Hi there,
I'm a new comer to this site. I just dropped off my 2003 GMC Sierra truck this morning to a dealership. The first reason being, had a message saying check analog brakes. Also, the transmission going in and out of gear while driving, plus speedometer moving up and down quickly.

Secondly, Every time I make a turn, I hear this clunking noise like something sliding back and forth underneath the truck as I driving.

I would appreciate it if anyone out there could help me. Has anyone out there have any of these same problems?

Sincerely,
Silver
