Yup, everyone is on the money. If I was in your shoes I would:

1) Check trans fluid level and color. If it is low or BLACK and smells like burnt cookies than you should

2) Do a full trans service. Change the tranny filter and replace fluid with a good synthetic ATF. If that does not fix the problem right away, than I would

3) Look into the Mode Switch as this has caused trouble for people in the past.

When I bought my VX, I experienced some very hard shifting. Shortly thereafter, I changed my tranny filter and put in Mobile-1 ATF. Problem fixed. There is a process for checking the fluid level properly, so be sure to search the forum for that info.
