P1815 is usually caused by one of the M-Mode switch contacts "falsing" and causing the tranny to see two gears at once. On some shifters like older Altimas the microswitches were exposed and could be replaced, but on the R51 it pretty much means a new shifter because the contacts are inside the shaft and pivot assembly.
