Important Consumer Information Regarding Cadillac Transaxles:
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:

There are several points of failure in the 4L60E transmissions. At River City Transmissions, we do all the available upgrades, including the sun shell spline upgrade. Sun shell spines can strip off, or the hub containing the splines can break, causing you to lose 2nd, 4th and reverse gears. All Cadillac 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 Cadillac 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.

With over 20 years of experience providing Cadillac transmission repair services, our Master Transmission Builder has the knowledge and expertise to get your Cadillac vehicle back on the road. We are so confident in our transmission rebuilding that we give every transmission that comes through our shop a 12 month, 12,000 mile warranty FREE.
