A341 A340 Internals Quest

[Netg]

Is anyone familar enough with these two transmissions (a341 a340) to tell me as to whether the internals are interchangable? I need to rebuild my a341e and I will be utilizing an OEM quality rebuild kit...but if the a340's clutches/etc are the same design, I can get a transmission rebuild kit for a heavier/more powerful car to use for my transmission. I am assuming that the internals of the larger/powerful car would be sligthly stronger at least than what was put into the smaller.

I know the casings are not the same, but the a341e has (according to wiki) been used in the LS and the sequoia. The a340 has been used in some large toyota's as well like the 4x4 sequoia, the internals for the a340e and a340f (2wheel 4x4 with t-case) are the same so the casing differences don't seem to matter. Not that I need the externals, just rebuilding the insides ;)
