Poor Shifting? Seek The Dealer For Trans Mount Failure!
I felt a need to post this to those who keep missing the 2-3 shift or even the 1-2.
BEWARE!!!
This is a sign that your trans mount may be the old one, the one that lets the motor fall out. Here's how I know:
Most of you probably have seen my thread regarding how mine fell out, and the NHTSA case going on. BEFORE the incident occured, I would constantly miss the 2-3 shift under hard driving, and occasionally miss the 1-2, especially if I was launching quickly. I just thought it was a case of me not mastering the car, or a case of cable-shifter blues.
However, after the incident, and after Mazda made it right (by replacing everything that was damaged when it happened, and upgrading the mount), the shifting action has improved to a whole new level. It was as if I am driving a totally different, much more capable vehicle. I haven't missed a shift yet, and I've actually done some pretty agressive things just to verify the engine wasn't going to fall out again. I'll occasionally get a BANG when I accelerate over rough pavement, which indicates a wheel hop incident and the subsequent bottoming of the soft rubber mounts (not the trans mount.)
Bottom line is this - If you are missing shifts regularly, I propose that it is not necessarily the shifter (though it is a possibility), I recommend you immediately visit the dealership and see if the trans mount is loose, and in danger of breaking like so many other have. DO NOT DELAY on this, because it can really ruin your day, and it can kill. When an engine falls out at 80mph, and the driveshafts dislocate and flail at those speeds, you can imagine what happens. I know what 30mph did.
Cliff notes version (I'm long winded and passionate, apologies):
If you are missing shifts, go check your production date on the driver's outer door jam. If it shows an '06 or very early '07, then you'd want to RUSH to the dealer (or better yet, call Mazda Customer Care AKA Roadside Assistance to pick the car up, and get it inspected), and let them know you are very concerned about this potentially deadly condition. How this is not a recall yet, I have no idea. FLOORMATS get recalled, an engine falling out of the car, gets a technical note (not even a TSB).
