since you are considering options..
might as well be aware of another choice..
which is to have your trans rebuilt using a syncro case ...
that way you can have a 2WD 4 speed trans, with vacuum actuated locking
rear differential ..
ala stock syncro .

I have since inspected and checked the torque on the engine and tranny mounts and all seem within spec. I have also confirmed that I do not get this movement in first or second gear. Short of dropping the tranny, what other diagnostic tests can be used to confirm/refute Dennis' rather expensive hypothesis?

I was thinking about updating that one then swapping out my current transmission {I also have a line on a 5-spd ASR transmission, but it has a diesel bell housing and would require finding a 5-spd linkage. However it does have a 40% LSD. It is also significantly more money).

I actually had to use the TDi Jetta to pull the Vanagon out of the wilderness that is our lawn the other day. You would think such an undignified event would have shamed the Hyena {or at least its owner} into not parking on wet surfaces, but less than days later a similar event occurred climbing out a drive at a friends cottage. I have started investigating adding a limited slip or torque biasing differential to the tranny when rebuilt, but the projected cost is not encouraging .... I have only found one or two offerings (and suspect they may both be manufactured by the same provider) and the cost is more than what I would pay for the tranny itself.
