Hi and thanks for contacting YourMechanic. It won’t matter what type of oil was put in the gear box as long as the viscosity was the same. You can try replacing the oil and see if it makes any difference, but most likely not. There are two sensors on the transmission, the output shaft sensor VSS (vehicle speed sensor) and the input shaft speed sensor. The input shaft speed sensor tells the computer how fast the transmission is input speed is compared to the output speed. I recommend replacing the input shaft speed sensor. If you need further assistance diagnosing your vehicle, then seek out a professional, such as one from YourMechanic, to help you with your sensor.
