Frictions, steels, seals and case gasket for a bench overhaul of the Honda M3WC CVT behind the 1.8L Civic, 2014-2016. OE kit ref T14800A.
The 2014 Civic was the first 1.8L Civic to drop the old five-speed automatic for a belt-and-pulley CVT, and those cars are now well past 100,000 miles. If your Civic hesitates going into Drive or Reverse, thumps on engagement, shudders pulling away from a light, or slips and sets a CVT code, the wet clutch packs inside the M3WC transaxle are a common cause. This master rebuild kit (OE kit reference T14800A) carries the friction plates, steel plates, oil seals, O-rings, sealing rings and case gasket to overhaul the clutch and seal side of an M3WC on the bench.
The pulleys and steel push belt change the ratio, but they cannot select direction. Ahead of the pulleys, a forward clutch and a reverse brake are applied by hydraulic pistons to send power forward or backward through a planetary set, and both are wet multi-plate packs bathed in CVT fluid. The kit contains two four-plate friction sets, one paper-faced and one dark composite, plus eight matching steels, which is one full pack for each. Every apply piston depends on its O-rings and the shaft sealing rings feeding it, so a pressure leak at a worn ring slips the pack just like a burnt friction does. That is why the kit replaces the rubber and sealing rings along with the plates.
Check the fluid level and condition first, and confirm the software is current: Honda recalled 2014-2015 Civics under NHTSA recall 15V-574 because the original CVT software used high hydraulic pressure in certain modes that could break a drive pulley shaft, and the fix is a CVT software update. A car that was never updated should be seen by a dealer before anything else. Our CVT harsh or delayed shifts guide walks through engagement timing and pressure checks, and the CVT slipping under load guide helps separate belt and pulley slip from clutch slip. If the belt or pulley faces are scored, this kit alone will not fix it.
This kit is listed for the Honda M3WC CVT in the 1.8L Civic, 2014-2016. In the US the 1.8L CVT Civic sedan and coupe covers 2014-2015; the 2016 North American Civic moved to a new generation with 2.0L and 1.5L turbo engines and different CVTs, so a 2016 car must be checked before ordering. Confirm the transmission code on the case tag reads M3WC, or send us your year and VIN and we will confirm. Other CVT parts are on our CVT collection page.
Lay out each clutch pack in order as you remove it so the new frictions and steels go back in the same sequence, and soak the new frictions in fresh CVT fluid before assembly. Measure pack clearance against the service manual, size the new sealing rings so they are not left stretched, and replace the axle seals while the case is split. The kit does not include the belt, pulleys, valve body, solenoids or filter. Refill only with Honda HCF-2; a generic ATF is not built for the belt and clutch friction demands of this unit. A single quart of genuine HCF-2 is handy for topping off, but a rebuild needs a full fill, so the 12-quart case of HCF-2 covers the refill and the first follow-up service. After reassembly, the CVT learned values should be cleared and relearned with a Honda-capable scan tool.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if it has the M3WC CVT. In North America the 2016 Civic changed to a new generation with 2.0L and 1.5L turbo engines and a different CVT. Check the transmission code on the case tag or send us your VIN before ordering.
Two four-plate friction sets, eight steel plates, the case gasket, axle and shaft oil seals, piston and passage O-rings, and shaft sealing rings. The belt, pulleys, valve body, solenoids and filter are not included.
Not if the frictions are already burned. Fresh HCF-2 can help when the fluid is simply old, but once the friction material is gone the packs have to be replaced.
Yes. NHTSA recall 15V-574 covered 2014-2015 Civic CVT software that could overstress the drive pulley shaft. The remedy is a software update at a Honda dealer, and it should be done before or along with any rebuild.
Honda HCF-2 CVT fluid only. Do not use Honda DW-1 or a universal ATF in this transmission.
Yes. Clear the CVT learned values and run the relearn with a Honda-capable scan tool, then recheck the fluid level at the specified temperature.
