Seal kit plus 6 friction plates and 6 steel plates for rebuilding the Aisin K114 CVT in 2014-up Toyota RAV4 and Lexus NX200 2.0L models.
Owners and shops working on a 2.0L Toyota RAV4 or Lexus NX200 with the Aisin K114 CVT usually find this kit after one of three complaints: the car takes too long to grab Drive or Reverse, engine speed flares as it pulls away, or fluid is dripping from more than one seal. This is a soft-parts kit for that overhaul. In the box is one complete K114 transmission seal kit, six friction plates and six steel plates.
Ratio changes in the K114 happen in the steel belt and the two variable pulleys, but direction is chosen by two wet clutch packs, one for forward and one for reverse, that sit between the torque converter and the primary pulley. Toyota's service manual for the K114 shows solenoid SLU applying those clutches through engagement, while solenoids SLP and SLS hold primary and secondary pulley pressure to clamp the belt. An oil pressure sensor reports that clamp pressure back to the ECM.
The six frictions and six steels are the wear surfaces of those two packs. The seal kit covers the parts that keep the hydraulics honest: the piston seals and sealing rings on the rotating shafts, the case and passage O-rings, the external lip seals and the pan gasket. A leaking pulley sealing ring lets clamp pressure fall, and the belt starts to slip and whine. A leaking clutch piston seal lets the pack fill late. Replacing both sides together is what restores engagement and pulley clamping at the same time.
A soft-parts rebuild only helps if the hard parts are healthy. Before you order, check fluid level at the overflow plug, since the K114 has no dipstick. Then pull the pan and look at what is on the magnets: fine dark friction dust fits this kit, while bright steel shavings point to pulley, bearing or belt wear. Once the unit is apart, inspect both pulley faces and the belt for scoring, discoloration or witness marks. If they are damaged, the job needs hard parts too. Our guide to CVT failure patterns shows how those wear modes look, and CVT limp mode causes covers the electrical and pressure faults that can mimic a worn pack.
This kit is listed for the Aisin K114 CVT in the 2014-up Toyota RAV4 2.0L and the Lexus NX200 2.0L. Be aware that 2.0L CVT versions of both vehicles were sold mainly outside North America; US-market RAV4s of that era used a geared automatic, and later 2.0L RAV4s moved to the separate K120 Direct Shift CVT, which this kit does not fit. Read the transaxle tag and confirm it says K114, or send us the year and VIN before ordering. For the US-market 2018-2022 C-HR 2.0L, use the K114 rebuild kit for the C-HR. Other units are on our CVT parts page.
Pulleys, belt, pump and valve body are sold separately.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Most US-market RAV4s from 2014-2018 used a geared automatic, not the K114, and later 2.0L RAV4s use the K120. Confirm the transaxle tag reads K114 or send us the VIN before ordering.
Both service the K114 with six frictions and six steels plus seals. This listing is matched to the RAV4 and NX200 2.0L applications, while the C-HR kit is matched to the 2018-2022 C-HR 2.0L. Order the one listed for your vehicle.
Yes. Pulley clamping force comes from hydraulic pressure. If a pulley sealing ring leaks, pressure drops, the belt slips on the pulley faces and the unit can whine or flare.
Toyota specifies Toyota Genuine CVT Fluid FE for the K114. Use it for pre-soaking the frictions and for the refill.
Yes. Toyota's procedure calls for Reset Memory and the CVT oil pressure calibration with a scan tool when the transaxle assembly is replaced, so the ECM relearns pressure.
