All 1999 4x4 systems the same?

[Qyota]

I have a '99 limited with the multi-mode AWD/4WD system (A340F trans). I'm looking for a donor transmission, and I want to be sure another A340F is going to fit. Did the 99 SR5 4x4 have the same trans? Is all of the multi-mode gadgetry (sorry) in the ECM and transfer case, and any A340F will do?

Thanks!

I don't know about compatibility but I can tell you that not all 99's have the same 4x4 system. Mine is an SR5 and has the conventional (i.e. no center diff) 4wd system.
