[SD987]

This is not common to manuals and is defective and specific to certain 05 987s with the 5-speed.

I know the exact lock-out phenomenon (neutral-first) you're talking about and have commented on it previously. The problem manifests itself in certain instances of the new Japanese manual tranny in the 05s.

There is a TSB out on this, where the dealer replaces the shift template but from what I've read, this doesn't always fix the defect.

From what I've been able to determine, the tranny doesn't like the way you're working the clutch/gas pedal (franky, you're shifting sloppily) and proceeds to lock you out, the next time you shift neutral-first. I rarely have this problem anymore as I concentrate more on my technique, but if you're sloppy it will repeatedly lock you out.

I'm preparing a more specific technique post to follow-up my previous post from awhile back, but in the interim you might find some relief by going:

Shifter from neutral-first, then push clutch in, then push into first...instead of
Push clutch in, move shifter-first-into first as one move

Additionally:

When you're pushing into first, go towards your knee, just like Pop taught ya, instead of vaguely in the direction of first.

Like I said, there's more to fixing it than that...more details to follow.
