Today my 03' SS started to shift very heavy. From 1-2 it would rev pass 3k. The shift time was very high pass 5sec which is not suppose to do. 2-3 is fine and 3-4 is good also. But than coming to a stop she will stay in 4th gear and not drop down to first. If I manually down shift she will give me first than I shift to second and she's good and so on but that's manually shifting her and she shifts perfect. So the transmission could have not gone out. I do not race in her I don't just randomly dog her around everywhere. I don't even daily her. Was just a good day to drive her and started acting up. I've seen millions of forums and googles and searched everywhere and get different answers which is a headache. ***I hear that my transmission needs a rebuild...than I hear it's a wiring problem....than they say it's a PCM problem...if not that it could be a speed sensor. All that is done to her is a Torquer v2 cam Circle D 3600 converter 243 heads with .660 lift springs Tbss Intake manifold/ tbss throttle body 1 7/8 long tube pace setter headers Volant CAI If anyone could give me any info that would be a big help. Thanks
