4r100 TC seating help

im replacing the TC in my excursion, 4r100 with 126k. I bought one form Racer X, the eagle 6 stud. i am trying to seat it, its dropped down but the hub is sticking out about a 16th past the transmission bell housing. Ive been pushing and turning on this for an hr and it wont go anymore or am I doing something wrong? i bolted it up once thinking that was just it, but it touches the flex plate as soon as the bell housing is drawn to the block.... I was told the hib should be about 1/4" below the edge of the bell housing and it shouldn't touch the flex plate

Did you put a straight edge across the bellhousing with the old TC in to compare to?

What's important is, once the engine & trans are mated, is that you can turn the TC free of the flexplate. If you can do that, then the TC is fully engaged into the pump. If not then you're not fully "in".

Do you have the old TC still? Can you compare the size of those engagement notches and length of the hub? (lay them both on their faces and measure the overall hight)

i could not turn it freely.
I have it, but its boxed up and the trans isnt dropped all the way, I just backed it up a bit to try and turn and push some more.

and yes, with a straight edge,
just barely not flush

I wouldn't worry about the input shaft. You're only 3/8ths of an inch or less out from seating as you describe. If this were the wrong spline on the input it would be out much farther I'd think (plus, the old TC would have a problem with it). This sounds like a problem with the new TC.

Look very carefully at the new ones Hub and compare it to the old one. I can't think it could be anything else...

i tried to measure the tolerances etc. it actually seems the old one in a hair taller, tho I dont know on what side it is. the only difference i see is on the old there is a shoulder at the bottom of the hub and then the weld, the new one looks liek the weld is right at the shoulder. The hub on the old one also has a beveled edge both inside and out and the new one just the outside... Ill try to take some pictures and post, but Im at my wits end..
