FAQ

Will a 4L60E flexplate work with a 4L80E?

• No, a 4L60E flexplate is not compatible with a 4L80E transmission. The two transmissions have different torque converter bolt patterns and sizes, requiring specific flexplates for each.

How much gap between torque converter and flexplate 4L80E?

• The recommended gap between the torque converter and the flexplate for a 4L80E transmission is typically around 0.030 to 0.060 inches. This allows for proper alignment and prevents interference issues.

What is the bolt pattern on a 4L80E flexplate?

• The 4L80E flexplate has a 11 1/2 in. bolt pattern designed to match the torque converter. It is essential to use a flexplate with the correct bolt pattern for proper engagement and function.

What is the difference between a flexplate and a flywheel?

• A flexplate is used in automatic transmissions, connecting the engine's crankshaft to the torque converter. In contrast, a flywheel is used in manual transmissions, providing a mounting surface for the clutch assembly.
