i just bought a v6 auto lebaron last week, and when i was driving it today i noticed a problem. now this is the first automatic car i have ever owned, so i am a bit ignorant in their interworkings. i know many of you on here can help me out. i searched but couldnt find any threads relating to my problem. when i give the car gas... say 3/4 to full throttle and whined out a gear the car will bounce off the limiter, shift into the next gear and stay in the next gear. i was on the highway today floored it and it stuck into 3rd (and would not upshift). this is the third time its done it in a week. the car only has 76k miles and the transmission is only two years old, has plenty of fluid and ect. when i stop the car and turn it off, and turn it right back on again the problem is solved and i can continue driving normally. anyone have any ideas for me to check??? it would be much appreciated.
