    I was able to get the inner seal out but it took some doing. Getting the new X seal in was difficult too but it is in properly with no incident regarding the retaining washer which seems to be held in place to a better degree. My oil pan was showing some dampness so I am replacing the pan gasket as well. The outer retaining ring popped out when I got too forceful with a curved screwdriver that I was working with to remove the seal. The outer retaining washer is now seated, and I am going to stake it today as a means to prevent it from popping out when shifting.

    The old seals were hard and difficult to remove.

    Here is a picture of the retaining washer staked in. Looks like I need one more at around 0430 hours. The block is very soft. It was quite a bit easier to move block metal Image Unavailable, Please Login than it was staking in the new front sight on my 1911.

    Ask your dentist of a couple of old picks, next time you 'visit.'

    They'll usually 'cough-up' a couple.


    DO NOT mention '... for gun cleaning' unless you KNOW he/she is a shooter.

    IF they are, then by all means mention it.

    They then might even 'UP' the number of picks they give you.


    Last time I asked for 'a couple' and walked away with over 20 old picks of various shapes.

    ARRGGHHHH!!!! I can't take it anymore! Those are called Explorers, not picks. You can buy a set of them at Harbor Freight for much less than Tommy or I have to pay. They aren't very strong vis a vis pulling anything stuck in a car.

    I have dental picks that I obtained from a dentist. I was not able to remove the 32 year old seals with them so I made a stout one. It was a little bit too stout and I managed to pop out the external retaining ring.

    I hope the X seals loosen with use. They are fairly tight.

    Hm, I thought dentists have the best of the best. Back when my daughter had braces, one of the spring came loose and was poking her in the mouth. I tried to snip it with my automotive side cutter and it did not make a dent. The dentist just cut it off with his cutter, like that.

    They will, but it won't happen overnight - mine took a couple of thousand miles.

    Stock seals work fine and don't have that issue.

    I imagine they probably do. Like most people when I did it I was looking for what was theoretically a "better solution" (I had the engine out at the time & it was a "while you are in there" job).

    As is sometimes the case what seemed to be a good idea had unintended/unexpected consequences & they took longer to loosen up than I would have hoped for/expected. On the other side of that, they have loosened up & theoretically they should be a good , long lasting solution (at least they better be!) . You pays your money...….:)

    And what was not a good long lasting solution about what we had? Most I replace are so old they are hard and break on removal. It takes a very long time for rubber to do that.
    Improvement is good but I have yet to see an improvement.

    I did oil up the X seals prior to inserting the shift shaft. I also wonder if I made the right decision in not using the standard seals. After all, the originals lasted 32 years. Can't complain about that. I don't like the tightness of the X seals.

    Yesterday I put the engine oil pan back on. Gaskets for oil and tranny pan were purchased from Ricambi. I have reattached the shift rod yokes and turn buckle. I had carefully measured the distance from the end of the shift rod threaded section where it gets larger in diameter to the end of the yoke with the transmission in neutral with spring loaded balls in place so nothing moved inside the tranny. Used calipers so distance is accurate.

    Tomorrow I'll add engine oil. Will also close up the tranny tomorrow. I have Permatex Red RTV and a new gasket. Will the red RTV suffice?

    One other question. Is the at rest engine oil level above or below the shift rod? I installed the dip stick this morning and would have to take it off again to determine this. So if anyone knows for sure, it would save me some work.

    The x rings I installed on mine have no stiffness.

    I haven't done the math of "volume of oil" vs "dimensions of sump", but I suspect the rod is somewhat submerged in oil at rest. (Thus oil will leak from the front, if a bad seal.) There's 9+ qts down there at full rest. Otherwise, why would we drain the oil to do this procedure?

    Some people use no sealant - and I believe that's the best approach if you can make that work for you. I'm not a fan of Permatex Red for the pan seals (or other seals on the car made of that paper/laminate material). I use Permatex Ultra Black when I find sealant necessary. Be sure to observe the cure/torque times. Also be sure you torque the pan nuts in the correct order. Trust me, it ends badly (eventually) if you don't.

    you need to use the Permatex for gear oil on the cambio pan. I use a thin smear on both pans

    As above. And do the full torque over 2-3 passes, not all at once.

    Engine oil level is considerably above the shift rod. Oil volume is over two gallons. A gallon is 231 cubic inches. Oil pan is 5" X 15" so about 75 square inches. Divide 462+ by 75 and you get over 6 inches of oil standing in the pan. Shift rod is definitely submerged.

    I followed the instruction on the Permatex packaging for the oil pan which agrees with you advisors are saying.

    Looks like the sealant will be Permatex 81182, gear oil RTV.

    If oil is getting to the studs and dripping down past the nut (which the studs are in a blind hole) then your gasket seal failed. Just saying.....

    I use klingersil gaskets dry with no oil leaks. But others have various opinions I’m sure.....
