The Trans Am I just picked up had the gears swapped from 2.73 to 3.42

The speedometer is quite a bit off, so I bought a SLP speedo calibrator from a member here.

The only instructions I have been able to find are these:

The dip switches on this don't match mine, I believe those are for the 63007 for the lt1 cars.

Does anyone have the instructions for this one?

Thanks,

I would only use that on a M6 car, not an auto. Your shift tables and converter lock up tables will still be calibrated for the 2.73 gears. Find someone with tuning software to make the change and it will rescale all the tables for the different gear ratio. It makes a huge difference.

Thanks for the advice. It is an auto. I have been looking around trying to find someone local that can do it with no luck. Maybe I just need to find a used Hypertech for now.

I am also wondering if this is throwing off my traction control. It seems to go on at times that don't make any sense.
