Mis diagnosed clutch problem

I think I mis diagnosed my clutch problem. It would appear that perhaps first gear is failing.

When starting off in 1st, it hitches like it's skipping a tooth and it makes a fairly loud noise.

When starting off in 2nd, it doesn't do this at all.

I'm going to get another opinion from a more experienced person. In the mean time, how hard is a transmission rebuild or a repair of 1st gear?

Would a salvage transmission be a better idea? I'm completely in the dark here.

The transmission has 197K on it. It's an M5OD.

trans work is not fun, but doable if your got some good mechanic skills and equipment. If your new to wrenching hit up a juk yard and look for a truck with your trans that has been hit and grab the trans.

you have a chped, or missing tooth. rebuild is not too hard, but not for the newbee. around here, there are trans shops that will rebuild a manual trans for $750, and give a 12 mth, 12,000 mile warrenty.

I have my doubts as to it jumping teeth or a missing tooth at all. It might be a worn and loose synchronizer.

Could you give anymore detail as to what it is doing and what it sounds like. There really isn't a whole lot in the trans that would cause the symptoms your describing.

It almost sound like it may be something in a u-joint or rear end, or a t-case if its 4x4

It doesn't do it when starting off in 2nd gear and doesn't do it at all through any of the other gears.

I figured it was the clutch initially as the clutch pedal has fallen part way to the floor.

The clutch master cylinder is full of fluid and the clutch engages fully and it shifts smooth with no grinding.
