I highly recommend if any of you want to rebuild your trans, go watch all of Nicks videos on whatever it is you’re building. His videos are excellent. Nicks YouTube channel- Wumbo

Performance 700r4 rebuild
Yes, I blocked 4th accumulator. 1-2 accumulator Im using a Sonnax pinless, and haven't commited to what spring to use. The springs that were in the 1-2 accumulator were white (outer) and purple (inner) I believe, but too large a diameter to use with the pinless piston, and extremely stiff. I...- Wumbo

Performance 700r4 rebuild
Busy week, but got back into it. Finished the pump. Pump clearance was .0011 on slide and rotor. It did have a .500 boost valve, but I replaced it with a Sonnax o-ringed .500 boost valve and reverse boost valve. Also installed Sonnax TCC valve with teflon sealing ring. Failed to take pictures...- 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
