One problem related to transmission gear slipping has been reported for the 1998 Plymouth Voyager. The most recently reported issues are listed below.
Transmission failed on this vehicle. Van would not move forward or backward. I have another 98 Plymouth Voyager that is also used as a delivery van and it is experiencing some of thesame traits as this one. It will hesitate when put into gear and sometimes slip when starting from a stopped position. This is exactly what the van that has been fixed was doing. Chrysler paid for the parts on the van and I paid for labor. There appears to be some bulletins already on the books that pertain to these problems with the transmission.
