P0752 Fault Code on 2008 Saturn Outlook: Shift Solenoid A Stuck On Diagnosis and Replacement Guide

Hello everyone, I hope you're all doing well. My daughter's 2008 Saturn Outlook recently triggered the P0752 diagnostic code again. This code indicates a 'Shift Solenoid A' stuck-on condition in the transmission. Previously, we had addressed a low transmission fluid level issue—her stepdad topped it off, and after adding Sea Foam transmission additive, shifting improved temporarily. However, the P075-2 code has returned despite the fluid being at proper levels and appearing in good condition. Since the code points to a stuck-on shift solenoid A, I'm now looking for reliable guidance on locating this component and where to purchase a replacement part. Unfortunately, my searches using Google (Mr. G.) have not yielded clear results about the exact location of the solenoid or where to buy it. As someone with no mechanical background, I’m hoping experienced forum members can help me understand how to identify and replace this part. Any advice on diagnosing or replacing the Shift Solenoid A in a 2008 Saturn Outlook would be greatly appreciated. Thank you all in advance for your time and expertise! — DeWyatt Smith
