Hello! I have a 2000 maxima, manual transmition. In the morning when the weather is cold, i have to pump the pedal many times to be able to make it go into gears. I have had this problem for more than a year. Once the car is warm and i have pump it for a while, 3 to 5 min, the clutch us normal. I dont have any leaks, what can be the problem? any help will be appreciated. Thank you!
