I own a 2010 Holden Cruze. I have an issue with the transmission. The gear is not shifting properly causing high rpm...

This model Holden Cruze is well known for transmission failures. Symptoms include the inability to select gears, a complete loss of drive or, as you have noticed, flaring in the gears. Unfortunately, this often mean the entire transmission is unserviceable.

Holden did extend the transmission warranty on these cars to five years or 150,000km, but even at that rate, your car would still be well and truly out of warranty. The first step, however, is to have the car scanned to see if the computer throws up any transmission-fault codes which could tell more of the story.

In some cases, these cars also experienced failed transmission coolers which allowed the transmission fluid and engine coolant to mix. If that’s the case, you might be able to get away with replacing the radiator, but historically, many of these cases also caused the transmission to fail.
