Did you prime the new pump with some engine oil? Another trick is to use some light grease to coat the pump gears so they will seal against themselves. If you primed the pump and are sure the pump is working, you may have worn out engine bearings or some internal oil leak that is keeping the oil from getting pressure.
try to change the trans oil and filter possibly need to change, looks like a transmission shift solenoid is the problem or trans computer the oil and temperature will get it last longer also but would likely recommend to have it diagnose by a transmission specialist to fine what causing it
have the oil pressure checked ... if you are not using too low a viscositity of oil (the weight) you might be able to use a thicker weight oil to raise the pressure.
the oil should be black,brown or gold(new) with no other colors in it. shouldnt be milky or streaky. the trans fluid should be light red or semi light red.as for the engine being oily its hard to discern unless you rinse it off to metal and drive it. if you mean the oil pan has black oil on it then it may be ok.
remove the the diff unit and refit into your casing ,,,easy job,Preload on pinion bearings and set crownwheel backlash to a very small wiggle woggle.handful of LM grease in unit before you refit cover then use ep90 gear oil .job done shouldnt take more than a morning to do.
When you say "warning light is on", I assume you are not talking about the oil pressure gauge...
If not, here is your solution:
What you have is a very common problem: The oil LEVEL sensor has failed. Previas have 2 sensors; pressure & level of the oil in the pan...What you need to do is replace it, Toyota part number : 89491-28030.
BUT...This part is $380.45. Not cheap; Sorry but true.
