Transmission code nt710?

Okay, I had to change my transmission and everything went smoothly but now for some reason my transmission won't shift and I connected my scanner which is a Foxwell nt710 and it tells me that the vlp has high Pressure.
For a long time. My scanner won't let me clear the vlp and so I need to find a way to clear it without taking it to a shop and without a scanner, please. Any help would be helpful. Thank you
