FWIW, I replaced the synchro rings in a TKO600 with no prior experience working on a manual trans but do have ample experience turning wrenches. After taking the trans down, and becoming acquainted with the components, the actual replacement of the parts was pretty fast - take note of the orientation of the synchro retention springs. On reassembly, clean gasket surfaces really well and use a good sealer - Ultra Gray or an anaerobic sealer. If Ultra Gray - let it cure for a long time. FWIW, I didn't need snap ring pliers when I did mine. The below rebuild video is fantastic.
