DRAC calibration question

[fun4me]

I have a 94 ecsb. I recently replaced the gears. Of course the speedometer was waaaay off. Went from 3:42 to 4:10. The transmisson also started shifting too soon. If I do the DRAC calibration will this also change the shift points on the trans?

It will. The computer gets its speed input from the DRAC also.

Thank you. I was starting to think everyone had gone FSC forum.
