After doing a complete rear brakes job (pads, rotors, caliper bracket & ABS sensor) on my 2012 Jeep Wrangler Sahara myself, we ran into several problems. The sensors were after market from NAPA as were all the other parts. The dash is still showing ABS traction alert. It's now also showing the emergency brake alert and a engine light alert. To make matters worse, my transmission will now not shift out of 1st gear nor will the auto shift stick show 1st or 2nd when I try to use it manually. It's at the dealer now. Rep said it sounds like the sensors are screwing up the computer since it is after market sensors. Any one else experienced anything like this? The transmission issue showed up the day after the sensor & brake replacements.
