just pulled the motor on my new to me 04 wrx to do various maintenance to the engine and seals replacement, rear main, oil pan., i even ordered a new exedy clutch kit from Rockauto for this year....anyways i discovered that this transmission is not the original. when i removed the starter to get the the large plug on the side of the transmission to remove the pin that holds the clutch fork it was not there...then i realized this transmission looks identical to the one that was in my old 02' impreza 2.5rs and 05' 2.5 NA legacy.. it has female axles with the transmission having a male stub sticking out where the axles attach.

unfortunately the tranny has NO sticker or other identification labels ANYWHERE. i looked all over the only sticker was on top of the bell housing with numbers that mean nothing?

looking at the vin badge under the hood it shows this as the transmission type: TY754VV4AA ..doing a quick google search shows this is physically NOT the transmission thats currently in my wrx

attached are photos of the the throw out bearing and misc areas to help possibly identify it?? id really like to install a new clutch kit while i have the motor out so i really need help to figure this out

thanks all!!!
