TRANSMISSION MAKES A NOISE / SEEMS TO HOLD BACK DURING THE 1-2 SHIFT * Test drove the vehicle and felt a few harsh shifts. The transmission fluid was low but clean. The Circuits 6387 , 6388 were tested and I found 3 megaohms that would change when manipulating the harness. The ECM side terminals were clean and tight. I found transmission fluid inside the connector to the transmission fluid at xl75. It was leaking due to a bad wiring harness, as that connector is part of the entire transmission control wiring harness. 9884 labor op 8463570 labor time 1.5 + 1.0(diagnostic) + .7(OLH)removed  and replaced the wiring harness in the transmission pan belly. The SI document was flawed and the valve body needed to be removed to perform the repair so OLH was applied to remove the valve body also. Feedback was submitted on the document ID. Back to regular time, reassembled vehicle putting the transmission oil pan back together with customer pay new filters. Filled and set the transmission fluid level. Performed the adapt reset learn. Test drove the vehicle and found no further issues.
