Specs on mystery Legacy auto trans

[ShaneHobson]

I have a Subaru SVX which shudders at low speed. We have discovered that the replacement automatic transmission fitted to it (sourced from my parts SVX) was originally fitted into a 1994-96 non-turbo Legacy.

Transmission type = TZ102YBABA-CF

We suspect the problem is the centre diff is under stress because the rear diff ratio in an SVX is 3.9:1, but the trans (ex. Legacy) is expecting 4.1 or 4.44.

Can someone here from the Legacy community confirm for me the final drive ratio on this transmission ?

We think the solution is to simply swap the diff from the parts car across to the good car, so that the trans is mated up to it\'s original diff again (assuming the diff was replaced when the trans was replaced).

But we want to try to test this theory before spending a lot of time swapping parts over.

Secondly, if there is anyone here who wants to earn some cash over the holiday season and would like to swap over the diffs at my place (near Hamilton). I\'ll be happy to pay cash and feed you well. I can provide a concrete floored, covered workshop to work in but you\'ll need to supply your own tools.

cheers, Shane

I would say swap the diff from the parts car over dude.....

yup same here That will be the issue as the diff ratios are certianly different

but the rear diff in the svx is slight different to the legacy in terms of how it mounts? i remember this for some reason that with people doing a manual conversion that they had to sway the internals of the diff to make it work rather can just swapping it over. Could be wrong tho and if thats the case do you want to sell you svx?

[ShaneHobson]

Because the trans (and therefore the rear diff) came from an SVX then if the guts do have to be swapped over, then I expect that was done by the previous owner when they fitted the Legacy trans into the SVX.

I do have a spare SVX here (not the parts car), reg : YZ4677 that I\'d be interested in selling. I suspect though that the market price these days is much less than I\'d want for it.
