2WD/4WD indicator lights off
Some time ago I have noticed that my 2WD/4WD indicator light started to blink from time to time during driving. I was on holiday with no possibility to check anything.
Coming back home they completely switched off and I found to early switching gears by my AT and error 1875 came on.
Now I almost can not drive - no errors, but fourth gear is turning on at 20MPH, no any 2WD/4WD indictor on.
Today I have replaced switch (version with 2Hi, 4Hi, 4Lo without auto 4WD) and TCCM but no effect.
Any suggestions what to do next?
