Well I recently, about a month ago, did the STi trans swap on my WRX. I went ahead and got a JDM v7 trans after my 5 speed went, my guess, the sti engine swap I did earlier wore down my glass 5MT trans. My issue is now with the STi trans, I don't know if this is common but for some reason at normal rmps (2.5k -3k) when going to 5th gear, the gear tends to pop out into neutral. I've have not heard any gears grinding, it simply pops out and its getting annoying. Any ideas????
