got this reply for an ex-Jeep engineer in our club:
"Up to '96, there were three different input lengths, so yes, you could run into trouble with some combinations. In '96 they standardized to the 'medium' length input, so that's what your NV241OR is...and as luck would have it that's also what the AW-4 XJ Cherokee automatic was too...so you'll be fine if you follow through on your plan."
