Thank you for your fast reply!
Yes, I was driving in auto selection. When I pull down the auto stick from D to the - + zone while in Drive position, is it supposed to be in manual mode? If it is true, I tried today. No matter how I switch the stick to right + or left -, still D, no gear number showed.
Maybe something is malfunctioning with the 62TE, I can felt the auto transmission doesn't like to up gear but very like to down gear, the result is high engine rpm, like 3500rpm, even I only press the accelerator pedal very gently.
Tomorrow I will go to 郑州北环汽配大世界, hope I can find some machinist to diagnose it.
I forgot to mention I'm in China. Dodge Journey is a niche model here that few people know, so I came here
Thanks again!
