Buck_ss03 Posted November 28, 2015 Report Share Posted November 28, 2015 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.

EXGM Posted November 28, 2015 Report Share Posted November 28, 2015 First step scan for codes. Even if your check engine light isn't on but my guess it is or will it soon it will give you a better idea what's going on or where to start.....
