Transmission shuddering in your 2016 Mazda CX-5's 6-speed automatic, accompanied by P0700, indicates the transmission control module has detected issues affecting shift quality. The shudder often occurs during torque converter lockup or gear transitions.
Understanding P0700
P0700 is a generic alert indicating the transmission control module has stored specific fault codes. This requires deeper scanning to retrieve the actual codes identifying solenoid problems, clutch issues, or pressure faults.
Shudder Characteristics
Torque converter shudder typically occurs between 25-50 mph during light throttle as the converter clutch attempts lockup. The sensation feels like driving over a washboard road. Gear change shudder occurs during specific transitions.
Common Causes
Torque converter clutch material degradation is the most common shudder cause. Degraded transmission fluid loses friction modifier properties. Solenoid issues affect pressure control. The valve body can develop wear affecting hydraulic distribution.
Fluid Condition
Mazda's Skyactiv-Drive transmission is sensitive to fluid condition. Fresh fluid with proper friction modifiers often improves or resolves shudder symptoms. Regular service prevents many issues.
