We had a '98, hi-milage(over 150K on the odo),we used for our company. About 3 years ago our van had similar problems and the mechanic that did all the service work on our company vehicles told us it was the T-case after inspecting it, he'd seen similar problems in other Astros/Safaris. He got a used one out of the boneyard. About $600 later we got the van back and as far as I know it is still in use. FWIW
