So in summary I think you definitely are low on trans fluid and have been for a while, and you might have a trans fluid leak. First place to look is at the two coolant lines at the front of the VX. If you lay down under the front bumper and are directly in the middle of the VX the two black hoses connecting to metal lines are a little towards the passenger side and as close to the bumper as possible. If you see red fluid anywhere around there I would be concerned. Get that trans filled ASAP.
