It's number 2, as per deilenberger's first post (the 2nd in the thread, as I recall).

Although I haven't had a chance to do the test again, I'm pretty sure I would find that nothing has changed, since I still have the same problem getting into 1st gear. However, I asked my specialist if they opened the clutch, and they said yes. In fact, as they explained it, it sounds like they looked at it pretty thoroughly. It's possible they are wrong, and I will ask the dealership to look at this. But suppose (a) the car continues to fail the clutch test, and (b) the dealship also sees nothing wrong with the clutch? Having drained the fluid, replaced the cylinders, replaced any worn bits sitting below the shift lever, replaced the transmission mounts, and having been told that the other things connecting the transmission to the car look fine, what are the remaining possibilities? Possibly the clutch looks fine but isn't? Or just the transmission itself, as in importrp's case?

(While I don't want to replace the transmission if I don't have to, it probably costs me nothing (the transmission and it's installation are both still under warranty), so while it might otherwise make sense to replace the clutch just to be sure it isn't the cause, for me it makes no sense to do so unless I believe it really is the most likely cause.)

Default Problem solved

So having checked and/or tried everything else, everyone who looked at the car agreed the transmission was the problem, and the transmission was replaced. The problem is now solved. The transmission still sucks, or course, but now it sucks the way the factory intended it to.

Yeah, you have to be very precise with the transmission. It definitely has a very stiff mechanical feel to it.

Default Re: Major problems shifting (6-MT)

So after ready every single post here, it still seems like an "unknown" but internal transmission issue? Can anybody confirm this is the case?
