Truck will not shift from Park (electrical)

[Jake]

Coming home today I stopped to get the mail. Put in park, now it won't come out of park, no brake lights, no "P" lit up. You can shut it off and get it shifted to neutral, start up and it's just fine with the exception of no brake lights. Brake lights do work with 4 way flashers on.

Fuse 18 good
Fuse 21 I dropped into the abyss
31 good
35 good

Any ideas?

Well fuse 21 was blown, replaced and it's working now.

Does anybody have the wiring diagrams for this circuit?

When I shifted to park the P flickered then stayed solid. Well into the hunt to find this.

First guess would be the brake switch on the brake pedal

Brake switch is good, looks like it's the switch that senses if it's in park. The truck keeps saying shift to park as it doesn't think it's in park.

You may wanna block the wheels crawl under and see where cable hooks on lever of trans its adjustable it may not be pushing the lever back enough, i have replace a few of these cables and ran into this issue

It's the shift cable. How do you adjust it? Im going to let it cool down some and bring it in to the shop. Looks like there is a adjustment right above the linkage connector.

Update....

It was the transmission range sensor inside the transmission.

Went to unplug it, and it pulled the sensor out of the switch body.

New switch in it's all happy now.
