When you install it, it has you trip the solenoid to disengage the column locking mechanism. From that point on, it prevents the lock from engaging in the first place. I've had it installed for 3 years with no problems. No "pull key..." crap. Nothing. Works like a charm. AlRalphP said:So what exactly does it do? I have not responded to the recall notices because I am NOT taking my car the the dealer wrecking crew and I don't want to hassle with losing my tune.
Thanks Al: So there is then, no column lock, ever? Do we not consider that to be any sort of a security risk?aclar said:When you install it, it has you trip the solenoid to disengage the column locking mechanism.

I hear you Al: And, I guess the only thing my column lock on my '83 Z28 accomplished was to create more things to fix after they broke in and busted it all with a hammer so they could start and drive it. :bmad:aclar said:Nope - no lock at all. I suppose it could be looked at as a security risk but, in reality, if someone's going to steal the thing, they'll find a way - column lock or not. Column lock won't stop someone from grabbing it with a flatbed which has been known to happen. Of course, I shouldn't talk - mine never leaves my sight... Cheers - Al

The problem is that some have suggested the lock motor in it's now-permanent unenergized state can still move (mechanical shock and vibration), and with time may "creep" back to the locked position.
Bad for you if it happens when you're going through a ramp at 75MPH.
Better solution, more work. Provided you have a Dealer that'll help you, buy the kit used for the CLB recall on Automatics. For Automatic transmission C5s they remove the steering wheel and replace the pawl (the thing that engages with the latch when the latch is driven to the locked state by the lock motor) with one that doesn't have the feature to engage the latch. The motor still does it's "in and out" thing when you turn the key, but it doesn't latch with anything so the wheel is guaranteed to always stay unlocked.
If I understand correctly, the 6-speed recall only includes reprogramming the PCM. It adds additional checks designed to prevent false locking or unlocking, but the PCM is still capable of performing either.
One thing I've learned in my years in engineering, nothing in software and electronics is 100% foolproof. Given enough time or enough units in simultaneous operation, failure modes are always exposed.
The Manual's software-only solution is still imperfect and capable of failure compared to the Automatic's robust, mechanical-only solution.
