Hi everyone, been around a long time but first post. I have a 2004 GT 140k on it. It feel like it shifts into 2nd RPM drops a little when it engages but then i notice the RPM jump a few hundred and it feels like it engages again but settles down into the same RPM and speed as it if it shifted into gear maybe not all the way then locked in anyone know what might cause that? The shift point also seems to have changed if thats possible sometimes it shifts around 1300 RPM?
