Hello,
I have a 90 Chrysler Lebaron which had a bad transmission in it. It has now been replaced and can shift into 1st, 2nd while in drive, but will not shift into 3rd gear or the overdrive. The distance sensor has been replaced but I have no ideah what the other sensors are on the transmission. It looks like they count the splines on the gears on the inside. Any help would be appreciated.

Optional Information:
1990 Chrysler Lebaron 4.0
