I may need to replace the transmission in my '01 4runner. I have found several used transmissions, however they all seem to only be compatible with the model years up to '99. All models '95-'03 use the A340F transmission, but all the used transmissions that I come across are listed as '95-'99. Is there something different that would make those transmissions not compatible with my '01? They are all A340F, wouldn't they be compatible?

Thanks,
Jim
