Product Details

The McLeod 88109K is a complete performance automatic transmission rebuild kit designed for the Ford 4R100 four-wheel-drive transmission (1998 and up). Developed through McLeod's collaboration with Raybestos Powertrain — one of the world's largest manufacturers of transmission friction products — this kit delivers a true one-stop-shop solution for a thorough, high-performance transmission overhaul.

What's Included:

  • Stage-1 Friction Clutch Pack — OEM-thickness grooved friction plates for increased holding capacity
  • Steel Clutch Pack — Kolene-treated steel plates to resist warping under heat and high load
  • Transmission Deep Pan Filter — Brass construction for superior fluid flow and filtration
  • Bands (2) — 100% new bands for reliable, fresh engagement
  • Thrust Washer Kit — Full set for proper clearances throughout the rebuild
  • Bushing Kit — Complete bushing set for restored tolerances
  • Performance Overhaul Kit — Includes National Oil seals and FarPak gaskets for superior sealing, plus PTFE-coated rings for tighter seals

Key Features:

  • Kolene steel plates prevent warping caused by heat and high-torque loads
  • PTFE (Teflon) coated rings provide tighter seals and extended service life
  • National Oil seals and FarPak gaskets deliver reliable, leak-free sealing
  • OEM-thickness grooved friction plates maximize clutch pack holding capacity
  • Brass deep pan filter ensures better fluid flow and filtration versus standard filters
  • Rated for up to 500 HP — suitable for high-performance street and towing applications
  • All-new components throughout — nothing remanufactured or reused

The McLeod 88109K automatic transmission rebuild kit is backed by the combined engineering expertise of McLeod Racing and Raybestos Powertrain, giving builders confidence that every component meets performance and durability standards. This kit is designed for the Ford 4R100 4WD automatic transmission used in 1998 and later Ford trucks, vans, and SUVs.
