My question is this: Repair the installed tranny to include all new syncros and cones and deal with the down time. OR, tear down the spare tranny and inspect for problems (bad bearings, worn gears, etc) and replace the syncros and cones like I am planning to do anyway.
I have a factory repair manual for this job. I am not very familiar with this job. I KNOW what is wrong with the installed tranny. I can spot a bad bearing but may not be able to tell a worn gear from a good one or know that a shifter fork is tweaked. How hard is it to inspect and find bad parts?
Opinions on my best course of action?
