RE: 01' supercrew, V8, 4.6

Pulled up to a gas`station to empty some old oil (didn't even turn off ignition), got back in and reverse was gone! Drive too but that eventually came back.
A friend hooked up a diag to the puter & said its the shift sensor, I think its called the "neutral saftey switch"?

Sound familiar?

Anyway, I can't find it anywhere & will probably have to go to FORD and be raped for it?!?!

Any help, experiences, advice will be appreciated guys -
