Have you owned this since new or did you buy it used? It could be your torque convereter not locking or unlocking correctly. Could be a selonoid hanging. At 110,000 miles, the van should of had 3 fluid/filter changes unless you run something like AMSOIL. I put AMSOIL in my tranny at the 30,000 mile mark by just doing a pan drop fluid/filter change. Then did a FULL fluid replacement at 100,000 miles. Transmission still shifts today at 111,000 miles like it did the day I test drove it at the Dealer with 2 miles on it.
