Although many people said that General Motors was trying to copy the Chrysler PT cruiser, the Chevrolet HHR turned out to be quite a successful little car in its own right. It was just the right size. It looked great, and had just enough power to make it interesting. Unfortunately though, Chevy HHR transmission problems can happen as they get older. So let’s figure out what you can do about them.

Chevy HHR Transmission Recalls
2009 Chevrolet HHR Recall 09V073000 / 09041
Summary – On some 2009 Chevy HHR’s, the transmission shift cable adjustment clip may come loose, causing the gear indicator to display the wrong gear.
Consequence – If this problem occurs, the driver could remove the ignition key and exit the vehicle thinking the transmission is in Park, even though it isn’t. This can lead to a rollaway, which can cause injury and/or property damage. A lesser consequence would be the inability to start the vehicle because the transmission is not in Park.
Remedy – This recall began on March 24, 2009, and Chevrolet dealers were instructed to inspect and replace any affected transmission shift cable adjustment clips, free of charge. Owners can contact Chevrolet at 1-800-630-2438, referring to recall # 09041. Or they can call the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236

Can I drive with a transmission problem?
Obviously if your transmission is just slipping, hanging in a gear, or making a funny noise, you could probably still drive your car. However, Chevrolet HHR transmission problems can go from simple to expensive very quickly. So do yourself and your budget a favor, and have your car checked out by a mechanic sooner rather than later.
How often does a Chevy HHR transmission need to be replaced?
If you have your transmission serviced regularly and you don’t drive like a hooligan, then your Chevy HHR 4T45E could last anywhere from 120,000-180,000 miles. But OE design flaws can also shorten the service life, and most used and rebuilt transmissions will suffer from these same issues. A remanufactured Chevy HHR transmission on the other hand, could last a lot longer if the proper modifications have been made to address the known design issues.
How are Chevy HHR transmission issues diagnosed?
Thanks to the magic of computers, most of your vehicle’s systems are closely monitored by the on-board diagnostic system (OBDII). This allows a mechanic to connect an OBDII code scanner to the vehicle, then download the diagnostic trouble codes (DTCs). These codes can often reveal the source of your Chevy HHR transmission problems. But a visual inspection is often necessary to verify that the code is correct.
How is a Chevy HHR transmission replaced?
Replacing a Chevrolet HHR 4T45E means that the old one will have to come out. To do this, it will have to be disconnected from the engine and driveshafts, and that usually means pulling the motor partially or completely out of the vehicle. For an experienced mechanic with the right tools, this isn’t as difficult a job as it might sound. But it does require some skill and patience.

How to Solve Chevy HHR Transmission Problems
Solution A: Buy a Used Chevy HHR Transmission
While transmission problems are one of the most expensive aspects of owning a car, you should think long and hard before you buy a used 4T45E transmission. You have no way of knowing the true condition of the internal components. So it’s possible that you could have the same problems, or worse. Plus, that junkyard warranty will only get you a replacement transmission if something goes wrong. And, you will probably have to pay the labor charges to install it.
Solution B: Buy a Rebuilt Chevy HHR Transmission
Another option would be to get a rebuilt 4T45 transmission from a local transmission repair center or mechanic. They will usually replace all of the common wear parts using an OE master rebuild kit, then give you a warranty that may only be good at the shop that built it. And don’t forget, if they take it back to the factory specifications, then all of the common problems are likely to return.
Solution C: Buy a Remanufactured Chevy HHR Transmission
To get the most reliability for your repair dollars, you may want to consider a remanufactured 4T45 transmission. These are slightly more expensive than a rebuilt transmission, but they are typically built in a factory and of a much higher quality. Many of the top transmission remanufacturing companies modify their Chevy HHR 4T45E transmissions to compensate for the factory design flaws. And you may even be able to get a nationwide warranty.
