Hi and thanks to take the time to read my story.
I just bought a Silverado 1500 6 cil. Mod. 2007
Everything works great except the gearbox make the trrrrrr noise when I engage the third shift. All other works great.
I also feel that the clutch is a bit hard to press... I need more muscle or it's normal.
The first and the reverse engage without trouble.
Tomorrow I will check the oil inside the transmission.
Thanks for your help....
Mateo
