Trouble downshifting into 2nd gear

Greetings all,

My second gear is getting "crunchy." Occasionally accidentally grind it while shifting. It is no problem when I'm accelerating, but when I'm decelerating, like cornering, I have to be very careful and slow getting it into second to avoid grinding the gears. I occasionally can manage to touch the gas a bit to speed up the engine a bit which helps, but is difficult to do.

Any insights on what the cause is? I expect I'm looking at a gearbox rebuild in the not so distant future...

Thanks!

Weak synchro on 2nd gear. Keep practicing double de clutching, you will soon get the hang of it :)

As above - double de-clutch! Or - just DON'T change down into second gear on the move, unless you absolutely need to !! The box will likely need a new second gear and possibly a selector hub too - and certainly syncro rings -as well as new bearings throughout and a new layshaft. Start looking for a good spare secondhand gearbox...... meantime take good care of the one you have - perhaps treat it to an oil change - with 20W50 engine oil......
