Hi, I got the pleasure of working on my step fathers car and I pulled up dtc p1780 with my scanner so assumed it was the park /neutral sw. so 229 dollars later I have the same problem. Heres where it gets interesting Everything works correctly according to my scanner until I push down on the brake and the scanners is saying reverse is engaged.The light on the dash comes on saying its in reverse. I'm Leaning towards the ecu now????? dont want to spend alot of money on another part and not fix it. any help would be great. thanks,Jim V
