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

Oddittitties in the pump. PR valve. No TV or reverse boost. Just the valve, spring, and aluminum plug. Edit- 4L60E boost assembly sleeve. Flats ground on the TCC valve- 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
