Has the fluid level been kept topped up and has it been changed as per the schedule in the owner’s manual? Has the van been used for trailer towing? ---

When you say “oil”, do you mean transmission fluid? If so, was the correct transmission fluid used? Regardless, as mentioned above, replacing the fluid is a reasonable first step to see if that makes a difference. I suggest that you have this done at a good independent transmission shop. If that doesn’t fix the problem, then unfortunately you’re probably looking at a transmission replacement next, which I’d also recommend be done at that shop. ---
