T-999 Transmissions on 80-86 CJ7's

Were the T-999 tranny's made different in the later models. I am currently doing a swap from an 82' to and 86' T-999. we noticed that there is a difference in the input shaft between the two of them, which would not allow the torque converter to fit on the newer model tranny. Does anyone have any ideas to why this is so or should the torque converter fit on both trannys?

The difference on the shafts is very small. the input shaft tip on the 82' tranny is smooth (meaning the splines do not go all the way to the end) and there are 27 splines on the rest of the shaft. ON the 86' tranny input shaft there are 26 splines and they go all the way to the end of the shaft.....if that makes sense.

Yep it makes perfect sense, one uses a lock up converter, the other a non lock up. On a tranny that uses a lock up converter the splines stop short, while a non lock up go all the way to the end

OK thanks thats what I was thinking but I was not sure what consituted a lock up converter or not. Will it make a difference whether or not I put a non lock converter in my cj that originally had a lock up converter? If so, what will be the difference? Will it work?

Maybe ask if it is possible to swap shafts?
