The valve body I modified was a 1971 w/ part throttle KD to be used in a 1974 trans that we rebuilt. When I went to mod the VB, we found the seperator plate had some rust & pits in it from water that entered the case. I also discovered a few of the Transgo mods were performed, so we decided it was best to not use the 74 VB and to start fresh w/ the 71 VB.

Per the instructions for high stall convertor, street/strip, & firmest shift, I opened up A, C, D to .187" L looked like it was already opened up by someone to .187" I never thought to check the case for an orifice, but I suspect there was one.
B was left alone and I removed the .125" bearing.

Looks like I definitely need to install the .140 plug minimum.
