Good afternoon,
I started installing new bushings and see the pump housing bushing has a notch.  I lined it up with a hole behind the seal, but I see pictures of them installed with the notch facing the rear and left of center. Is that correct?   I do not see any hole in the rear for that to line up with.

Also see the rear stator support bushing has a notch, but do not see what that is supposed to line up with.  Can you explain which way it goes?
Please let me know.

Thank you,
Scooter

The pump bush notch goes to the rear of the trans inline with the converter feed hole. I'll have to double check but i don't think the stator support bush matters

Thank you for the reply,
I have not found any holes in the bore to line it up with except the one by the front seal.  Do you suppose there are different versions of pump housings? 

Regarding bushing notches, there are others that I have not found to line up with anything.  The only thing I did catch was to put the grooved bushing in the front of the case and the smooth one at the back of the case.
Please let me know.
Thank you,
Scooter

finally figured out how to add pictures

Correct the holes are not in the pump bore , look on the stator support , that's where the oil feed is . As in the pic above shows where the notch goes facing the rear of the pump.
Look below where the arrow is , there is 3 small feed holes . One to the left feeds the converter through the stator support 

 The hole in the front is only a drain, nothing lines up with that

Thank you for the reply,
I have added an image of where I installed it.  The notch is at the red mark I put.  Hope that is correct.  Also Loctite.
Please let me know.
Thank you,

Thank you for your persistence.
Now that it is in, I see that it is probably based on the orientation of the spiral groove to get best lubrication.
Tranny is mostly together and maybe done today.  Will update.
Thank you,

If you look at the face of the stator support when it is bolted to the pump, the feed hole for the converter lines up with the lube notch + groove

Make sure the return hole behind the seal is not covered.

Good morning,
I believe we have a successful rebuild.  Drove it around yesterday, adjusted the shift a little later, pressures test good and found no leaks. I downshifts proper.  I think it is working fine, we will see after time.
Thank you all very much for your willingness to share knowledge and time. I appreciate it very much.  Now I can share what I have learned.

Ever wonder how frustrated a person can get when I remembered after the transmission was installed, but not connected or filled with oil yet that I have to pull the valve body because I left out the check balls and springs?   Well, at least I remembered before it was too late.  I had set them aside in mark bags to not loose them.
Thank you,
Scooter
