4L80E Harsh shifting from 1st to 2nd

Need to look at the pickups or tone wheel to see if the signal source could be swapped ie the cps would need half
as many
Just brain storming here... most distributor pickups for a v8 gasser have 8 lobes, one for each cylinder to send signal to fire the coil plus give rpm signal to a tach. iirc though I might me totally wrong here, doesn't the 6.5 tone wheel on the snout of the crank have 4 lobes for the CPS? maybe, just maybe the oil pump drive cam sensor was build the same as the gasser distributor pickup coil. I was never able to get any kind of signal from the oil pump drive sensor on mine plus it was puking oil from the connector. not sure if it's a candidate to be dissected.
