WhiteComanche1989 Posted April 12, 2017 Share Posted April 12, 2017 I have a ba10/5 transmission. I'm taking it out because its sucks horribly. Anyways I am wondering what the best transmission would be. My Comanche is on 6in lift 35's and its 1ton steering with. Ford 8.8 in the rear. I just want a good reliable transmission. Please help me out here Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted April 12, 2017 Share Posted April 12, 2017 I love my 3550 , shifts great and has a slightly lower gear ratio in first. They are also plentiful in my area . Most of them will have the TJ tcase clocking unless you're lucky enough to find one from an XJ or drill the holes and clock it for the Mj .

johnj92131 Posted April 12, 2017 Share Posted April 12, 2017 When looking for an AX-5 replacement trans for my diesel swap, the knock I "heard" on the 3550 was that it could/was loud. My advice, buy whichever one you find a good deal on. Remember, the factory was happy with both. Likely also made a $$$ decision. Link to comment Share on other sites More sharing options...
schardein Posted April 14, 2017 Share Posted April 14, 2017 I have driven a few AX15s, and I have a NV3550 in my CJ7. Yes, the NV3550 does have some gear noise while just sitting with the engine running, trans in neutral, clutch released. I'm not sure it would be heard in an MJ with carpet, but I can hear it in my CJ. Both transmissions have an overdrive that offers a substantial reduction in cruising rpms, which allows you to run your axle gears a little lower if you want to and still be able to run on the highway. By contrast, the six speed NSG379 doesn't have a very steep overdrive, but makes up for it with a lower first gear. I run 35s with 4.56 . It drives great, I can take off from a dead stop with no throttle and cruise all day at 75 mph. I've driven two different NV3550s, and both of them could be a little twitchy getting into second. If you try to speed shift, it will grind sometimes. Having a split second pause while shifting 1-2 cures it, for me. As stated above, I'd take either I could find/get a good deal on.

Jtrux Posted April 14, 2017 Share Posted April 14, 2017 I prefer AX15s. They can still be bought brand new which is a big plus for me. When the 6 speed in my LJ took a dump, I swapped a brand new AX15 in it's place. Sent from my LGLS992 using Tapatalk Link to comment Share on other sites More sharing options...
