I have a 2003 Ram 5.7 with 56k on it. Last night the transmission went into limp mode and the check engine light came on. I haven't noticed previous abnormal behavior with the transmission. I checked the fluid hot and it seemed a little low, but I only topped it off with half a quart.
I scanned the codes and get:
P0700 - transmission control system malfunction
P0846 - Transmission Fluid Pressure Sensor/Switch “B” Circuit Range/Performance
P0871 - Transmission Fluid Pressure Sensor/Switch “C” Circuit Range/Performance
P0988 - Transmission Fluid Pressure Sensor / Switch E Circuit Range Performance
P0876 - Transmission Fluid Pressure Sensor/Switch 'D' Circuit Range/Performance
P0888 - Tranmssion Relay always off
Any advice on where to start? I don't know much about transmissions, but the 4 fluid pressure codes have me thinking sensor or wiring to it, but do they all refer to one sensor? Thanks.
