Had this tranny rebuilt a while back, maybe 9or 10 months ago. The guy does a 12 month warranty. Got the tranny installed, filled and TV cable adjusted. Took her for a 20-30 minute drive and everything seemed fine. A day or 2 later took her to the dump and lost reverse. Forward gears catch but are noisy after about 5-10 mph. The guy asked about my transfer case, The fluid level and color and asked me to drop the pan and check for debris. Had to get it towed home. It seemed like the transfer was binding a little so i pulled it and ordered a rebuild kit. Checked the tranny fluid and it was pink and at the correct level. I got caught up in some other projects and just now got around to pulling the pan. I found copper or brass washer looking material about 3/4" inside diameter and some steel pieces as well. This tranny has less than a hundred miles on the "rebuild". Any ideas or opinions on my tranny situation would be appreciated. Thanks all.

Sounds like you need to tow it back to the guy who rebuilt it. Ask him if he rebuilt it or remanufactured it. A rebuilt only gets what parts are bad and reuse the other parts. A remanufactured gets all new parts and updates.

The gold colored material you found in your pan is brass & is critical. A small amount of gray powdery material would indicate some clutch wear & is acceptable after 10-20 K miles, but brass is hard part failure. I had a 700R4 that made the same noise you described & I traced it to low fluid pressure. The pump was good, but a servo valve seal was dumping the pressure & caused catastrophic failure. It's too late to check pressure on this trans now, but when your mech rebuilds it, get a 0 to 175 psi fluid guage & check the press (the test port is on the left side of the case) before you put too many miles on it. If it's not showing 125 psi + or - 15 psi depending on fluid temp, take it back because it will be prone to failure like this one.
K, not a Ducks fan but I follow civil war games. I'm from Texas so...."Hook em Horns". Anyway, a fellow by the name of Brad in NE Portland did my tranny. He charged me $550 and I got an HD TC out of it too. He emailed me back today and wants to tear it apart and fix it ASAP. He knows it's a hard part too. Of course he had that always ridiculous request for the reciept, LOL. Anyway, I'm gonna make an attempt to insert the images. Wish me luck.

Holy crap!!! I can't believe whats in the bottom of your pan. Some important part went bad big time. Good luck. At least it sounds like he's going to take care of it.

I'm not sure but those 2 copper halves look like the remains of a thrust washer from one of the clutch hubs. Maybe it was assembled too tight, not enough clearance, & burnt up & broke in half. After it fell out then there was too much clearance & it's all downhill from there. Is he going to warranty it?
I was definitely a Longhorns fan in 05? when they beat USC for the Nat title lol. I was probably the only one on the west coast

Roll Tide & War Eagle! We have a divided house here.LOL.
LOL, always like to see a thread reply that starts with "Holy crap!!'. Ha, yeah that final Texas drive was just enough. I work with a USC guy so he caught a little crap over it. As far as I can tell, he's gonna be up and up with me. I installed the tranny so I hope he can't find a reason to blame it on me. I'm pretty sure I did a fair job of it. I'll let yall know when the full scope of it is known.

Well a trans install is pretty straight foreward so hopefully he won't try & lay the fault on you. The only 2 things I can think of that he might quiz you on are the TV cable adjustment & your procedure for filling the tc & the initial & secondary fluid fill. If you can quote those to him, there's nothing else he can blame you for.
So he pulled the tranny apart and the planetary was toast, the shaft on the whatever hub was actually visibly twisted. He blamed my cooler for the damage. He was square about it though. He went through her again and replaced the parts and wasn't planning on charging me. I gave him 50$ and I'm gonna give him a 4L60e core that's just sitting in the yard. When I pulled the lower cooling hose from the radiator there was alot of black debris like rough sand. Blew out the lines and bypassed the radiator all together with an auxilary cooler. Got it all put together and adjusted the TV. Tranny wise I think I'm good but now the brake light on the dash is on and the rear brakes are froze I believe. So, I'm headed to make another thread pertaining to brakes. Thanks all for the replies.

All that black debris was most likely clutch debris, he should have flushed that out when he did the rebuild.
He's like an hour away and I pulled and took the tranny to him. He initialally told me to be sure and clear the cooling lines before installing, and I did. The trouble is that had I let it sit for a while longer I would have found more crap settled in the bottom of the main cooler. That's why I bypassed it al together. Do yall think daisy chaining auxillary coolers is enough, too much?

Dual coolers are fine. I run 2 -12,000 GVW coolers on mine. The cooler you can keep a 700R4 the better, especially if you're going to be doing any towing. The black crap that came out of your cooler was obviously from his rebuild considering the amount of clutch material that was in your pan in the pics & the fact that you flushed it when you installed the trans the first time.
edit** Bypass your in radiator trans cooler if you haven't already.
