For those of you with difficulty sorting out my post - my statement was " there were no changes in ring spacing on WIDE BUSHING PUMPS".

I didn't say there were no change between the narrow and wide pump supports.

As for assembling - I said not suggested. I have seen instances where a guy installed a narrow bushing in a wide bushing drum. It will assemble -

Op - if you are having an issue determining fluid level - get a drain pan under the trans under the dipstick tube area. Remove the bolts holding the tube in. Warm the trans up and run through the gears. Shut engine off and pull the tube out and let it drain until it stops. Reinstall the tube and qualify the stick.

That's ALL the fluid you need. You still have a leak you have issues requiring leak testing.
