I specifically asked for a transmission service based on the 60,000 mile recommendation in the maintenance schedule. The dealer said they do a flush and I asked specifically for OEM WS Toyota fluid. They confirmed that is what they use. When I got my receipt I asked the parts guy what the codes were, he said aftermarket? He knows me and he knows I always buy Toyota oil and parts. I told him I did ask for WS and asked for the manager. Now the manager comes clean and says they use a system by BG to flush the transmission completely. He shows me a flyer, now after the fact that it's been done, but didn't show it to me before. It states it needs to be done every 30,000 mi now but he insists it's better than OEM. I am not happy I want OEM fluid and I told him that. He doesn't know how it can be done. Does anyone know if they can just do another transfer through the machine using WS? I'll never go back there again what a mistake..
