I have noticed that mine does the same thing...the servo shifts the forward/reverse fine but at times, it won't go into full engagement and I have to move the truck a little for it to click into place......the only thing I did was upgrade the servo from the stock to one of the ones that come with the stock LST for steering....centered it right and have tried every thing possible on the radio for EPA....if anyone can throw a dog a bone..lt me know!
