Compatibility with a V8 is one of the strong points of the 4T80 series.

The debut in the Cadillac brand helped document the foundation of success for the 4-speed series from 1993 to 2011.

When a gearbox is rebuilt, quality can differ depending on the company doing the building. There were some OEM problems with the 4-speed automatics built by GM during the regular production years. A builder who understands what to look for can make sure that a buyer is not plagued with common failures.

Tested 4L80E Automatic Transmission

While a warranty helps, it is mechanical and digital testing that make a huge difference. Since leaks are one problem, a series of compression tests can be applied to any GM gearbox. This ensures that a good seal is present and no fluid will be drained prematurely. A General Motors vehicle that has been sitting for along period of time can be prone to leaks.

Inside every 4L80E gearbox, a series of shift solenoids are present. These can fail causing lockup or stalling during shifting. The rebuilt PowertrainPros.com inventory on this page has been tested for these issues. An expert handles each building task and compares functionality to a new assembly. Only the best units are then offered for public sale.
