Need help on tranny.
 

Ok so here's the situation. My dad has a 96 Dodge Ram 1500 with a 318(5.2L I think). Well all of the sudden it decided it wasn't going to shift out of first even in like drive or 2nd. It's a A3 with the push putten O/D. I talked to a service station today because I know them pretty well and we found out it's not sucking any oil down in neutra. Tranny oil's good also. Well he then told me to call a transmission shop, so I did and told him the story and he told me to check the wiring, so i did and nothing doing. So if anyone has any experience or has ANY knowledge on this subject please help. Thanks...
