    Hi!

    Long time reader, first time poster.

    I'm about to start a new build and have a question about the compatibility of H151f gearboxes from 80 and 100 series Landcruisers. Are there any variations between the input shafts and transmission case-to-bellhousing bolt patterns from different model years that would prevent interchanging 80 and 100 series gearboxes? Are they all the same 14-spline, 32mm input shaft?

    I've searched the forums and can't seem to find this specific info.

    Thanks!

    well we don't see any 100 series with manual .. but in Australia they came behind 2UZ and came match with H151 tranny .. as well as 1FZ-FE .

    so to my knowledge all H151 came with 14 coarse splines input and uses 300mm clutch setup .. and yes all the same tranny ..

    Note there is an H150 came behind 1HZ it's the same tranny in the exterior but with 21 splines input ( fine spline ) and lower gear ratios .. ( 1st and second gear )

    Thanks for the reply. The 2uz is what I'm going to mate the H151 up to. I was just trying to confirm that a box out of an 80 series would mate up to the UZJ100 bellhousing. Sounds like it will. Guess I'll know for sure when the Toyota parts get here from Australia. Thanks!

    Trevor,

    Excuse my dumb question, but are you planning on putting a manual tranny into your 100 series? I'd love to see a thread on this process as you're doing it.....

    I don't see any reason why it wouldn't. An A343F transmission will swap between the 80 and 100 series

    Sorry for the late reply...

    No, I am planning on stuffing a 2UZ/H151 combo into my '71 40 series. I've got most of the parts together. Still waiting on the tranny from Oz. Any day now!
