Performance 700r4 rebuild
Did some assembly Sonnax reaction shaft, OEM 5 pinion planet from 4l65E. I initially planned to reuse the reaction shaft from the 65E, but it was too worn where it meshes with the ring gear. New 29 element Borg Warner sprag, and Sonnax heavy duty overrun hub- Wumbo

Performance 700r4 rebuild
Thanks Nick I started assembly on the input drum last week, installed new bonded pistons and Transgo 7-CS return springs and orifice. Forward clutch clearance was only .005, so I had to order a thinner apply plate. It showed up today, so I had to install it. Forward clearance is .035 now...- Wumbo

Performance 700r4 rebuild
It had the usual 3/4 slip. So I thought being a performance trans, I'll just tear it down, clean it up, slap new frictions and steels in it, and send it. Probably got some trick parts in it, being a $4K racing trans, right?- Wumbo

Performance 700r4 rebuild
Time to rebuild a "performance" 700r4. It's a Hughes Performance 74-1 as best as I can tell.- Wumbo

700r4 speedo port not spinning at all.
It can be either. Install an electric VSS if you want to go that route, or you can remove the reluctor, install a mechanical drive gear and driven gear, and run a mechanical speedometer.- Wumbo

Thats a reluctor for an electronic VSS. You need to replace that with a mechanical speedo drive gear. Look at the grey gear: You will also need the metal clip that holds the mechanical drive gear in place.- Wumbo
