I can see how that was pretty embarrassing for ya. If it's any consolation, we've all been there at one point or another.
My most embarrassing moment happened when I was pulling out of a 50's style drive thru in Cleveland called "Anabels" in my Viper one night. The place was totally packed (as it usually is most weekends) and it was one of those situations where EVERYBODY was looking at me thinking I was going to do a big smokey burn out. Well not knowing if the cops were around or not, I just pulled out real slow and short shifted it. Trouble is, my "skip shift" kicked in, and put me directly into 4th. not where I wanted to be. Now the easiest thing to do when that happens is to not try and fight it, and simply let the shifter go where it wants to, then simply put into 3rd. then 2nd. But no...
I have to try and muscle it, and all you hear is this grinding sound, and moments later, the laughter. My wife looks over at me and says, "I can't believe you just did that." I looked back at her and says "I can't either".
Needless to say, the "skip shift" was unplugged that weekend.
