I have an 06 TJ with an automatic transmission. About 2 months ago it started to shift hard into 2nd gear from 1st. I took it to the dealer & they replaced the filter inside of the transmission. It worked great for about 2 weeks, so I took it back in & they said it was the sensor in the transmission. They changed it. Last week it started up again.
Has anyone had tis problem? If so, what did it take to fix this problem?
