What PID to log for converter slippage?

[WiseGuyZ06]

Is it GM.TCCSLIP??? or something else.... or a combo....

I just want to know how much my converter is slipping on the big-end...

thanks:notacrook:

That is supposed to be it, but keep an eye on TCCMODE so you know when it is not locked.

Or compare engine RPM with GM.TOS multiplied by current trans gear ratio.
