904 Transmission Stopped Going Into Gear

But if that trans was operated with No end play then the thrust washers should absolutely be FRIED. Is there any sign of no lube on the thrust washer faces or the hard parts they contacted? Was a part of the band friction stuck between the drums? If your book and measurements are correct, where did .072 thrust washers even come from? Your pump washer looked like it had a wear line on it. Measure worn thrust washers on their thinnest point; not across the entire surface. Possible that the output shaft selective was chosen and installed correctly but using worn front thrusts which you may have inadvertantly flipped over. I'd put some play-doh or plasti-gauge in the ext hsg and then bolt it down over the bearing and see if it smashes completely. The compressed pump gasket is .015. I'm wondering what if you put a .052 on the output shaft and a .062 between the drums (total .040 less); will the direct drum then go far enough back into the sun gear shell to match the how-to pic? You could assemble it with the thin thrust washers and it would work, but if there's something in the rear train that is incorrect; it will eat itself up. Like if the support bearing isn't really seated but then becomes seated, your clearances will open up and thrust washer tangs could fall out of the holes.
