06 LE here. I had the second gear slipping at around 7000 miles. I originally thought it was my rear tire spinning which gave me a reason to put some sportec m3's on it. Still had problem. I took it to the dealer and they told me nothing wrong. Left dealer opened her up and still slipping turned back around back to dealer. After they tore the trans open and found a bend shift fork and worn gears. Funny thing is they also found a my clutch cover was cracked and the crack widened when they pulled in the clutch, which led them to believe that clutch wasn't fully disengaging and reassured me that Suzuki would/should fix all under warranty. So I signed paperwork to pay for repairs in the rare case that the warranty wouldn't cover it. Suzuki rep said no way would they cover it. The dealer doing the work said that it was bull but it was Suzuki Corp's call. So I purchased undercut trans from Orient Express, Factory Pro Shift kit, Ape Tool steel shift fork shaft and dealer put them in at no extra charge. Should be rock solid now. Now I have 10,000 miles on her and she shifts better than ever. I thought about taking Suzuki to court but probably will just forget about it unless there is a class action or something.
