We had to take out my 4L60E transmission to fix a freeze plug. We put the transmission back on and now it will not do anything in any gear, it physically moves to the gear and does not engage. When we put it back up the torque coverter was not seated, we then turned it, it dropped down. We then put the trans back into place. Fluid is full, everything is connected, I'm at a loss.

Sounds like you broke the pump when you were bolting up the trans and the converter was not fully seated in

Are they that fragile. I mean to the point I wouldn't feel like it broke or anything should have broke

Big question- did you pull the tranny to the block BY HAND, and then the flexplate and torque converter were still a bit apart from one another- or did you pull the tranny to the block by tightening up the bolts, and the TC was tight against the flexplate?

I think you know why I'm asking...

I was tighning the bolts, then I noticed there was no way it was going to tighten up because the converter wasn't all the way in. Then I pulled back rotated the converter it dropped into the trany, and then of course it bolted up no problem. I think I know why you asked.

Yeah, because the tranny's pump will get damaged if the converter isn't in place and the bolts are tightened down to bring the two together. That's why it is always my habit to make the tranny bellhouse meet the block- by hand- before I start tightening any bolts.

I use long studs (3/8 NC bolts w/the heads cut off) to locate the tranny in 4 places, so it will slide up easily. Usually takes moving the jack up and down as the tranny is slid up to the block, but it's well worth the little bit of extra effort to do it that way- for me, at least.

It takes some amount of force to damage the pump, but if the bolts were tightened down any at all against the incorrectly installed TC, the damage could occur. How much force, I don't know- so far, I've not fragged one this way.
