Clutch slave cylinder repairing do they have a rebuild kit

What is your question?

Trouble with gears or won't go in gear the resovoir cylinder had 0 fluid and we put some to see if it would go in gear , it didn't it would grind after putting it in 4th gear once I pressed gas. Now will not go n gear.
