Parting out a 94 940 wagon, tranny question 900

Bought a $425 wagon to help with my 2 940's and 89 240. Fully functional but for the AC. I'd keep it if I needed a car.

Thinking about keeping the tranny. As it is a big messy job, especially on one's back out in the driveway, I was wondering if I should run the thing dry using the coolant line method. Maybe I should refresh the fluid, drain and pull it. Any thoughts?

I would entertain any requests for parts, especially wagon specific parts

    you do not indicate your skill level or the tools..jack, engine crane, etc etc you may or may not own.

    if you bought a parts car and have few skills and fewer tools stick to the low hanging fruit.

    if you have skills and own some tools pulling a trans is much easier than installing one since gravity becomes your friend not your enemy and aligning the input shaft with the flex plate is unnecessary.

    if you are up to it i would

    first: remove the plate between the trans and engine exposing the flexplate and torque converter, now disconnect the driveshaft from the back of the transmission. using a 16 mm offset wrench remove the 4 bolts connecting the flexplate and torque converter. you will need to have the trans in neutral and you will find it easier to attach a socket to the front crankshaft bolt and turn the engine exposing the bolts one by one. a spark plug removed makes this effortless. if you can get this part done you have a good chance of finishing the job.

    then

    1. drain the transmission, disconnect or cut the cooling lines to it and cap them or crimp them such that no fluid leaks from them
    2. remove all the bellhousing bolts. the upper left one (above the starter) WILL give you a hard time because access is so bad..once or IF you can get them off
    3. place a transmission jack or some such device under the pan
    4. remove the transmission crossmember AFTER disconnecting the shifter linage from the transmission

    with the jack supporting the trasnmission disconnect it from the engine.
    the dipstick was removed early in the game

      Deat trichard,

      Hope you're well. Would it not be better - as the car is driveable - to flush the transmission twice (Wal-Mart followed by synthetic ATF) and store it "wet", rather than storing it "dry" (drained)?

      I ask, because leaving it dry seems likely to allow seals to dry-out and corrosion to form because air will be in places usually filled with ATF.

      Further, if it is stored dry, won't the pump run dry briefly (a few seconds) until the newly-filled ATF circulates?

      Or, will ATF - given time - form "gums" on all surfaces, turning the tranny into a paperweight?

      Thanks for your advice.

      Yours faithfully,

      Spook

        your points are well made for which i have no definitive answer.

        every transmission i have ever bought or seen in a reputable junkyard that was NOT on the car has been stored dry, sometimes for long periods.

        my own pulls are stored dry with cooling line capped or crimped close.
        i suspect transmission fluid being a tacky messy fluid sticks to every surface it touches long after the sump is gone.

        i think your concern is misplaced but that is only an opinion

        in new england we use it in a spray gun to undercoat a car which is then driven down a dry dusty road. it makes for excellent undercoating when combined with dry dust.

          Dear trichard,

          Hope you're well. Thank you, for sharing a key insight: "every transmission i have ever bought or seen in a reputable junkyard that was NOT on the car has been stored dry, sometimes for long periods."

          That answers my question: no need to leave fluid in the tranny. For, if "dry" storage did damage, no one would do it. I'd guess that after draining the pan, there's enough ATF on working surfaces to prevent damage, until fresh fluid circulates.

          Thanks for the education!!

          Yours faithfully,

    Dear j.pelchat,

    Hope you're well. I'd use a low-price plastic tarpaulin to protect the driveway. Before pulling the tranny, though, I'd flush it with cheap automatic transmission fluid (ATF) (Wal-Mart or local equivalent). As the car is driveable, I'd drive it for 1000 miles / 1,500 kilometers. I'd reflush with Mobil 1 Synthetic ATF or equivalent. I'd drain and remove the steel ATF pipes, cap the pipe openings, remove the tranny and store it. Before disconnecting the ATF pipes from the tranny, put rags under the pipe connections, to catch fluid drips.

    Storing the tranny "dry", i.e., without fluid in it, is likely to cause seals to dry-out. Further, by allowing air into places where air should not be, "dry storage" risks corrosion.

    Further, when a "stored-dry" tranny is re-activated and filled with ATF, the pump will have to run "dry" for a few seconds. As the shifter is moved, it will take a couple of minutes for ATF to displace air and coat all internal working surfaces. This brief "dry" running cannot be good, as ATF is both a coolant and a lubricant.

    The work involved in pulling a tranny is such that nothing should be done that might shorten the service life of the unit.

    Hope this helps.

    Yours faithfully,

    Spook

      great advice from all. I won't be able to put any miles on it as the registration is expired. I will probably change the fluid and drop it.

      T-Rich, I feel as though I can do this messy job as I have done it before. I don't have a proper jack but I'll get thru it

        try and keep the torque converted with the transmission as you drop it. it has a fair amount of fluid in it which won't drain unless you separate it from the trans.
