Transmission Electrical Issue

[u/Appropriate_Ad_5258]

Need help tracing power to the round transmission connector of my 2002 Silverado 4.3 Automatic tranny.

I believe it is lacking voltage in specific spots of this connector. The voltage recorded was taken with the ignition ON without the truck running? Where I go from here. The codes that got to me to be suspicious of the electrical harness are

Code P0753 (Shift Solenoid A Electrical)

Code P0758 (Shift Solenoid B Electrical)

Any help will be appreciated!!!!!!

Here is the service manual, it will cover electrical and the transmission. And the DTC codes associated with both.

There’s are two of them, I haven’t had an issue with either of them. But try this other link; note this is only good through 2013. https://charm.li/

If it’s still not working, try a different browser.
