Trans issue or engine misfire?? While starting off, occasionally has a hic-cup where engine misses or trans slip (5-10 MPH. On a steep incline, inching forward feels like a nisfire. Engine light on but issue was months before light came on. 2 mechanics tried to find problem. Light on was a trans light code. ANY IDEAS???
Your description could be a transmission issue. What was the exact code (it should be in the form of “P0123.”)?
BTW you only need one message, not three. It works better with one.
