OBD2 Code P0736 on 2003 Dodge Grand Caravan: Transmission Downshifting and Speedometer Jump Issue

Model: 2003 Dodge Grand Caravan Fault Code: P0736 Posted: 2019-02-12 16:08

I recently received a diagnostic code P0736 on my 2003 Dodge Grand Caravan. The issue occurs when I'm driving and begin to slow down or come to a stop—during this moment, the transmission suddenly downshifts aggressively. This causes the speedometer to jump sharply to 20 mph even though the vehicle is stationary with the foot brake fully applied. There are no noticeable drivability problems in reverse, but the behavior in drive while decelerating is concerning and affects driving confidence. I'm seeking advice on whether this is a transmission issue or a sensor-related problem, especially given that P0736 relates to transmission gear position mismatch.
