Im not a transmission guy, but I would have that looked at soon. They are hydraulic units and when they begin to have problems/make noise it needs to be seen to before it causes other damage

So you don't think that flushing the transmission and changing the filter will help the problem

I have a 2001 Venture doing the same thing. What did you do? Did you have a good result?
