It is a Dataquest by altronics.

There is no shifting. pulling off the line in 3rd (dirrect). The differentials are REALLY low gearing. Usually have a final gear ratio of 21-1 to around 23-1



Since your reading a data logger what does it say it
is at about 5000 rpm... if its a 2800 stall or so
it should show about the same.... to be honest I've
never seen (or heard of) 2% slippage... unless some
numbers are wrong..... I have a driveshaft sensor
so it is a direct relation to the engine rpm... the
engine rpm is X and the driveshaft is X = the conv
slippage
