The top 5 signs your 10r80 is failing is receiving and of the following DTC trouble codes when receiving a check engine light
P0735 (Gear Ratio Error in 5th) and P2704 (Friction Element 'E' Apply Time) are common codes often indicating an issue with the 'E' clutch and a potentially faulty CDF drum or internal sleeve leakage.
P0741 (Torque Converter Clutch (TCC) Performance) or P1744 (TCC Solenoid Mechanical Stuck Off) are often associated with the "rumble strip" sensation (shudder) during light throttle cruising, pointing to torque converter problems.
P0868 (Transmission Fluid Pressure Low) is a common "main problem" code that often triggers other codes and can be a symptom of a cracked idler gear in the front pump support.
P0734 (Incorrect 4th Gear Ratio) and P07F7 (Incorrect 10th Gear Ratio) are frequently seen codes by technical services, often caused by a damaged seal ring on the No. 3 sun gear shaft.
P0756 (Shift Solenoid B Performance/Stuck Off) and P2701 (Friction Element 'C' Apply Time) are also reported by owners experiencing jerky shifts and engagement issues.
