My transmission just out of the blue stopped working. My son was driving when the car would not go into any gears. Yes, the car has 103,000 miles on it, but I had no type of warning at all. The shop that had my car states, " when it's cooled down, the car drives regularly but when the transmission fluid warms up, the pressure in transmission drops and will not allow vehicle to shift into gear." Apparently I have to get the whole transmission replace which is going to run me anywhere from $3,000 - $5,200. Who has that kind of money to spend! I need some suggestions please.
