Default Replaced transmission, now truck wont shift into gear

Hey all,

My trans bit the dust about a week ago. After calling around to a few shops and getting quotes on rebuilds, I decided to go the junkyard route. For $350 I got a trans with 60,000 miles on it that has been inspected and "tested", and comes with a 30 day warranty. I dropped my old one with some minor difficulties, and this morning finished putting the used one in. Used transmission came with a torque converter, so that is "new" too. I re-filled the trans with oil, let it idle for about 10 min, then tried to shift into gear. Nothing happened. When shifting back to park, there is a grinding noise, similar to when someone grinds a clutch. I checked the lever on the trans while someone else was shifting through PND21, that seems operational.

I was reading through the DIY about installing a torque converter, and I noticed it said you have to seat the torque converter on two sets of splines. I THINK i did that, but am not sure. I didn't have any real issues bolting the torque converter back onto the fly wheel, wouldn't there be clearance problems if the torque converter isn't seated right?

If i did seat the torque converter wrong, is it toast now? Do these symptoms sound familiar to anyone? Would that have fried anything else in the tranny?

Could it be a fluid issue? I unhooked the return line to flush out all the old fluid, and started refilling once I saw bright clear red fluid coming out of it. Initially, when unhooked, there wasn't a lot of fluid coming out of the return line, after 10-15 seconds, fluid started flowing at what I would consider a "normal" rate. Is it possible fluids not getting everywhere it needs to? What about the torque converter? I didn't top it off before install, there was already fluid in it. Doesn't it cycle through with the rest of the trans fluid?

I know this is a long list of questions, if there is any other info that I can provide that would help someone diagnose my problem, just let me know and I will add it.

Thanks all.

Did you check the level on the dipstick....?

Might not be enough fluid in there to activate the solenoid to put it into gear....

Reading some more, really starting to seem like I somehow didn't get the tq converter seated correctly. Can anyone tell me if I would have been able to assemble the tq converter to the flywheel if was not seated properly?
