Since the method MOPAR posted on the fill tube level stick, start engine in park, shift into drive then place in Neural and check level, which was supposed to purge converter and set running fluid level was standard, this would be the simplest way to deal with the issue. I know how I dealt with it years ago. I was always cooking my transmissions or breaking tail housings or something. When I found out about the NO YO YO kit I started installing them in every transmission I worked on, TQF's that is. I've been out of the repair business on those trans for years now so I can't tell you anything about the Land Rover.
