Maybe it is a vacuum problem? dunno...I'
ll drive it until it needs more attention.

You have a problem of thick ATF or a failing conductor plate. A conductor plate is basically a wiring harness but laid flat - but has 2 speed sensors built in.
The shift solenoids have little screens that sometimes can get dirty but an ATF change helps in these cases as the trans is pretty cleverly designed. All debris etc fall into the pan rather than getting stuck.
