In any case, it's machined into the output shaft, so there is no way to correct it with a gear change. 23 is as far as available gears go, and the math tells me I need 24. I could reduce my error with a 23, but I'm told they don't hold up.

Ran into a problem when I rebuilt my dash using Autometer gauges. Couldn't get my speedometer to read right. Went through the calibration procedure at least a dozen times. Replaced the VSS and used a Steeda 23T gear. Ran out of patience. Finally ended up installing the Autometer GPS for the speedometer- end of problem.

I varried my speedo by 11% by getting real tires. 275/60/r15. Easy overdrive adder mod.

My AOD has the 8 tooth output shaft. I've been running a 23 tooth driven gear for years without issue (the black one Late Model Restoration sells). I plan on swapping a 21 tooth back in and running the FRPP speedometer correction box at some point, but it hasn't been high on my list of things to do as of yet.
