Ok, I dont know what to think. I put the tranny in the Burb and put a new filter on it with a pan gasket. Filled pan and started the engine. Kept adding fluid until it read full on the dip stick. I went around and put it in neutral. Slid it into reverse and nothing. Put it into drive and still nothing. IDK if I posted my problems here but on DTR I was told I could have shredded the front hydro pump. Well that was about 2 months ago. So I dropped the pan last week and found nothing in the pan in the way of metal. Lots of fluid but no metal. So I was thinking back a little. When I first put the tranny in and before I added the driveshaft, I ran the engine and shifted the tranny into D. The tailshaft spun and I went to put it into park and it wouldn't go, just made a grinding noise. No, I didn't think about it when I heard it, I shut the engine off right away. That is when I thought about there being no resistance to stop the internals. Anyhoot, I added the driveshaft and now it wont suck up fluid nor will it turn the driveshaft. What is going on???

Still the same problem. Sounds like you took the ears off the pump.

You would not find parts in the pan eather. Where the ears would go is inside the converter. Your need to drop the trans and check to see if the pump ears are sheared off.

i was thinking the same thing, after an incredibly insightful teardown of a 518 at SOP.

when things like this happen, it makes me like manuals even more.

My money's on sheared drive tangs, you could try a oil pressure gauge in the line pressure port and see if your making any pressure in drive.
