Default TEJ hex code

I just got my CS and pulled my hex. Was tooling around the site and I found this post in a sticky.

Ah, the famous TEJ hex code again, I completely overlooked that in the original post! Since the components in the transmissions don't change (at least not much), in a model year, I wonder why there is a need for all the various "strategies"? It simply doesn't make any sense to me.

I have a TEJ hex code. Is this something I should be concerned about?

Thanks
Jon

That was my prefix in my 06 hex and i never had any issues with the tranny.....a little hiccup with the a custom tune but that was easily fixed.....

The rxdg was a bigger pia for Bill

Thanks for the feedback. Is it normal to be in 4rd or 4th gear at 30mph prior to tuning?
