If your Explorer’s automatic transmission is slipping, hesitating, or jerking between gears, it’s likely due to low fluid, a failing solenoid, or a worn valve body. Here are the top culprits and whether you should keep driving.
Common Causes of Delayed, Jerky Shifts
When your Ford Explorer VI’s transmission starts slipping—especially with a noticeable delay and a harsh, jerky engagement—the root cause is often something you can diagnose before committing to a rebuild. The most frequent issues include low or contaminated transmission fluid, a failing torque converter clutch solenoid, or a worn valve body bore. Start by checking the fluid level and condition (dark or burnt smell is a red flag). If the fluid is full and clean, the next suspects are the TSS (Turbine Speed Sensor) and the OSS (Output Speed Sensor)—both can confuse the TCM and cause hesitant shifts.
