I have a 2003 s-10 truck, and I have been having many problems with this truck. Right now i get SERVICE CODES P0758, P0740, P0753, P0785, and i have replaced the TCC solenoid and the wiring harness, i have also replaced both a and b solenoids. and still had the codes showing. I was told to try the ignition switch harnes, and that also did not fix my problems. I have no gauges,(only alt, and oil pressure), and it feels like i am stuck in 2nd gear, and there seems to be no power to go at all. Could it be my computer needs to be flashed or maybe a relay i don't know about? Please Help. Thanx

I'm having a problem with my Yukon right now and have to switch out the solenoid. tell me how hard is it to switch out the solenoid and is it internal?

Best to start your own New thread and give us all info and codes before throwing parts at it.

Clear codes and see which one comes back first.

Your codes you have now are 4 different solenoids or solenoids circuit problems.
4 codes together is more wiring/power/ground problems.
If all 4 codes come back check transmission valve body solenoids wiring and power and grounds.
Also check fuse and fuse box power feed.
And check transmission range switch wiring and plug in and power feed.

Hi
I just had the same problem on my 97 balzer and you will not belive the fix but think about it. You have multiple selinoids giving you problems. So it's a problem common to all and it's too many to die at one time. Replace the ignition switch and it will fix the problem. It did mine $95. check out this site where I got the answer

That's not a website, that's a link to something on your own computer.
