I bought a car for my granddaughter last Friday, she ccalled RJ Monday said it was shifting hard and he told her that the transmission filter needed change and new oil put in. okay,today, Thursday while she was driving it home started shifting hard again and started to heat up, she turned it off. Come to find out someone jerry rigged it. first thing Friday morning we're all headed down to RJ's to see what he's going to do about this. update Friday after we see RJ.
