First thing is have you tried the transmission relearn procedure in the owners manual? If not, give it a shot. Have you scanned for OBD codes?

Can't engage reverse or drive...
This just started happening - Car starts, shifter shifts but when you try and engage reverse or drive - nothing happens. Shutting it off and restarting sometimes works to fix it, but I'd hate to get stranded. Any ideas?
