Transmission problem
2002 GMC C1500 V8 Four Wheel Drive Automatic 138,00 miles
----------------------------------------------------------------
I have a 2002 gmc sierra 4x4 with 138,000 miles.Everytime i am slowing to a stop ,when the transmission downshifts i hear a clanking noise.i was suspecting the u-joints are going bad but i'm not sure.I also hear this noise sometimes when i put the transmission in gear. thanks.
