My subie just started throwing these three codes two days ago:
P0700 -> Request AT Malfunction Indicator Light (MIL) On
P0771 -> Shift Solenoid E Malfunction
P1798 -> Gear 1 Engine Breaks
CEL, Sport & Cruise lights all on / blinking, occurred at low speed when turning out of parking lot, drive way, etc. I've reset the codes twice, and they come back.
The second time this happened the car wouldn't shift out of first gear, despite showing higher gears on the display in the dash in manual mode.
Some of the posts for related codes here on the forum recommend flushing fluids and changing the filter, which I had done earlier today. Cleared the codes after replacing fluids, and was able to drive for about 20ish minutes (including freeway), and all was well. Stopped at the shop, said the codes hadn't come back, and went to turn out and they all came back.
I've searched for the three codes here on the board, but was hoping to see if anyone had experienced these codes as well, and if there was any additional insight to next steps. We've replaced the fluid / filter, to no avail. Checking the connectors is next I think, and this might sound like a rudimentary question, but how do we tell if they're bad?
Oh, and not sure if it holds any bearing, but it's COLD here...
