Shaft rpm from vss

[nathaninwa]

My goal here is to calcualte converter slip. Have my 4l80e last year all this stuff was built in. Can we calculate shaft rpm from rear vss? I have a 16 tooth sprocket on my pinion with a hall sensor

Or maybe I can split the signal and use an input on my I/O box and have it a specific shaft speed input?

I think there's already an option to do this.
