    I am new to this forum so I am not sure I am posting in the correct place. Please let me know if I am not.

    I am trying to replace the transmission for my 1987 YJ. I'm not a mechanic, but my understanding is that it's a 4L, 6 Cylinder. I've tried a few difference transmission shops locally and haven't had any luck finding parts or a replacement. Any guidance would be very much appreciated.

    Thank you in advance for your time!
    Jeremy

    87 Wrangler, kind of...
    5.7 V8 with Whipple Supercharger, TH350 w/B&M Shifter, NP205 TC, Dana 60 front 4.56, GM 14 bolt 10.5 rear 4.56, 4 wheel discs, Bilstein shocks, 6" lift on 37's, Autometer gauges, all led lighting and a few other things.
    1987 stock inline 6 is an AMC 4.2 liter (258 cid). 4.0 FI wasn't available in Wrangler until '91.
    Peugeot BA-10 was the five-speed manual transmission. NP207 transfer case.
    Parts and rebuild kits for BA-10 are available at https://www.quadratec.com/jeep-replacement-parts/jeep-transmissions/ba105.php
    No shops I've heard about selling rebuilt BA-10's. Verify your engine and transmission combo and find a good tranny shop to rebuild the one you've got.
    Let the forum know what you figure out.
