Yes you might be right because when im in second gear there is a cut back when you reach high rpms. There is like a bit of a lag then boosts lag then boosts. I went to a european auto and he said it might be the transmision. There is like a bit of a lag then boosts lag then boosts. But the noise only appears when im in low revs. It is like a Trrrrrrrr noise. But eventually goes away.
Thanks for your help.
