Shifting to 2nd grinds.?

[A//// Guy]

You need alot of special tools, pullers for the bearings and gears. I wouldnt attempt it, I did and didnt have the right tools so I ended up giving it to Mitsu and overpaying. If your going to spend over 500 for a rebuild, either by yourself or from someone else, I would have it professionally built by TRE or another shop.

Either live with the grinding, and try some other fluids- synchroshift, redline etc. Or find another tranny in better shape or have 2nd gear synchro replaced- There are more parts that will be worn when you take it all apart, so you wont just be replacing 1 thing.
