If this is in the wrong section, someone please move it.
I have a 1998 Grand Prix GTP (Supercharged) with no mods at all except the Transmission was replaced a couple months ago. Transmission was from a Buick Regal (Same transmission as the 1998 GTP)
I made a few videos while I was driving...Maybe one of you guys can tell me what might be the problem with my car. Engine? Transmission? Torque Converter? I don't know...
While I'm driving you can see the speed consistently increase (I never change pressure on the gas peddle), but the RPMs stay the same for a bit then rapidly jump up and the speed increase at a faster rate too.
You can see in all the videos it gets to 23000-2500 RPMs then Jumps about 500 RPMs.
If anyone has any ideas I would really appreciate it. Don't mind the music playing in the background haha
10-11 seconds into the video it happens.
