I didn't want to hijack the other thread for this, but would like to know more about this. Is that the spider-gear shaft that gets loose? What is there to keep it retained? This sounds exactly like what can happen on S-series Saturns. Those have a split-type spring pin to hold the spider shaft, not locking screws like I am familiar with. The best fix for the Saturns seems to be drilling everything over-size and using a spiral-type spring pin. When I first heard about this in the Saturns I was amazed, as I had never heard of spider shafts coming loose before. Now there are two different transaxle designs, by two different manufacturers that have this defect???
