Hello Nick, my name is ***** ***** I am a professional here at Justanswer. Thank you for your question and I will assist you with your concern.

Are you looking for the location of the splice S107?

Customer: replied 3 months ago.
i replaced the trans. and that changed nothing the same codes are still there, i have tried testing fuses to make sure they have power to them and they do. i have tested wires that lead into the trans to make sure they have power and they do, i have read online to check splice 107 to make sure its not corrode but i have no clue where this splice is at
Expert:  Ron replied 3 months ago.

Okay, GM has the splice 107 located in the harness at The Front Left Side Of The Engine. They do not show a diagram but if you look at the harness where they say it is you should be able to find it.

Thanks, ***** ***** ever ran to this problem before?
Customer: replied 3 months ago.
what would you recommend that i do? Am i on the right path or am i way off?
Expert:  Ron replied 3 months ago.

Yes and its usually a wiring concern so your on the right path , you may also want to check your connections a Bulkhead Connector. The splice 107 is a very common cause as well. I would start first with checking it.

Customer: replied 3 months ago.
whats the bulkhead connector?
Expert:  Ron replied 3 months ago.

That the large connector that connect the main engine harness to the fire wall (bulk head) where the harness goes inside.

Customer: replied 3 months ago.
OK, I also read somewhere that there is a connector on the passenger side on the trans. that can wear down and then it will short out have you heard of that or is that for something else?
Expert:  Ron replied 3 months ago.

I have not hear of that one , and theirs nothing listed for it, from what Im seeing the S107 is the most common. Let see if we can locate it and check it first.

Customer: replied 3 months ago.
Ok, so splice 107 is the large connector that connects to the front of the trans, correct?
Expert:  Ron replied 3 months ago.

GM is showing it in the harness splice at The Front Left Side Of The Engine.

Customer: replied 3 months ago.
do you happen to have a picture of it?
Expert:  Ron replied 3 months ago.

GM dose not offer a pic, you going to need to open the harness up at the point and have a look.

Customer: replied 3 months ago.
is s107 just a wire thats in the connector? its not a real splice of two wires becoming one? or one wire wired to another?
Expert:  Ron replied 3 months ago.

Its a splice where several wire come together from a single wire.

Customer: replied 3 months ago.
does it happpen to say the color of the wires?
Expert:  Ron replied 3 months ago.

It looks like the power feed wire is going to be pink. See the wiring diagram in the link below.

Customer: replied 3 months ago.

Customer: replied 3 months ago.
