The 241 is a good case. The biggest issues occur when they are put into scenarios that they weren't intended, such as running them with no fluid, smashing them on the rocks while wheeling, and other types of obvious abuse. biggest thing is keep it full of fluid.
Sometimes the shift fork goes bad, which can make it difficult to get into different ranges, and sometimes makes in pop out of the gear position you've selected.
I suspect that fork issues are caused lack of fluid and bad transmission/t-case mounts. The lack of fluid thing is obvious, but the bad mount plays a role because the shifter is attached to the body, and the transfer case is attached to the frame, with a simple link between to two. If the mount goes bad and allows for excessive t-case movement, the shifter doesn't move with it, causing the fork to get loaded and unloaded with every application of the throttle or every gear change in the transmission.
The older 205's and 203's the shifter was attached to the driveline, not the body, so this issue wasn't, well, an issue
