    Hello,


    Will a 1988 Mondial 8 transmission directly interchange with a 1982? Have a trashed transmission and am looking to change them out if there is no compatibility issues. Thanks guys.

    As suggested the first time you asked the question try the Mondial section

    However it may not be that easy since

    a - there was no Mondial 8 in 1988

    b - many variations in similar transmissions http://www.clubscuderia.co.uk/forum/index.php

    I believe the short answer is "no" (within the limit of "directly"). On the 3.2, they added another bearing to support the outer end of the gearbox input shaft -- so the transfer gear housing and the gearbox input shaft are different. Whether or not you could put an '82 gearbox input shaft into an '88 gearbox and have it all work in an '82 -- I have no idea ;).

    You should have a look at the SPC illustrations available at the F parts suppliers (like at www.ricambiamerica.com) -- the page labeled "GEARBOX TRANSMISSION" for each will show the difference mentioned above (i.e., the Mondial 3.2 has bearing item 10, the Mondial 8 does not).

    I'm not clear from what you've stated above, as a "1988 Mondial 8". Because in 1988 the Mondial version was the "3.2 Mondial" --- with a 3.2L engine. In 1982, the version was still the "Mondial 8" with a 3.0L engine.

    The transaxles from an "8" and a "3.2" are not interchangeable. In addition to different internals, the bell housing / transfer case housing have slightly different geometry, and the clutch mechanisms are quite different. This is certainly a fact with the 308/328 cars, and I'm quite certain it is the case with the Mondials as well, since both models shared the same power plants (other than gear ratio variations).

    If you need more details, you may wish to post this in the Mondial section of the forum ---- there are several folks there who are intimately familiar those cars.

    I'll bet if you had enough of the parts from both cars you might be able to make it work.

    Not sure why you'd want to though.

    Probably true, but it could be a helluva "little project" even for a pro. Coincidentally, I just went through this trade about a year ago with my 308-2V-i, and I quickly decided it was far easier, and very little extra $$$, just to drop in a complete, used 328 engine / trans / gearbox --- rather than trying to mate the existing 3.0L engine to the 328 trans / gearbox.

    Of course, the 328 engine is going out West to be "bumped" up to a larger displacement conversion first ---- I wanted the combination of the improved 328 mechanical package (over the 308 unit) plus extra power. :) Dropping the 328 unit into a 308 chassis is essentially plug-and-play, but I believe doing so on a Mondial ("3.2" unit into an "8" chassis) is more complicated and may well require some minor, structural modifications and repositioning / alteration of some ancillary components.
