you need a scan tool to verify a signal from the trans is reaching the pcm. if it is, you have a failed dash cluster. if not then the reason needs to be determined.

a shop has the actual scan tool you need. get some help with this

yes, you can but it needs to be verified with a scan tool, not a guess. it is expensive if it is the cluster
