Could be a faulty VSS (vehicle speed sensor). Does the trans shift properly? If so the VSS may be ok and it is a problem in the dash or wiring. The VSS has to be sending a good signal to the PCM for it to shift the trans properly, if the VSS is the issue, the trans most likely would be shifting erratic as well
