4R70W Clutch Module 1980, new and ready to install. Fits the 4R70W. Ships fast from the USA.
This is not a stock rebuild pack. It is the Raybestos GEN 2 Blue Plate Special friction module, part number RCPBP-35, built for Ford AODE and 4R70W transmissions that are going behind a supercharged Mustang, a built Panther-platform drag car, or a truck making far more power than Ford ever planned for. Raybestos catalogs it as 1980-on because the forward plate it uses dates back to the original AOD, which is why the year in our title reads 1980. If you are chasing slipping on the 2-3 shift, burned direct clutches after adding power, or a soft 1-2 that will not hold on the launch, this is the friction set racers put in when the stock material is the weak link.
The 4R70W runs a Ravigneaux gearset with ratios of 2.84, 1.55, 1.00 and 0.70 in overdrive. Second gear comes from the intermediate clutch, third from the direct clutch, and the forward clutch drives the gearset in the first three ranges. Those three packs take the shift energy on every upshift, and the direct clutch is the one that usually fails first in modified cars. RCPBP-35 replaces exactly those positions with GEN 2 Blue race material:
Raybestos rates the material for serious racing use and says it gives its biggest benefit in dynamic positions, the clutches that apply during a shift rather than holding from a stop. Steels are not included.
Burned clutches in this family are often the result, not the root problem. Low line pressure from a worn pressure regulator bore, a weak EPC signal, a blown accumulator, or a cracked direct drum will kill new frictions just as fast. Check pressure with a gauge and inspect the direct drum splines and stub shaft before you order. Our 4R70W 3-4 clutch failure guide covers those causes, and the Crown Victoria shift problems guide lists the valve body faults that cook clutches.
Raybestos lists RCPBP-35 for Ford AODE and 4R70W units, 1980-on. In practice that means the AODE and the 4R70W found in Mustangs, Crown Victorias, Grand Marquis, Town Cars, F-150s, Expeditions and E-Series vans. Clutch counts can change with drum style and with performance drums that hold extra plates, so count your plates at teardown and check clearances. For a stock-power daily driver the Raybestos HT 4R70W friction module is the better value. Send your year and VIN if you are unsure, and see the full range on our 4R70W parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Raybestos catalogs the pack as AODE/4R70W 1980-on because its forward clutch plate goes back to the original AOD. It fits AODE and 4R70W units, not a 1980 vehicle specifically.
Nineteen GEN 2 Blue frictions: 6 direct, 4 intermediate and 9 forward. No steels, seals or gaskets are included.
Usually not. Raybestos recommends it for serious racing. A stock F-150 or Crown Victoria is better served by an OE-style HT friction module.
Replace piston seals, check steels for heat damage, verify line pressure, and inspect the direct drum and stub shaft. Weak pressure or a cracked drum will burn the new pack.
Use the MERCON V fluid Ford specifies for the 4R70W, and soak the frictions in it before assembly.
