My 07 Silverado LTZ Crew Cab 6.0L has 81000 on it. I noticed a fifty cent size drip on my garage floor. It looks to me it is coming from the Trans cooler lines. Any body replace these before? How much you think the lines would cost? I think I could replace them my self. Dealer said not part of the Drive train warranty. (Figure That) If ant body has done this could you send some good direction? Going to Sturgis in August pulling a 7x12 inclosed trailer with two touring bikes, don't want to chance a busted trans out west. Thanks for any help.

This is a pretty common problem. Some guys just remove the factory crimps and replace the rubber part of the line and use clamps to hold the new hose in place. If you go this route I would suggest using fuel injection hose clamps. They clamp much better that regular worm style clamps.
