4T80E [93-UP] Automatic Transmission Friction Clutch Pack Clutch Module

When the clutch pack module in a 4T80E unit is worn or damaged, shift feel deteriorates and internal pressure balance is affected, making a correct replacement the starting point of any reliable repair. This listing covers a single standard-specification clutch pack module built for the 4T80E automatic transmission, applicable to units from 1993 onward.

Unlike kits assembled from multiple components, this is one precisely defined module. That distinction matters on the workbench: you are ordering one part with a known specification, not sorting through a mixed assortment. The 4T80E is a demanding unit with tight tolerances in its clutch circuit, and a module that does not meet standard dimensions will affect how the pack seats and how pressure is distributed through the apply circuit.

The part ships at 5 lb. There are no additional components packed inside the box alongside the module, so your order confirmation is straightforward: one module, standard spec, for the 4T80E.

Before placing the order, pull the transmission code directly from the unit and confirm it reads 4T80E. Also verify that the production year of the transmission falls within the 1993-and-up application range. Vehicle make and model alone are not a reliable way to confirm which transmission is installed, since the same vehicle line sometimes used more than one unit across model years. Matching the transmission code is the only step that removes uncertainty.

• Designed for the 4T80E automatic transmission, this clutch pack module addresses worn or slipping clutch engagement and helps restore proper shift behavior in the affected unit.
• This listing is for a single clutch pack module only. It does not include friction discs as a separate set, steel plates, seals, Automatic Transmission Filter, or any additional components. Confirm what your repair requires before ordering.
• The 4T80E platform demands precise clutch pack fitment to maintain line pressure response. This module is built to standard specification for that unit, not adapted from a generic part.
• Content: one clutch pack module, standard specification. Shipping weight is 5 lb. No sub-components are packed separately inside the box.
• Before ordering, verify the transmission code on your unit matches 4T80E and that your application falls within the 1993-and-up range. Do not rely on vehicle make or model alone to confirm fitment.
