    Hello,

    Sometimes when i power off my 2008 prius I'll hear a beep for a few seconds and the transmission shift display will stay lit for the duration of the beep before going off. No warning lights are come on. Does anyone know what could be causing this to happen?

    Happy Holidays to all who celebrate,

    Perhaps that display remains lighted until the transmission's shift into Park is complete. I don't know for sure though.

    I had a gen 1, which had to be manually shifted to Park. (Gen 1 just had a big shift lever. It made all the "gear" selections electronically, but moved an actual mechanical cable to park and unpark.) The PRNDB display on the dash would just stay lighted after you turned the key off, until you remembered to shift to P. I thought it was a kind of tasteful, low-key way of doing a reminder.

    Since it is not a real transmission, wonder if there are any solenoids that can cause this.
