The focus of the ABS and the transmission was looked

Good morning
I have a Ford F-150 mod. 1997 Automatic, and yesterday it refers abruptly and after that the focus of the ABS was caught on the board I put it in parking and then I did not let me make the changes they were locked, after many attempts I turn off the motorcycles of the truck I opened my switch and so I let the changes put it in neutral and the prenndi and I could already start it.
But the truck feels fancy ... And the focus of the ABS is still on

if I turn it on and I want to make the changes I do not leave me I have to turn off the swich and put it in neutral to turn it on and then put it in the (d) to advance.

What should I do ..? WILL YOU WILL BE FARED ..? And the machine is protected because it has the ABS code on that is why it does not let me make the changes ... or will it be the transmission ..?

Thanks for your help

Look at the truth, I don't have a lot of the subject, I do not handle automatic boxes, but I think that when the marches are stopped, I do not enter safety, I am not sure but at some point I fuck the automatic boxes and the ABS brakes anyway and the ABS brakes are complicated to fix them oneself, take it to a workshop and tell them the brake, do not mention the box only the brake so they will not charge you.
