Important Consumer Information Regarding Pontiac Transaxles
General Motors which makes Pontiac has developed and used several different trans-axles for their vehicles. The 4L60E is one of the more common GM transmissions. For accurate information about your vehicles specific transmission, please call or use our convenient online form.
4L60E Transmission
A common failure in this transmission is the sun shell. When the shell loses its splines, the transmission loses 2nd and 4th gears. All transmissions are upgraded with a hardened radiused sun shell to eliminate this weakness.
4L60E Transmissions – With these transmissions there are several points of failure. At River City Transmissions we perform all available upgrades. 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 lose 2nd, 4th and reverse gears. All Pontiac 4L60E 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 Pontiac transmission that comes through our shop.
With over 20 years experience our Master Transmission Builder has the knowledge and expertise to perform Pontiac transmission repair services to get your Pontiac 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.
