I have a 2002 Chrysler Sebring convertible and the transmission leaked and when low on fluid. After having the leak fixed the transmission now shifts fine except when down shifting from 4th to 3rd gear. I heard that the transmission computer needs to be reset since when it went low the computer increased the pressure and the only way to fix it is to reset it. I tried disconnecting the battery for a few minutes but that didn't work. Any ideas would be appreciated.

Thank YOu
