Sadly on the 4th day of a 20d trip, 1500m from home our AT4 developed a trans leak at the tail of the Allison joining the xfer case. Only 17100m and the trans is being dropped in Gallup NM. Fluid is weeping between the case join then forming a slow drip. (10months of planning and a few thousand $$ blown on what we expected to be the last thing to ever cause an issue) This is NOT any of the reported line leaks... pan gasket and such. Our local dealer in Loganville offered zero assistance (eg. where we could take it..... nothing other than sorry to hear).
