Hey Eric, thanks for the videos you do, i have a longer question. I have been trying to trackdown an issue on my fathers truck. 1998 Chevy K1500(5.7 Vortec/4L60E 153000 miles). It feels like intermittent torque converter lock up in 2nd and 3rd gear. It had a P0740(Torque Converter Clutch Circuit Malfunction). We replaced the Torque Converter Clutch Solenoid, as it was bad(resistance was out of spec). After replacement, the check engine light went out, but the symptoms still exist. We also checked the resistance of the wiring harness, it was within spec and isnt shorted out and has no visible damage. Could it be the Transmission Control Module, or potentially a mechanically failing transmission.

Thanks.
