I have checked the shift point, and clutch engagement points with tachometers. Nova makes one that is very accurate. It's mechanical. I have also used audio tachometers over the years. They are not as accurate as the nova mechanical tachometer.

The use of a tachometer over the years has let me know what 6000, to 50,000 sounds like. You can also look at the tach exactly when it engages.
