If you know anybody with a GM tech2 that aint a bad thing either but even the issues with the Snap On were related to timing not tranny codes.

 

i need a good day to go through everything now

 

ok now i will have to find some sort of wire diagram for the computer and it hooks up to the scanner. any ideas where i can find one?

I went to a tranny shop here in town and asked for some help. i got "if i get out free information i cant make a living". so i wen to the gm dealer ask for a wire diagram. "nope sorry" wow. but life goes on i'll figure it out.

went to the library today and found out that i can look at manuals on-line, didnt not know that

 

still no codes.. i went through most of the grounds under the hood. going to change the fluild in the tranny, and well im there i'll check the wires and connectors.
can anyone tell me how to check the solenoides well im there?

 

update

ok guys got it fixed i think the grounds were apart of the problem. I got a code P0118 and i ended up changing out the coolant tempature sensor.
truck runs geat.

 

grounds are always the first thing to check on these trucks,especially the 3 at the rear of the passenger side intake.

 

those tree where really bad.
