2003 Neon Transmission issue
My sister's Neon is giving a code 700 and going in and out of limp mode. Mechanic is saying it's the TCM, but I'm leaning towards something else because it doesn't stay in li p mode, and I'm not reseting the computer. It started after getting new speed sensors.
1st question, on the 2003 Neons, are the ECU and TCM one whole unit Or separate modules?
And any ideas what else it can be?
