i cannot seem to get my truck out of park sometimes, if i play with it sooner or later it will come out. I have tried switching the pedel position switch and nothing. any ideas?

Matt

 

Did you ever do anything to the shifter or the tranny? Anything major that might have knocked it out of alignment or whatever?
Floor or column shift?

 

colum shift, and no... nothing has been changed

Matt

 

Hmm...might post this in the tranny section, they are more knowledgeble than I am about it. I don't get the whole automatic tranny thing, I believe there is a cable that runs from the shifter to the transmission, I would assume that would have something to do with the problem. Sorry I can't be of more help.

Yes
REPLACE the shift lock actuator. TEST the system for normal operation.

No
REPAIR Circuit 57 (BK) for an open. TEST the system for normal operation.

 

wow, i had trouble reading this. yes it is the stering wheel lock thing that wont let it out of park...

Matt

 

Sorry but I can never get it to paste much better, each test starts with A1, A2, etc.

 

wow, this is going to get complicated real fast... i may have someone print me a service off all data
