The gearing may be bad, the tranny may be slipping, or the fluid and filter may simply need to be replaced. A bad filter and low or bad fluid can cause slipping or lack of shifting.
Most common were 4l60 & 4l80
Most common were 4l60 & 4l80
The 4L60 model was the most common. There were the heavier 4L80 and the old 400thm available.

Yes, a 4L80 transmission can work with a 1993 454 carbureted engine, but some modifications may be necessary. The 4L80 is an electronically controlled transmission, so you'll need to integrate a compatible transmission controller or modify the engine's wiring to accommodate it. Additionally, ensure that the transmission's input and output shaft lengths match your application, as well as the necessary mounts and driveshaft compatibility.
Most of these had the 4L60 (700R4 updated) Some had the 4L80 (overdrive lock up variant of the old 400) if the diesel, Big block or towing or off road option packages were included
No, a 4L80-E transmission will not directly bolt to a Duramax motor. The Duramax engines typically use the Allison transmission or the 6L80/6L90 series for their applications. If you want to use a 4L80-E with a Duramax, you would need an adapter plate and possibly other modifications to ensure proper fit and function.
The governor on a 4L80-E transmission is located in the tail housing of the transmission. It is responsible for regulating line pressure and shifting based on vehicle speed, using a gear-driven mechanism that responds to the transmission's input speed. This component plays a crucial role in ensuring smooth shifting and appropriate transmission operation.
