833 making odd noise in 2nd gear only

When you reinstall the trans, hopefully finding your problem, get a couple of 7/16" bolts like the 4 that hold it in, only longer, say 2 "'s. or so. Cut the heads off of them. Screw them into the 2 bottom holes of the bellhousing. This will help guide the trans input shaft through the clutch disc. Also, your arms get tired, they will support the trans while you take a rest. You have to pull it and maybe the clutch too, something is wrong, and there's only one way to find out. Time to get your hands dirty.
