Transmission problem
1994 GMC Sonoma 6 cyl Four Wheel Drive Automatic 200K+ miles
----------------------------------------------------------------
I had the transmission filter and fluid changed and the catalytic converter replaced in February. Now I have a rattle noise whenever I'm stopped and in gear(stop sign, red light, etc.). As soon as I start going again or put the truck in park the noise goes away. Any ideas on what it might be? thanks.
