So, Greg, have you serviced the AISIN yet? Just bumping your original thread here...good information.
Cross-referencing some info from this thread https://www.cumminsforum.com/forum/20...nance-day.html
into this thread...........
On to the fun stuff.......gaining access to the four Aisin transmission pan bolts closest to the transmission crossmember.
My initial attempt was to use a 1/4" drive nut driver, a universal joint, and a 10 mm socket. FAIL !!! I could not get any combination of the above into the area where the four most rearward bolts were located.
My next attempt was to remove the three nuts that attach the transmission mount to the crossmember, then, using a floorjack, raise it slightly in hopes of gaining enough access to the bolts. FAIL once again....
Upon investigating further.....there was only one last alternative.
Drop the crossmember!!!!
For those of you with the Snow Plow Prep Group or Protection Group, you'll need to remove the transfer case skidplate. Remove the three nuts holding the transmission mount to the crossmember.
Place a floorjack under the transfer case.
On the driver's side crossmember, remove the innermost bolt that attaches the crossmember to the frame. Loosen the outermost bolt a few turns so as to allow the crossmember to pivot.
Better view of the bolt to be removed....
Moving to the passenger side, remove BOTH bolts securing the crossmember to the frame.
It will be a chore, so be prepared to pry downward on the crossmember to get it down enough.
You now have access to the transmission pan bolts !!!

Note the four small pan magnets.

After cleaning the pan and pan magnets, I used a little shot of this to keep the pan gasket in place while I re-installed the pan.
My driveway has a slight incline to it, so I level the truck up for best draining.
I wish the drain plug was down lower into the pan, as there's a decent amount of residual fluid, even when drained via the drain plug.
I had eight quarts of ASRC fluid at home, as I anticipated I would not lose much more than an extra quart when I dropped the pan. I was quite surprised to find that there's more retained in the pan that does not come out the drain hole than I expected, coupled with a decent amount that floods out when the filter is dropped.
I installed 7 quarts, took a shower, and got ready to meet my wife in Richmond, KY for a dinner date at O'Charley's. Since I was too nasty to test drive the truck after the servicing, I decided I'd clean up, then get the truck to operating temp, then re-check the fluid.
More fun begins.....while I was brushing my teeth, I decided I'd run outside and start the truck. I came back outside, only to find the CEL on.
I decided I left something loose in regards to the CCV filter, so I'd check it when I got back.
I drop the truck into reverse......and there was a huge BAMMMMMMM just like someone rear-ended me at about 3--5 mph.
I decide to turn the truck off, pull the code, and found I had a P0868---Transmission Fluid Pressure Low. The BAMMMMMM also happened when shifting into drive.....and back & forth.
I think to myself......now this is great.....probably an issue with the seating of the new transmission sump filter...but I was sure I had it in good.
I cleared the code, and the problem vanished.
After driving about 18 miles, I was finally to operating temperature. I check the fluid, added 1/2 quart, and re-checked. I added the remaining 1/2 quart and drove on to Richmond. When I got back home, I re-checked and the level was only about 1/8" above the "COLD" mark. I'd bet that I'm a solid 1.5 to 2.0 quarts low as of right now.
