If you are having shifting problems in the shift with the greatest difference in gears, then maybe you are just low on transmission fluid. Did you replace all of the fluid? Did you replace the filter? What was the condition of the previous fluid?

Must be illuminating the CEL light, then. Try to get a diagnostic done to see if any codes are stored. Also, does it normalize after 2nd gear or have you not attempted to run through the gears yet? Low fluid symptoms 1st-2nd are a very hard shift (slam) to a non-shift shuddering condition, lessening dramatically with acceleration if it does shift to 2nd.

The free scanner at O'Reilly's should have a connector for that, but it will also require the power from the cigarette lighter which is also a part of the kit.
Did you check the fluid from your fill on a flat surface with the engine idling? The fluid has to fill the torque converter (much fluid) and the radiator (little fluid). Older transmissions require more friction when the fluid and filters weren't changed enough or the fluid was overheated.

5 quarts total in the system sounds low.
"Description: AW4 4-Speed Automatic
Type: ATF+4
Capacities: 3.5 Quarts / 3.3 Liters (Service Fill) 8.2 Quarts / 8 Liters (Overhaul Fill)" - https://www.morris4x4center.com/knowledge-base/jeep-cherokee-xj-fluid-capacities-type
I'll try to find a second source.

The Chilton's shows 17 pints which is 8.5 quarts. The older A.T.F. is what was made for it at the time. I have exchanged my old fluid with A.T.F. 4 without a problem. It is backwards compatible.
