I still see folks with OBDII rigs asking for gears.
Can't the Dealer just reprogram the PCM?

Speedo gears can be had new for around $50 shipped, and it takes a few minutes to remove, index, and replace them. I don't see the point in fooling with the PCM, and I don't understand why guys don't just buy new gears and be done with it. Maybe some gears are particularly rare? I just looked up the part number, and bought one online.
No offense Guys...
The nature of my question was purely knowledge based, and didn't have anything to do with how inexpensive it would be to either ignore the problem, or swap gears.
My question was based on the knowledge that all OBD2 models are not cable driven, but have a tach at the speedo gear. There is an aftermarket correction box available, but I was wondering if any folks with experience have seen a programing solution?
Whitexj99-You came the closest to understanding the question, and I'm not discounting it, just was hoping someone who works for a Dealer has approached the problem from a different direction

The 96-04 PCM can not be edited to correct for tire/gear changes. Nor can aftermarket plug into the OBDII Port electronics correct for it. The Chryco PCM is rather primitive in most respects. The GM ECM of the same vintages can be edited for nearly anything... Which is one reason the Custom Car folks go with them.
