When rebuilding a 10L80 or 10L90 automatic transmission and the clutch pack friction is the specific part you need, this GPZ unit covers applications from 2017 forward. What separates this friction from a standard paper clutch is the GPZ material itself: it is formulated to absorb and dissipate heat more effectively under the shift loads these multi-speed units generate, which matters when the stock clutch showed glazing or heat damage as the root cause of the failure.This is a single friction clutch pack, not a kit. It does not include steel plates, seals, gaskets, an Automatic Transmission Filter, or any other transmission components. If your rebuild requires those additional parts, they need to be sourced separately. Ordering the right individual component avoids receiving parts you do not need and keeps your parts list accurate to the job.The part weighs 2 lb and is intended strictly for 10L80 and 10L90 units built in 2017 or later. Before placing the order, cross-reference your transmission identification code and confirm the model year falls within that range. The clutch pack position and quantity required should also be verified against your rebuild specification, since not every clutch pack location in these units uses the same count or configuration.SKU corresponds to this specific friction unit within the 10L80 and 10L90 parts line.
