Well, since this thread is being revisited...
Yep, replaced many a first gear in the Xterra transmissions. Fronty's too.
No rhyme or reason, just goes. Curious thing though, haven't done one yet in an off-roader's vehicle. They've all, and I mean all have been in regular mall crawler vehicles. Don't know the significance of that, but it's an interesting fact.
Keep in mind for prices this little factoid.
Dealerships don't all charge the same hourly rate as others. We are now at $110 per hour, but others in small towns only charge something like $60 per hour, or whatever their market will bear. Get it?
So what seems outrageous for some, is actually good for others. Need to remember that when saying "That's unreal!" to someone in a big city, from a small town.
