You can find used transmissions for $1200 to $1500 online with free shipping nationwide. Called a a local shop I use and he said $600 for an install with new filter and fluid. So running your at 5 grand with all of the major service left. That's a decent deal but after that your creeping up close to regular retail so not a bargain. Problem is they are not going for the deal. I used to buy SUV's like this easily for $2000 and under and fix them. There are just not many bargains left out there in used vehicles anymore. They have a 13 yo unit with a lunched tranny closing in on 200000 miles and won't take 3 grand....wow. I think GX 470's are no longer under the radar anymore.
