Think I blew front pump in 700R4

I was in light traffic at a light, light turned green, I accelerated lightly, car began to move, then almost with no sound- nothing. no gears at all. Engine doesn't change rpm when I put into gear. Put car up on jack stands and took off flexplate cover, no visual issues, inspected linkage, cables, everything- no issues. Check fluid, color is normal and does not smell burnt. Fluid level appears very high, was not overfilled before. when turn car on fluid level does not appear to change much, if at all. My question is, why did the fluid level suddenly get so high? Is this an indication of torque converter failure or front pump?
Second question- is this something I can fix? I just don't have the 1500+ the shops are asking.
