From Alldata DIY:

DTC Descriptor
DTC P0700
Transmission Control Module (TCM) Requested MIL Illumination
Circuit/System Description

The diagnostic trouble code (DTC) indicates that an emission related transmission DTC set in the transmission control module (TCM). The engine control module (ECM) receives the TCM information over the serial data circuit. The ECM turns ON the malfunction indicator lamp (MIL) when the TCM sends a message over the serial data circuit requesting MIL illumination. The DTC information for the ECM will only display DTC P0700, but the Freeze Frame/Failure Records data will display the transmission DTC that set.

Couldn't find an explanation of P1825 code- try Google. May be specific to transmission as P0700 looks like generic TCM problem.
