95 Eurovan Trans

Has anyone out there had shifting issues on a 1995 VW Eurovan camper?
Purchased just this week with only 15,000 miles on it and it is shifting very hard while rolling down the road. Automatic trans. please help if you have any knowledge on this model/year.
Thanks Renee

if its a 1995 and only has 15k miles on it I am sure its been sitting for SO long that the internal parts of the transmission have rusted and the fluid has not been able to flow through the transmission like it normally would.
