Actually a great transmission. It is a bit stronger than a AX-15. It has a straight cut set of gears that give it that wine in neutral when the input shaft is spinning. Actually reminds me of the race transmissions that we use in sports cars. I really kind of like the sound.I have a 2000 XJ with the 3550, and I have an AX-15 in one of the '88 MJs. There is no comparison. First, the 3550 has a deeper first gear, so if you go off-road that helps your crawl ratio. The 3550 is MUCH smoother shifting, and it's quieter when driving. If you can get it for $500 -- go for it. Quote Posted April 27, 2015I have a 2000 XJ with the 3550, and I have an AX-15 in one of the '88 MJs. There is no comparison.
