    I've got a 1985 CJ7 with the T5 transmission. Seems that I need new synchros as 4th isn't smooth shifting into and reverse is popping out.

    Seems difficult to find anyone that works on manual transmissions these days though I know I can go that route, but I'm considering my options.

    I'm trying to decide whether to put new synchros/rebuild the T5, or while I'm at it do an automatic transmission swap.

    I'm looking for advice from those who have done either as well as a ballpark on what I can expect to pay for the automatic swap.

    The transmission is behind a SBC 350. Axles are dana 30 front and AMC 20 rear which I also intend to either regear or swap out at some point. The stamp indicates 3.31 gearing and it definitely needs to be changed. I have the ability to pick up a Dana 44 front and Dana 60 rear with ARB lockers geared 4.56, but I'm not sure if that would be overkill.

    Thoughts and advice appreciated!
