My first suspicion is the Transmission Range Switch getting unreliable. It's operated by the shifter. My second suspicion is that the transmisson fluid is dirty (or low) or you have a sticking shift solenoid or two, could be caused by dirty fluid or just wear. If the fluid is clean. transparent and pink, fluid's not the problem. Do you ever see the malfunction indicator light (check engine or transmission light) on, especially when this is happening? If so, there are probably stored diagnostic trouble codes in the computer and these could be scanned by a mechanic and give you a better idea of what's up. If the fluid's dirty or burnt smelling, you probably need to do a transmission flush (replace all the fluid and filter) and see if that helps. Don't you have an "Overdrive Off" switch? That may be worn out or dirty and causing an intermittent problem too, so be aware of that.
