6R80 Input Drum, used and ready to install. Fits the 6R80. Ships fast from the USA.
Searching for a 6R80 input drum usually means the transmission is already on the bench. Common reasons are a cracked housing, scored sealing ring grooves on the shaft, or an F-150, Expedition or Mustang that lost 4th, 5th and 6th. This is a used OEM Ford input drum, interchange 49550C, with the input shaft attached. It is the 6-clutch stepped style with a two-ring shaft and fits the 6R80 and 6R60. It comes with a 1-year warranty and costs far less than a new assembly.
The input shaft takes torque from the converter turbine. In the 6R80 the drum on its end is the housing for the E clutch, which GEARS Magazine lists as applied in 4th, 5th and 6th. The shaft also has to carry oil. The two sealing rings on it run inside the stator support, the stationary sleeve at the back of the pump. They route E clutch apply pressure from the case into the spinning drum. That makes this one part a shaft, an oil passage and a clutch housing at once, and any of those three jobs can fail.
Many 6R80s that lose upper gears never need this part. Ford extended lead frame coverage to 10 years or 150,000 miles under Customer Satisfaction Program 19N01 because of internal wiring faults. Sonnax has also shown that the variable bleed solenoids drift off calibration with age and throw shift timing off. Both can mimic a leaking E circuit. Read the codes, check the lead frame and solenoid body using our 6R80 common problems guide and the F-150 version. On a truck in the covered build range, find out whether the dealer program still applies. If those are good, air-check the E circuit through the case. A whistle or slow bleed with the drum in place points to rings, grooves or the support. Leakage only with the drum out on the bench points to the piston or housing.
This 49550C drum is listed for both the 6R60 and the 6R80. Compare it to your old part on three points: two sealing rings on the shaft, the stepped housing, and room for six frictions. If yours differs, or the old drum is gone, send us the year and VIN and we will check it first. See every hard part for this unit on our 6R80 transmission page.
Always fit new sealing rings on the shaft and size them gently so they do not snag the stator support. Inspect that support bore closely. If it is grooved, a replacement front pump such as the 6R80 pump brings a fresh support with it. Fit new E piston seals, frictions and steels. The 6R80 overhaul kit supplies the seals. Air-check E on the bench and again after assembly. If the truck had lead frame codes, replace it during the same job with the 6R80 lead frame kit, which includes a connector and filter. Fill with Mercon LV, clear adaptives, and complete the relearn drive cycle.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. This 49550C part is the overdrive E clutch drum with its input shaft, the two-ring version.
Yes, input drum and overdrive E drum are two names for this assembly. It holds the E clutch that works in 4th, 5th and 6th.
Air-check the E circuit with the drum installed and again on the bench. Leakage only when installed points to the shaft rings, grooves or stator support. Leakage on the bench points to the piston or housing.
Often, yes. Ford extended lead frame coverage under program 19N01, and a failing lead frame or solenoid can mimic an E clutch leak. Check codes and wiring before buying hard parts.
New shaft sealing rings, E piston seals, frictions and steels at minimum. Replace the stator support or pump if its bore is grooved, and use Mercon LV fluid.
