[THE NEW GUY]

I have the contrary problem: no rear transmission until I press the gas more than 1/3. And then a sudden shock. In the snow, this is critical because the front wheels are spinning, the speedometer shows up to 40kph, but the car is not moving until I press the gas a little more. the sudden shock indicates that the rear wheels are engaged and then the car moves. I changed the transmission last year and I open the tail cover (where the solenoid C is located). I used silicone to close it again (no gasked).
