SATURN VUE ENGINE PROBLEM

2005 Saturn Vue • 130,000 miles

On the tcm, what do the letters YJKU stand for? Serial #12202143 on tcm. Can I replace unit with same model # but defferent letters?

Do you have a 4cyl or V6 engine?Not sure what the letters mean but if I get a little more info I can help you out. So why does it need a TCM?

That's the only code you have?Does it run rough at idle and down the road like you have a engine miss?

Only code, it runs rough at idle, wont accelerate engine in power saver mode (engine light with downward arrow)

It does say reset the code ad if the code comes back you have a bad to replace the tcm. Not sure what years will work if you get a used tcm make sure you get it reflashed at the dealer.
