My 2003 with only 67,000 on it is exhibiting strange behavior. On a recent ride, when accelerating, it seemed to slip out of gear, and went "zing" up the RPM scale. When I let off the throttle, it regained the gear and was fine. Here is what I am noticing; In 1st and 2nd gear, there is no problem at all. When I upshift or downshift there is no problem at all. But in 3rd 4th and 5th, when I give it a little "too much" gas. it goes off the gear and winds out. Again, when I let off, it regains the gear and becomes normal. Now, If I am careful and accelerate slowly and steadily, there is no problem. Has anyone seen this before? Thanks for your help and expertise!
