You know, after owning the truck for almost a year know,it's been a pleasure upon till last week. I had to make a delivery and had a 02 GMC Rcab Sbed SLE Z71 on the trailer in the picture behind it and the torque converter was ratteling every time it went into OD lock up. Is this common on these gas jobs?I did not think the 5.4 l had enough tourque to tear up a tranny. 70k km on her. Guess I'll bring her down to the shop.Only money spent on her was new tires ,gas & oil .She sure rides like a truck though with them X springs out front with no plow.
