It may actually be normal operation. That’s because many of today’s computer systems are designed to prevent a shift into high gear until the engine reaches normal operating temperature.
Figuring The Problem Out
Of course, if your car’s taking too long to warm up, the computer system could be locking out high gear for too long. That might be because of something as simple as a faulty or incorrect thermostat.
To see whether this condition is normal or not, take your car to your local Cottman center. Their technicians can check the computer system to see whether it’s working properly, and, if the engine isn’t warming up quickly enough, they’ll know just what to do to fix it and get your transmission operating like new.
