    Here I have been walking around with a sharp claw in my stomac for over a month thinking tranny rebuild, converter failure, axle swapping and total bankrupt. And a new trannymount took it right away!! Also I used "metal-paste" to make the u-joint sit still in the slipyoke, that may have helped some to.

    I'l go do my happy-dance now. [​IMG][​IMG][​IMG][​IMG][​IMG][​IMG][​IMG][​IMG][​IMG][​IMG][​IMG][​IMG][​IMG][​IMG][​IMG]

    Did you replace the three missing flywheel bolts?

    I'v heard others saying there where only 3 bolts originally holding the flyweel and converter together on all the ones they had seen. It looks like there should be 6 though.

    Funny thing is the old mount looked fine untill I got it out.

    There are only 3 of the holes in the flexplate that get used. GM flexpates are drilled with dual bolt patterns, to fit multiple torque convertors without having to stock more parts. [​IMG]

    On your earlier post it sounded more like the bolts for the flywheel to the crank? Is this not the case?

    Don't ya hate it when that happens[​IMG]?!? I've been through it twice with these stupid tranny mounts - I've gotten to where I keep a spare around. I've got a design drawn up for a replacement using polyurethane leaf spring bushings, much like Autofab's engine mounts pugsley.alloffroad.com

    was it the rear d-shaft u-joint that wouldnt sit still in the yoke? mine did the same thing, and i fixed it by putting c-clips on the caps. it made the u-joint fit perfectly and even.

    I replaced my pinion shaft yoke, it was eating u joints and finally people were telling me my driveshaft was wobbling
    $140. and a new pinion nut, didn't change the seal or crush sleeve, just set the preload on the pinion shaft.

    It was the u-joint on the sliding yoke. The caps where wobbling in the yoke-ears. Originally I think they came with a epoxy-glue (at least my front u-joints had some, and I think I'm the first replacer of those.) Anyway, I could see the caps wobling a tiny bit but now they dont.
    My old trannymount could be stretched apart2 inches maybe, so that is where my shudder came from.powerfull 6.2 diesel trying to get 35" tires to start turning with 3.08 gearing. Put a lot of stress on the driveline, and the trannymount lifted enough for the rear driveshaft angles to start binding and shuddering.

    I also decided to put the c-clips on there when I changed the u-joint at the rear axle.
    I couldn't figure it out any other way. The worn out one I replaced didn't have any though. Wonder how they got it centered?

    They inject plastic in the yoke to hold it if it was a stock one. Usually when I remove those, they require a torch.
