6T40 Input Drum 2012-13, used and ready to install. Fits the 6T40. Ships fast from the USA.
This is a used, original GM 4-5-6 input clutch drum assembly removed from a 6T40 out of a 2012-13 Chevrolet Cruze with the 1.4L turbo engine. It is for the builder or DIY rebuilder who has a 2012-13 Cruze 6T40 apart and found the input drum cracked, the lugs notched, or the sealing ring bore scored, and wants a factory part from the same application instead of an expensive new one. It is sold as used, in good clean condition with normal wear, so it should be inspected like any core before it goes in.
The input drum is driven by the turbine shaft, so it spins at input speed any time the engine is pulling the car. It carries the 4-5-6 clutch, which is applied in 4th, 5th and 6th, and it supplies input torque to the gearset through that clutch. Because it turns constantly, the drum also rides on sealing rings and a bushing that feed apply oil to its piston. Worn ring grooves or a scored bore leak that oil away, the clutch apply pressure drops, and the pack slips. The input speed sensor on the 6T40 reads a rotating clutch assembly, so a damaged drum can also upset the speed signal the TCM uses to judge ratio and slip.
A 2012-13 Cruze is a Gen 2 6T40, so solenoids and the control module are part of every top-gear complaint. Read the codes and freeze-frame data, check fluid level hot, and look at the input and output speed data on a scan tool. Our 6T40 speed sensor symptoms guide explains how to tell a bad sensor from a slipping clutch, and the shift solenoid guide covers the Gen 2 solenoid tests. If the pan shows metal and the pattern stays at 4th-5th-6th, it is time to pull the unit.
This drum came out of a 2012-13 Cruze 1.4L 6T40, which is a direct match for that car and those model years. Other 6T40 applications from the same period may use the same drum, but GM made running changes, so check the part against your original before installing: compare the lug count, the overall height, the spline and the shaft end, and look for any casting or stamped numbers. If you have a different vehicle or year, send us the year and VIN first. If you would rather install a new part, the 6T40 clutch drum for 2012-2021 covers the same era.
Because this is a used part, inspect it on the bench: look over the lugs for notching, check the bushing for wear, check the sealing ring grooves for steps or burrs, and fit new sealing rings. Install a new piston and seals, plus new frictions and steels, and set 4-5-6 clutch clearance to spec. Air-check the clutch on the bench before the drum goes into the case. The 6T40 overhaul kit for 2012 covers the soft parts, and the 6T40E rebuild kit with pistons and filter adds new bonded pistons, which GEARS recommends replacing on every rebuild. Refill with Dexron VI, set the level hot at the check plug, then clear adapts so the TCM can relearn shift timing.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Used. It is an original GM part removed from a 2012-13 Cruze 1.4L 6T40 and is in good clean condition with normal wear. Inspect the lugs, bushing and sealing ring grooves before installing, and fit new sealing rings.
It is a direct match for the 2012-13 Cruze 1.4L 6T40. Other 6T40 vehicles may use the same drum, but compare your original's lug count, height and shaft end, or send us your year and VIN before you order.
It can upset the signal, because the 6T40 input speed sensor reads a rotating clutch assembly. Test the sensor and wiring first; if those are good and top gears slip, the drum and 4-5-6 clutch are next.
Yes. Install a new piston and seals, new sealing rings, and new frictions and steels for the 4-5-6 pack. Reusing old soft parts on a replacement drum is a common cause of repeat slips.
Dexron VI, with the level set hot at the level set plug. GM lists a fluid change capacity of roughly 4.2 to 6.3 quarts for the 6T40.
