    Hey guys. Sort of in trouble here I thought this bolt was the drain plug when I pulled it and now it won’t go back in. Anyone ever have this issue? It’s like it was threaded into something then when I removed the bolt, something inside turned and now it won’t go back in. Like the threads aren’t...

    Can't figure out this transmission issue

    I have tried finding someone who has discussed this issue in the forum before, but wasn't able to find anything. I have a 2006 LJ that will not go into gear... at all.

    NSG370 to AX15 swap

    starting this thread to document my swap instead of doing it after the fact when my memory is fuzzy. Background: my NSG370 pops out of reverse.

    Clutch Disengaged Sounds Like Marbles Rolling Around

    I have a 2001 TJ 4.0, with the clutch OUT it sounds like there's marbles rolling around or rattling, when I push clutch in it goes away. And unless I use a little more "force" than I should have to, it will grind going from 1st to 2nd. My initial thought was throw out bearing, but now I'm second...

    Transmission (auto) grinding while in gear

    2002 TJ 4.0 I first noticed it at red lights. A grinding/rattling sound coming from beneath me that disappears when I go into neutral. And it's not noticeable when I'm driving, probably drowned out. I've been leaking ATF for a while but I thought it was just a bad pan seal and now it has low...
