Yes, I swapped it in from a cj6 a few years ago. I pretty much never use first gear, but use second as its synchronized. Not sure if I’d bother swapping it now

David,
This helped. I don't often reference my late Service Manual, SM-1046, but bought it as it covered CJ-3B also (plus CJ-5/5A and CJ-6/6A and the DJs too). Sure enough, there was a section on the 4 speed T98. I didn't see anything in that section, J1, that mentioned lubrication. Checking the B section however, I found a note at the bottom of the page associated with the directions for lubricating the transmissions on the 4WD vehicles page.
8. Transmission:
3 Speed.....
4 Speed °..... (notice the degree symbol)
At the bottom of the page the explanation:
" ° 4-Speed transmission and transfer case require separate lubrication of each unit."
Both list GL-4 80wt. or 90wt.
Not what you wanted to read, I know. If someone else knows differently, hopefully they check in.
