    M47 Fluid question 200 1989

    Might I recommend Jim's response to your previous M47 question?

    "I would flush and then add the redline MTL. It helps the shifts go a little smoother, especially when the weather gets cold. Make sure you overfill by jacking the car up high on the filler side and injecting as much of 2 quarts of fluid as possible."

      M47 Fluid question 200 1989

      Ok, well IPD sold me 3 qts saying I needed a little bit more than 2... Which is why I asked. Typically when you get conflicting answers, you ask again, which is what I'm doing. Since I haven't done it yet, I want to be sure. But I'll take that as your recommendation for the correct answer, bold letters and all.

        M47 Fluid question 200 1989

        hi borkeroo- i was wondering about this question too. my 92 240 m47 owners manual says 1.6 quarts. if you drained trans and refilled with 2 quarts it would be slightly overfilled and would dribble out the refill hole if the trans was level. curious why one should overfill trans. instructions on all my other manual trans (american cars) was to fill level trans to point where fluid just begins to dribble out the fill hole, then plug it. if you overfilled those transmissions, fluid might leak out the input bearing shaft gasket or tail shaft(where it bolts up to driveshaft). but thats american manuals which probabl have looser tolerances than the m47. im a newbie to volvos and am eager to learn new things from the sages here. logically you would want enough fluid in the trans to submerge or partially submerge the gear shafts in lubricant. hope a sage here chimes in on my thinking borkeroo. thanks tons oldduke

          M47 Fluid question 200 1989

          In answer to your question, the M47's fill hole is slightly lower than it should be to allow fluid to completely lubricate the upper bearings in the gearbox. If you only fill to the level of the hole, the bearings do not get adequate lubrication and don't have as long a life as the properly lubricated ones. By jacking up the fill hole side of the car as high as possible, you are able to overfill the case and lubricate those upper bearings completely.

            M47 Fluid question 200 1989

            Ok, but if this is proper procedure, then how would mechanics be expected to do this on a proper car lift? Not that I am one, but I'm just wondering.. Or do they have to get out a jack, and get on the floor like the rest of us?

              1.6 quarts is the book spec for the M47.

              I suspect that IPD said 3 quarts by confusing the M47 with the M46, which requires a good deal more fluid.
