I'm having a strange issue with my auto tranny (I think),
every now and then, when I downshift a few times (by depressing the pedal, or by using the gear shifter +/-), The VSC/TRC lights will go on, the issue is intermittent and will always disappear when I turn the car off and on again.
I plugged the car into Techstream and I found error C1203 and freeze frame data, looking into the data (see image below), I notice that Shift Lever Position says Fail.
Does that mean the electronics in my lever are toast ? note that when I bought the car and was installing a new radio, I found there was a huge liquid spill in the whole centre console area, sticky old cola
my guess is that there's something wrong with the shift lever, but someone probably knows something better than I do here!
any tips what to look for, or how to debug this issue ?
P.S: I've reset the code, but of course it comes back again, freeze frame data is also still the same, so this is the only issue.
