Sounds to me like your 2nd gear Syncros are shot......I copied this from another site:

<U>So what does the syncro do?</U> It provides a mechanical bridge between the outer sleeve of the selector and the matching gears on 2nd gear. As the sleeve encounters the syncro, it engages it easily since the teeth are cone shaped... designed for this. Then the syncro helps to spin up the 2nd gear to the same speed as the selector sleeve via the cone shaped, friction fit between the syncro and the gear. This allows the sleeve to then slide over the matching portion of 2nd gear without grinding off teeth. As you use the transmission, the friction surface and cone shaped teeth of the syncos wear and become less effective. Eventually, you have to replace the syncros...
