OP I'd go back through the process of drain & fill. Costs you nothing but time and maybe some more fluid. Since pan was pulled off: what got disturbed while pan was off- did filter come off then maybe a solenoid wire get damaged somehow during that process? Unlikely but could have been. What fluid did you use? WS Specified compatible (Toyota WS, Aisin WS, valvoline maxlife, something else?) Fluid level: the level check procedure is a narrow heat range- 97F~115F; I'd warm up to that temp range (watch on scanguage, tech stream, or IR thermometer on pan), and then (on level ground with engine running) pull the level check plug to see if any fluid comes out.
