Yours may be a 6-speed, but I'm pretty sure that the V-6 AWD Venzas and AWD Highlanders use a different, but generally similar, transmission---I've never looked at an AWD to see how power is transmitted to the rear wheels in these vehicles. Under typical on-road use, and with the cleaning and fresh load of ATF it previously got, I wouldn't buy another flush. I prefer filter changes (Toyota's parts diagram calls the trans filter a "screen", but they're a cellulose fiber filter, not some fine wire-mesh that I'd associate with the "screen" term), and they're available from the usual suppliers on RockAuto for about half of the OEM piece. I've used ATPs previously, and have a Beck-Arnley waiting in my filter stash for the car to get to 170K miles.
Your dealer may be committed to his/her BG machine's flush program, and may not want to do a pan drop/filter change/refill. If that's the case, find a reputable transmission shop (yes, they exist), to do the work. But if you're just a dealer-only guy, their flush procedure probably won't be bad for your vehicle, given your earlier transmission maintenance. Your 75K extended warranty probably won't matter; for a normal driver, a Venza or Highlander would've made it past 75K without any transmission fluid change, which is probably what most of them get.
