View Full Version : a/t p light question

02-24-2009, 11:40 AM
i see people having issues with it lit up while in park, but mine is out until i put it in any gear, then the a/t p light comes on. truck drives/shifts fine. this started after i had the cluster apart to replace the park bulb. i've checked the tcase and it's definitely in gear.

all i can find about the a/t p light is that it tells you that the t case is in neutral. I did find a circuit diagram in the service manual that looks like the a/t p switch is getting power from the pnp circuit. haven't had time to check the pnp and neutral switches, but does it sound like i'm on the right track?
