Important Consumer Information Regarding Chevrolet Transmission Repair:

General Motors has developed a wide variety of transmissions and transaxles for their vehicles. For accurate phone support, it is necessary to have the year, make, model and engine size of the vehicle to correctly identify your transmission. Thank you for choosing River City Transmissions.

4L60E Transmission:

4L60E Transmissions – With these transmissions there are several points of failure. At River City Transmissions we do all the upgrades available. Some of these upgrades are the sun shell splines, as these can strip off, or the hub containing the splines break off causing you to loose 2nd, 4th and reverse gears. All Chevrolet 4L60E Transmissions at River City Transmissions get a new hardened sun shell with every rebuild.

Another common problem is the 3/4 clutches and 2/4 bands get burned up. At River City Transmissions we use high energy lined clutches and bands to ensure a long life from these components. These are just a few of the many upgrades we do on every Chevrolet transmission that comes through our shop. At River City Transmissions we want to make sure that our customers are able to enjoy their vehicles for many more miles to come.chevrolet chevy auto repair, transmission and clutch replacement in SE Portland by River City Transmission
