    well to add to this mystery, my dads pontiac parisienne that sits spit out all of its tranny fluid for no reason one day.. he filled it back up and hasnt leaked since..

    I know of a few people this has happened to.
    Give a man a fish and he will be fed for a day. Teach a man to fish and he will promptly forget that he once did not know, and proceed to call anyone who asks, a n00b and flame them on the boards for being stupid.

      sounds like you need to drive it more often, cars don't like to sit
      '88 Colony Park, white with wood grain contact paper, K code axle, hose pliers on heater hoses, factory duals, big plans in the future...

      '83 Toyota 4x4, 31x10.50 15, could use a new carb, custom humidifying holes in the roof, mud based paint...

        Ah, now a scientific reason for the mystery leaks:

        The pan gasket.

        It contracts and expands with heat. When it's cold...and cold for an extended time...it really shrinks. When you drive it, it heats up...and expands....mystery leak now gone.

        Just think of what most of you are running for pan gaskets; either cork, or paper gasket material. Neither of them seal all that well, compared to steel-core rubber gaskets, like you see on most later 4R70W transmissions....which is what I run when I do a large-capacity pan upgrade for the AOD, which is to use a 4R70W 4x4 pan, and drill a hole for the one offset bolt so it will seal in the corner (AOD and 4R70W pan bolt hole patterns are similar, except for one bolt). With the new metal/rubber gasket...even seepage when cold is gone.

          If it's leaking, I wouldn't flush it with something like SeaFoam or any other flushing additive for that matter. You may break more things loose, causing more leaks. I'd do a filter change, and add a quart Lucas to your transmission, that's the additive you'll see the most results from.

          You can also use High Mileage transmission fluid along with the Lucas when you change the filter, Castrol and Valvoline have very good high mileage transmission fluids. It may not be a high mileage transmission, but it definately won't hurt.
