Are USDM gsr trannys interchangeable with JDM ITR trannys? I hit a pot hole the other night and it cracked my tranny. I have a spare GSR tranny that I'm going to swap in. I want to make sure that it's interchangeable. Will i lose the LSD if i am just swapping the case.

 

yes you can use the gsr tranny and if youre just swapping cases than im pretty sure you could still use everything else
