Evo X SST Transmission Failure

Neighbors what’s good! So I’ve been hearing a weird sound when i start the car after it’s been sitting and I found out that the Evo needs a transaxle! I went to place an order but no one in my area has one and the only transmission in my area is 12,358.32.! The car needs a Trans Axle but i'm going to upgrade the trans at the same time.
