PK numbers

nope. not yet for the electric connection for lockup, that was still a few years off. All mechanical and controlled by a hydraulic valve, an "add on" small aux VB piggybacked onto the main VB "on topside". but I have yet to open this trans up for any reason, to see that. Thanks.
crap. it is a lockup. that means the converter I was considering buying won't work. there is a different spline count (by a total of 1 measly spline) between a non lockup and a lockup trans, on the input shaft. thanks for the info. does the list say what stall the converter would be that came within this trans (low or high stall)

OK next to that PK number were 2 additional groups of 4 numbers. After the PK4058384, that is followed by 8720 (space) 7883. any significance to that?
