I are a relative expert on this subject and know more than i care too. After replacing every stinking bushing from the tranny back and down to the transverse link, I pulled it apart one more time and found a small hairline crack about 2 inches long at the mounting bolt in the crossmember. Welded it and cured the problem. Other forums have another answer you may not have noticed and that is the wallowing (SP) out of tranny mount bolts allowing it to move forward and backward. good luck, squid
