5R110W [03-04] Automatic Transmission Clutch Pack Performance HD Stage 1

Getting the stage 1 clutch pack right in a 5R110W rebuild is not a detail to approximate - the red friction designated for that position has specific surface characteristics matched to how that clutch applies in those early units. This is a single friction pack, stage 1, red, for 5R110W automatic transmission units built in the 2003-2004 range, shipped at 3 lb.

The 5R110W was built with distinct friction specifications across its clutch stages, and substituting across stages or years introduces variables that show up on the road. This part targets stage 1 specifically, which means it is not interchangeable with frictions from other stages in the same unit without verifying the OE specs first.

This listing contains one piece. It does not include steels, additional stage packs, seals, an Automatic Transmission Filter, or a band. If your rebuild requires those components, they need to be sourced separately. Technicians who have pulled the unit and identified stage 1 wear as the repair target will find this listing straightforward. Those still assessing the full scope of work should confirm all needed parts before placing an order.

REMCO has been working in automatic transmissions since 1991. Each order is assembled here, piece by piece, and checked against its part list before it ships. A copy of that list goes in the box.

Application is 5R110W, years 2003-2004. Confirm the transmission code stamped on the unit and verify the build year matches before ordering.

• Clutch slip and delayed engagement in a 5R110W often trace back to a worn stage 1 friction pack - replacing it with the correct part addresses the root cause directly.
• This listing covers one friction pack only. It does not include steels, other stage packs, seals, Automatic Transmission Filters, or bands. Confirm the full scope of your rebuild before ordering.
• Stage 1 positioning in the 5R110W clutch stack is specific: using the red friction designated for that stage keeps clearances and apply feel consistent with the stock design.
• One stage 1 red friction pack, 3 lb. Verify count and condition against the part list included in the box at the time of assembly by REMCO since 1991.
• Before ordering, confirm the transmission code is 5R110W and that the unit was built in the 2003-2004 range. Stage position and year range both matter for correct fitment.
