High mileage issues, anything common?

I haven't heard anything bad on the transmissions. I know after 2003 they are a sealed unit and supposedly don't need servicing.

I have heard that also...I'm always leary when I hear "sealed" or "lifetime". The transmission on my wife's IS350 is also sealed, initially I thought I could at least tap into the transmission fluid as it is pumped to some cooler somewhere..nope, it's not pumped to a cooler, on that car the coolant is pumped back to the transmission and to a heat exchanger right on the side of the transmission, so it really is rather sealed.

No locker. Not needed unless you plan on taking it where you shouldn't be.

GX470 uses the same 5 speed auto tranny (A750F) as the 03-07 100 series Land Cruiser so I'm confident it's as, if not more, reliable as anything else out there.
