Hey gang, 1st time poster here. My wife has an 06 gtp and lately from idle at first movement like when she's just backing out of the garage it clunks pretty loud when she puts it in reverse. sounds terrible. She also says when she gets backed out on the road and puts it in drive it makes a "screaching" noise. Whwn she got home from work today it smelled hot when she pulled it in the garage. I had the tranny slip yoke clunking on my silverado and replaced it and it went away. could it be something like that or what do you guys think?
