M47 Transmission Sloppy Shifting 200 1991

Hello all,
I recently bought a 1991 240 sedan, about 154,000 miles, with a M47 transmission that was replaced last December (2008). The gear shifter was extremely sloppy side to side, and I noticed red RTV had been gooped on the bottom of the shift lever bushings and pin, to the point I couldn't tell if there were bushings or not. So, I bought a new pin, two bushings and the O'ring that fits on the right side of the forked shift rod and assembled it. Much better, but still sloppy. Looking more closely, I see a "barrel" connector with two roll pins, 90 degrees offset between each other, forward of this connection, connecting the forked rod to the actual shifter input shaft into the transmission. There is significant lost motion axially (side to side at the gear selector) between the barrel connector and the shaft going into the transmission. My question is, does anyone know if the roll pins in question are held by the barrel or the shafts, my connection being so entirely filthy that I presently can't tell where the real wear is, not to mention that if the actual input shaft roll pin hole is worn, it might be a problem to fix.

Anyone have experience with this?
Thanks!

Dave Milo

BTW, I have a 1993 240 wagon with the same transmission, so I know what a "good one" feels like; much less sloppy.

    M47 Transmission Sloppy Shifting 200 1991

    Just to follow up on this, I replaced the shift linkage barrel joint, two pins, o'ring and spring steel sleeve yesterday while I was replacing the drive shaft support bearing. For me, the forward drive shaft coupling definitely needed to be out of the way, but I didn't need to lower the transmission.

    The difference with the new parts is surprising to say the least; shifting was previously vague, and required exaggerated shifter movement to from 4th to 5th. With the new parts, I was able to readjust the reverse lockout plate properly as well, and now all the gaits are spaced properly.

    After my wife drove it, she said that I had successfully demystified the shifter.

    Thanks again to all the folks that replied, I really appreciated the information and help.

    Funny you mention the location of the slop. After doing mine ( back in '06) I still seem to have movement in that same location. There's no play from the Barrel and pin to the Shifter but there is side to side slop from the front Barrel pin to the transmission shaft. I've been thinking about revisiting it to see if the forward Barrel holes have become oblong.

    If you can see the pins then something is missing. The pins are held in place by a sleeve-like spring (or spring-like sleeve) that fits around the barrel you mentioned.

      You are right, I can't see any pins. I am looking at a page from the electronic parts catalog from the dealership, "43 : Shift control M47 -1991". I'm looking at items 7, 8, and 9, but I didn't realize that item 8 must be the sleeve / spring that you are referring to. I just know that when looking at that sleeve while the shifter is moved side to side, there is a lot of lost motion before the actual input shaft to the transmission itself starts to rotate.

      I guess I will order those parts before I take the old ones out and see what is really worn.

      Thanks,

      Dave Milo

        As mentioned, The two pins (Part # 381528) fit snug through the barrel and the Shafts then a Retaining Sleeve (Part # 381527) fits over the barrel to hold the pins in place.
        Do yourself a favor, Get this retainer started on the end of the Barrel before installing the Barrel onto the end of the shafts..put the pins in and push the sleeve to cover the pins.
        I was able to do this job with the Trani in but I think I took the Driveshaft out.
