2004 Toyota Truck Sienna AWD 3.3L MFI DOHC 6cyl

I am looking for an automatic transmission for my 2004 minivan. These are the details:

Application: Transmission model U151F

I've looked in Ebay and in craigslist and found it for about $1200-1500

A while ago I saw in Craiglist for $500 bucks, I should have buy it, but now its hard to find a AWD transmission. My car is sitting in the driveway and I hate to see it there because the poort car doesn't run anymore.

How much will it cost to fid it?\

One place I found it also brand new or rebuilt is at autozone: https://www.autozone.com/drivetrain/automatic-transmission/toyota/sienna
