if you do not seat the torque converter correctly you can destroy the trans oil pump, rendering it useles.
how to seat your torqueconverter
torque converter not seated.
--------------------------------------------------------------------------
Below is a picture of the first stopping point when sliding the torque converter into the transmission (assuming it had been completely removed). The first stopping point can vary a little bit, so don't be too concerned if yours stops in a slightly different spot.
As this picture shows, the torque converter is not fully seated yet, the flange which is roughly an inch away from the front mounting surface of the transmission:

From here, I make a "fishhook" with my pointer finger on one hand and suspend the tip of the torque converter in the "hook" to hold it's weight as if it were fully seated. This helps prevent the torque converter from binding when trying to seat it (makes seating easier). Then, I spin the torque converter clockwise a few times and then counter clock wise a few times to see if it will catch to get to the second stopping point (if a few spins don't do it, I do a few more. If it's still a no go, I pull the torque converter back out and put it back in in a different position). Here's a picture of the second stopping point (easliy confused for fully seated) :
STOP #2
'second stop' pic below, still not fully seated.
If you think the torque converter is fully seated (above photo) at the second stopping point, it's NOT! It needs to go another 1/4 to 1/2 inch.

To get the torque converter to fully seat, I spin in the opposite direction that just did that got it to seat in the 2nd stopping point. Then, when fully seated, it will look like this:
(notice how close the face of the TC bolt flange is compared to the engine mating face of the trans bell housing.)
