I think I killed my DTT 47RE

She hurt. Dumps the direct clutch above 160°F
Im guessing I rolled a seal and it finally gave up.

Well atleast your learning. You never learn anything the easy way. What I'm learning from this is that I guy lucky on my rebuild lol. Be interested to see what you find
 
I just hope the steel is from me being a dick and not flushing the coolers. May not matter now with how much has gone through the trans

I'm not sure the best way to effectively flush the coolers without an actual hot flush machine like firepunk has. I ran all new coolers and lines when I built mine because I converted my truck from a nv4500, so I lucked out.
 
Buy new coolers. If you don't have a way to hot flush it, the cooler will never expand to let all the debris out no matter how hard you try.
 
And? Radiator isn't THAT expensive, did the same thing to mine. Was just as cheap as paying someone to flush it
 
Well, it wasn't cross contamination.
The day I was trying to sort out the different in the thrust bushings, I sat it on the input shaft that already had the forward clutch assembled. I think I assembled the gear train and came back to it. I never moved the plastic bushing. I knew where it went, I just screwed up.

The end play checked OK. I knew something was up because of how difficult it was to rotate the input, but I talked myself into believing it was just the new assembly. It wasn't. The pump was shoved into the bushing in the drum. That's the source of material. The clutches didn't frag out, but 2nd gear band it cooked. I can't tell if it's an unrelated failure, or a result of the head from the drum trying to weld to the pump assembly.

So, what's up with only the two clutches and friction nearest the piston showing the majority of the heat? The drum had some wear on it from the steels, but nowhere near enough to hold one engaged imo.

What do you mean, did the same thing to yours?

Yes, just dropped a whole radiator in. I tried to back flush it multiple times before I gave in, now wish I'd bought new from the start.
 
Ordered the big iron to fix it with. Tearing the gear stack out to see what thrusts are hurt.

I got parts in finally. I did some digging and found a shim kit that will let me use my planets once they are cleaned up at the machine shop. I was hoping to have them back today, but that didn't happen. I picked up a planetary group from WIT used, but want to run the new parts if I can. If I can't get them to stack with the right end play, I guess I'll shove the used parts in it.

No but I will. I'm still waiting on getting my planetaries back from machining. I got my drum in, tore it down this morning. Drilled it and added the feed port like I did the original.

So.... In the course of building this thing the less-than-correct way, I damaged the planetary groups by not having thrusts where they belonged. I didn't take pictures of the damage, but I took a Pic of the parts now that they are back. I had the machine shop keep track of the material removed for me to use as a baseline for my shim pack. The shims go between the carrier and the thrust bearing in order to get the end play within spec.

These don't fit six pinion planetaries. As the label would imply.
Getting to old for the DIY lyfe.
