2007 Chevy Uplander P0961 Code: Frequent Hard Shifting in 2nd Gear After Transmission Rebuild

Model: 2007 Chevy Uplander Fault Code: P0961 Posted: 2020-10-06 05:16

Hi, I own a 2007 Chevrolet Uplander and recently encountered Diagnostic Trouble Code (DTC) P0961. The vehicle experiences hard shifting issues, typically occurring once or twice per month during second gear operation. Notably, the P0961 code appears intermittently—disappearing and reappearing over time. My transmission was professionally rebuilt approximately one year ago. I'm seeking advice on whether this issue is related to the rebuild or if it points to a deeper transmission or sensor problem. Any insights into potential causes or solutions for P0961 in a 2007 Uplander would be greatly appreciated.
