    Default Puke Tanks for transmissions

    Anyone had any experience with these? Are they a worth wild exercise.

    Im running a t400.

    TIA

    Better than spewing oil under the rear tyres.

    The ones that bolt onto the pan rail don't hold much and have a breather off the top.
    People don't seem to check or drain them very much, they will fill and overflow quite easily.

    I generally ask guys to run them to a decent sized catch can or the engine catch can.

    You've got a 400, pretty unusual to lose oil out of the breather with them.

    Haha. Was hoping you would see this without me having to harass you.

    Yeah I would of run it to a catch can in the bay. On the theory it drains back into the sump once the car is off and cooled down. If it EVER overflowed.

    Stumbled upon then and thought this idea would of saved me spraying oil a few times.

    The trans specific ones don't drain back to trans sump that I have seen.
    The ATI and TSI ones I am familiar with just bolt on and have a little wing nut drain plug and a breather on top.
    If they fill up, they'll still potentially put oil under the car.

    I have an alloy governor cover I make that is tapped out for a return feed if you want to go that way.
    I use these normally for external converter pressure regulators and converter pressure dump valves but could easily be incorporated into a catch can return.

    The boys have almost finished a VK for drag challenge with a similar combo to you, made around 600 at the tyres.

    This was the one I was looking at. It has a drain point also.

    I assume the inlet to the tank doubles as the return back. For when the box cools down.



    I seen that VK. It makes me sick to think mines still an empty bay.

    Not sure which one your looking at, can you post up a link.
    The inlet to the tank is normally just that, there is no negative pressure in the trans to draw fluid back as it cools like a radiator recovery system.

    I hope the inlet is at the top near the filter or it will restrict the trans from breathing.
    Looks like it could be a good thing though.

    When I get engine and box in I might give you a buzz and pick your brain some more.

    Hmm yes interesting... Perhaps the line up to it should have a tee fitting just prior to the tank? One line to the bottom for the drain and one to top to breathe?
