Got my car back from dealer they calibrate transmission ECU. Now the car and transmission run good. Before I got check engine light transmission was slipping, and one awhile stuck on 3rd gear. Was going to flush and change transmission oil, but dealer say don't needed to.

 

that's great news. Hopefully your transmission will be trouble free for miles to come.

 

I'm happy I didn't need new transmission. I'll drive around for a week and see if check engine light will come back. But I still want my transmission flush next time. Dealer say no needed, but CL member have experience smoother, shifting after flush or transmission oil change.

 

So there's a trans calibration update available to us? Did they say why a new calibration was made available? Better than the factory ones I assume? Hmmmm.

 

Seem to shift faster and no delay like before. I watch it in display gear.
10 mph it go to 2nd gear
20 mph it go to 3rd
30 mph 4th gear
40 mph 5th gear.

 

^I only exclusively use the gear # display on my cluster.

Might inquire about this trans "reflash" next time I'm at the dealership.
