Trans connectors blocked.
Did you already install AN6 fittings into the trans?
If no, do you have the right ones?
I used one 90 degree and one 45 degree AN6 fitting.

I fear that if you used a a pipe thread fitting, it can really get stuck. You need 1/8" straight pipe AN adapters. Search ebay for "4l60e trans cooler fittings"; they are about $18 for two.
(Note: GM changed the thread type around 2007.)
Sorry, but I don't have pictures of the fittings on my trans, but I used AN-6 teflon lines. I used teflon lines not only to better handle high pressure and oil, but because they are also smaller.
i tried to get some #6 to 1/4-18 NPTS made up in a 90 deg swivel, but would have to order a ton-i have seen them in 1/4 NPT, but i dont like screwing that into a straight thread

It did have a pipe fitting in there, to make it compatible with factory lines running to the '68 Lemans radiator. my plan was to take them out and put 6-an fittings there with a pushlok fitting and call it a day.
You should know by now that expecting to just "call it a day" never happens.
