120K mile sample of factory fill Toyota ATF WS Car. I ran this much longer then I wanted to, wanted to do at 90k-100k just was being too lazy to change it earlier. Still seems like I should of changed it even before 90k with the results. Refilled with Valvoline Extended Protection ATF and will drain and fill that next one at 40k. Hopefully no major damage has been done to the transmission. I will say the car seems to be running smoother with the new Valvoline ATF in it. Only time will tell later. Hope this helps others in decisions on when the change out.
