the tranny is probably going out, but try a fluid and screen change. keep in mind if the tranny is going out, i have seen a fluid and screen change stop them from shifting altogether
Are you having trouble shifting out of park? Would it be a bad solenoid/tranny?
Yes, it is possible on an electronically controlled transmission.
