Torque Converter Alignment, forced together engine and tranny, Help!!!
Hi guys! This is my first post and I need your help? I just installed my reman ATK 4.0 in a 99 Cherokee. From reading other posts it sounds like I dont have the torque converter seated properly as it only moved back twice when I put it on. I drew the engine and tranny together with the bell housing bolts and I went to align my torque converter to flywheel bolts by turning the crank at the damper but the crank wont turn. I know I need to take the engine back out and seat the torque converter properly, but what I am worried about is if I caused any damage. Has any of you done this before or know anyone who has. What should I do, is there anything in particular I need to look for or replace? Any help you guys can provide will be greatly appreciated. Thanks!

Not sure NOW but you should as you put it onto the splines of the tranny ( converter hub is lubed with tranny fluid) be spinning and pushing the converter back--you should feel 2-3 drops as it gets into the sun-gears of the pump and the pump splines find and mess with the converter.
The converter should be well inside the bellhousing. When the tranny is bolted to the back of the motor you should be able to spin the converter freely or freely enough --if not and when tightened to the motor its BINDING it probably didn't seat all the way. You can TRY backing out the bell bolts and pry it away some til you can spin the converter and see if it does drop back.
Usually again you bring 1 hole from the flywheel to the bottom and spin the converter to match it then push the whole thing around til the next whole. I can't remember if the Chrysler only bolts to 1 pattern or not ( meaning you only have 1 way the bolts will all line up correctly). In these cases when coming apart we would leave a punch mark on the converter - and a scratch on the flywheen to align the first time.

If you bolted it up. The trans should find 2 dowel alignment pins on the back of the motor ( sometimes 1 or both are missing due to them coming off on a previous install). When pushed on these pins and maybe 1 or 2 bolts tightened the converter should remain free.
If indeed the pump was not all the way back and you tightened all the bellhousing bolts you would be forcing the converter hub into the pump SUN gears. The hub is hard the bushing is not and the gears could get burrs or actual dents on them depending how much this was forced.
If something isn't going as smooth as it should there is usually a reason.
Not saying this happened. To make sure your gonna have to re-drop the unit. Pull the converter out and check the hub and inside the pump. I have put many in that wouldn't drop all the way due to the fact that the pump was NOT align perfectly straight.
Man my typing bites today.
Ask some more you shall recieve

Also there are 2 types of converters out there -ones with "flats" on the hub and those that have 2-180 dgreee cut outs about 1/4-1/2" deep.
These MUST sit way into the pump locking it into the pump gears.
You would usually apply trans fluid to the hub -gently put it in past the seal and turn and push while slowly spinning the converter until you can see and hear it fall back in and lock-sometimes it falls in "in steps" until its all the way back. I have had many that I had to remove and spin and spin and push. Sometimes getting another guy because it seemed it wasn't going in all the way.--The pumps are 2piece and when taken apart for a new bushing when put back together they are not perfect- not allowing the converter while passing through the bushing to line up.
We would remove the pump again -loosen the bolts and realign it-- put it back in the case-tighten the those bolts and try again.
