Can someone please help me out and tell me what the differences (if any) there is in these gearboxes, they are both 5 speed manuals out of a Subaru Liberty wagon 1999 model GEN3 with selective AWD, 5speed manual EJ20. Here are the ID numbers on both boxes TY754XRAAA and TY754XKAAA. As you will notice there is only 1 difference and that is at the 7th letter. I need to know if the TY754XKAAA will replace the TY754XRAAA without any modifications being needed? If there are any modifications needed for this swap can you please list them for me as well. Thankyou kindly for your help

We have no listing of a 2.5L liberty. If this is a diesel that is why in US we don'thave that model. However the k indicates a FWD trans. But the difference may be because the 2.5L is for diesel models which the K would probably have electronics that operate different than for the diesel.

From what I can tell the impresa here in US has the 2.5L and all are the same it looks like. A lot of those numbers are used for id when in production if the other trans doesn't have the 2gearstick then you can't use it.
