Tranmission temp guage

[wesmaria]

I just purchased a 2002 F350 DRW PSD with an automatic trans. About 10 seconds after I turn the key on the Trans temp guage will go to half way even if I haven't driven it for 24 hours. Is this normal? If not how can I fix it.

Thanks

could be one of at least THREE things...

bad sending unit
bad connection / pinched wire (sending unit)
bad gauge

I would say that Bush is correct with the bad connection/pinched wire diagnostic.

Thanks for the quick reply. Were is the connection to the transmission located? I saw on one post where it should be located on the drivers side but mine didn't look the same.

It is supposed to be just above the pan line on the drivers side of the transmission.

Sounds like you are talking about the factory tranny temp? If so that is buried in the tranny...

 

[DaveBen]

Where does the wire exit the transmission, CSIPD?? That is the question.

Not arguing, just looking at his sig, looks like a stock truck ... The factory sender wire is in the main loom... I dont know what color or anything. Just saying, I dont think its an aftermarket gauge . Here is a shot of the aftermarket gauge port...

Thanks, that is what I thought.

Thanks for the help. It is a stock truck. I will have to add an aftermarket temp guage.
