thinking there was a plug to take out that would allow air to bleed out of the system. It looks like air would have a difficult time making it out through the fill hose.

    Nope, No plug. Just make sure you go full travel and pause a few seconds in each direction.
