It`s usually 3rd that goes crunch. Maybe bleed the clutch slave cylinder and check that your seat position is getting full travel on the clutch pedal. It is important that the correct oil is in the box, if in doubt change it, the wrong oil will wear out the syncro. cones. 3rd-2nd is a different syncro. cone from 1st- 2nd so maybe worn. P.S. unless in traffic I don`t use 1st gear, the car will pull away just as quick in 2nd if you use low revs. I did a 0-60 back to back test using 1st -2nd and 2nd only and the times were identical! Actually, most of the time it`s a 3 speed box just like the early cars !!
