When a 4F27E, FNR5 or FN4A-EL develops clutch slippage or a burnt apply circuit, replacing the friction clutch pack at the correct stage is the starting point of a clean repair, and this Stage 1 friction pack is cut to the dimensions that position matters for that specific apply circuit. What separates this part from a generic friction disc is that it is sourced and stocked specifically for the 4F27E family, which includes the FNR5 and FN4A-EL designations used across units built from 2000 up to present production.This is a single-piece automatic transmission friction clutch pack covering Stage 1 of the apply circuit. It is not a rebuild kit, a seal kit or a multi-piece set. The listing contains one pack and nothing else, so if your job also calls for steel plates, seals, gaskets, a filter or a band, those need to be sourced separately before you begin the teardown.At roughly 2 lb shipped, this is a straightforward replacement component. The friction material thickness and outside diameter are matched to the Stage 1 position inside the 4F27E bore, so fitment depends on confirming you are working on the correct unit and the correct clutch stack location within it.Before placing the order, pull the transmission code directly from the unit, not from the vehicle identification or a parts catalog cross-reference. Confirm it reads 4F27E, FNR5 or FN4A-EL and that the build year falls at 2000 or later. If the code on your unit does not match one of those three designations, this pack is not the right part for your application. Stage 1 friction clutch pack built to the dimensional spec of the 4F27E, FNR5 and FN4A-EL, addressing slipping and heat damage in the clutch apply circuit without adding unnecessary parts. This listing is for one friction clutch pack only. It does not include steel plates, seals, gaskets, filter, band or any other transmission component. Verify your exact need before ordering. The friction material and dimensions on this pack match the Stage 1 apply circuit of the 4F27E family, which spans the FNR5 and FN4A-EL variants built from 2000 onward, covering a wide range of production years up to present. Contents: 1 friction clutch pack, Stage 1. Item ships at approximately 2 lb. No additional pieces are included inside the package. Before ordering, confirm the transmission code stamped on your unit matches 4F27E, FNR5 or FN4A-EL, and verify the build year falls within the 2000-and-up application range covered by this part.
