K310 Overhaul Kit 2006, new and ready to install. Fits the K310. Ships fast from the USA.
This is the seal and gasket kit for rebuilding a Toyota K310 CVT, the 1.5L-class Super CVT-i unit that went into production in September 2006. If your Allion, Premio, Ractis, Rumion, Corolla Axio or Subaru Trezia is leaking from the case, slow to engage Drive or Reverse when cold, or losing line pressure after high mileage, the rubber and sealing rings inside are the place to start. The kit is a Transtec overhaul kit marked for the K310 2006-up, supplied without pistons and with a Duraprene pan gasket.
The K series moves power through two variable pulleys joined by a steel push belt. Pulley clamping and the forward clutch and reverse brake that select direction are all hydraulic, so every circuit depends on seals and sealing rings holding pressure. When those parts harden or wear, pressure bleeds off, the belt can lose clamping force and the clutches engage late. An overhaul kit replaces the soft parts: case and cover gaskets, O-rings, lip seals and the sealing rings on the rotating shafts. Because this version is listed without pistons, your bonded clutch pistons are reused, so inspect their rubber before deciding this is the right kit.
Check fluid level and condition first; a low level from an external leak can cause many of the same complaints. Scan for stored transmission codes, since a pressure solenoid or valve body fault will not be cured by seals alone. Our CVT slipping under load guide walks through separating belt and pulley wear from hydraulic leaks, and CVT harsh or delayed shifts covers engagement complaints. If the valve body itself is worn, a replacement such as our K310 valve body may be the bigger fix.
The listing is marked K310 2006-up and names these applications: Subaru Trezia 2010-2016 1.5L, Toyota Allion and Premio 2007-2016 1.5L FWD, Auris, Corolla and Porte 2012-2016 1.5L 4WD, Ist 2007-2010 1.8L, Ractis 2010-2016 1.5L, Rumion 2007-2015 1.5L and Wish 2009-2013 1.8L. The K310 shares its basic layout with the K311, K312 and K313, but seal sizes and pistons are not always the same across them, so confirm the transmission code on the case tag or send us your year and VIN before ordering. If your unit is a K313, our K313 master overhaul kit with frictions and steels is the closer match. More parts are on the CVT parts page.

No. It is the overhaul kit only: gaskets, seals, O-rings and sealing rings with a Duraprene pan gasket. Frictions, steels, pistons and the filter are separate.
The bonded clutch pistons are not in the box, so you reuse your originals. That is fine if their rubber is still soft and undamaged; if not, choose a kit with pistons or buy a piston kit.
Not with certainty. The K313 is a later member of the same family and can differ in seal and piston details. Read the code on your transmission tag and match it, or send us your VIN.
Use Toyota CVT Fluid TC unless your owner's manual specifies a different Toyota CVT fluid. Never use conventional ATF in a K310.
Only if the cause is pressure loss from worn seals. A whine from the belt, pulleys or bearings, or a solenoid fault, needs those parts repaired as well.
