I had to do something, lol. I didn't want it to look like a Hughes trans anymore, so it got the finest paint on the rattle can shelf.- Wumbo

Performance 700r4 rebuild
Bought a rebuilt pump from ebay. Met expectations (they weren't that high). New rings, seals, and bushings. Used rotor, vanes, and (7 vane) slide. Teflon coated bushing is good Pump body and cover had some wear. Would have been ok in a stock build I'm sure, but I took them to the lathe and...- Wumbo

Anyone know if TCI marks their constant pressure valve bodies in any way? They use the same pressure regulator setup as what I had in this pump.- Wumbo

Resurfaced pump, pressed out stator support, and checked pump clearance. Pump rotor and slide came in at .0018 after machining the pump. Waiting for new Sonnax stator support to show up.- Wumbo

Performance 700r4 rebuild
Checked pump clearances. New rotor .015, new slide less than .015. Surface finish on both sides is ugly. Somebody resurfaced them on a mill with a worn out cutter. I'll be chucking them up in the lathe to get a better surface finish, and get clearances in spec. Drainback circuit was wonky...- Wumbo

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
