SEL and CEL Flashing on and off. Only code found= U1016 (loss of coms with BCM)
What is your question?
Just had rebuilt transmission and picked up car today. Took in because service SEL was coming on intermittently and then would stay on after driving 30min with hard shifts and had a tranny code P1811. Also getting CEL light intermittently with RPM dropping to zero and then spiking back to normal. Got car back today and tranny shifts fine now but still have intermittent CEL and SEL lights along with RPM spiking and now getting code of U1016 (Loss of Communication with BCM). Before taking it to shop had friend look at it and he says he was getting code of P300 and P301 (random misfire and cylinder 1 misfire). Told service guy about the P300 & 301 but shop can't get these codes. Don' know what to do about this money pit car. Any help would be great! Thanks!
