1st gear jumping out, 4th gear crunching, how do I fix it without changing gearbox

I think you misunderstood me , the box i got is in my car as a friend did me the courtesy of blowing the one i had in it ,it was 20 years old thou. That's why i looked around for one . Just ring a few transmission places and ask for a box . they generally have fairly new one's they import ,not old crappy ones . check out the picture i mentioned in earlier post ,it shows the different shifter positions.
