Honda CVT valve body, part 27000-5T0-A01, for 2014-2018 Civic, 2015-2019 Fit and 2016-2018 HR-V. Cures judder and slipping from bore wear.
If your 2014-2018 Civic, 2015-2019 Fit or 2016-2018 HR-V judders pulling away from a stop, flares or feels rubbery on light throttle, or has developed a hard shudder under load, the CVT valve body is the usual cause once a fluid change no longer helps. This is a replacement valve body cross-referenced to Honda 27000-5T0-A01, 27000-5T0-A02 and 27000-5T0-A03 - the A01/A02/A03 suffixes are supersessions of the same casting, so any of the three stamped on your old unit is the correct match for this listing.
The valve body is the hydraulic control center of the transaxle. It routes line pressure through a set of precision bores and spool valves to apply the start clutch and control the pulley ratio, and it carries the shift and pressure-control solenoids the TCM uses to manage that pressure in real time. On this generation of Honda CVT, the part that wears first is the start clutch pressure control circuit - the bore that meters how hard the start clutch engages when you pull away from a stop.
Fresh Honda HCF-2 and a drain-and-fill can mask this for a few thousand miles, since fluid shear temporarily restores some clamping pressure in the worn bore. If the judder comes back a few thousand miles later, that is the signature of bore wear rather than tired fluid, and the valve body is the fix rather than another fluid change.
Scan for stored codes and note whether the judder happens only from a stop (start clutch circuit) or also while cruising (pulley ratio or lock-up circuit), since that changes which bore is worn. Our Honda CVT maintenance guide covers the fluid-change burnishing test that separates a bore-wear judder from a fluid problem, and our CVT harsh and delayed shift guide covers the broader symptom set if your complaint is a flare or a slow upshift instead of a stop-and-go judder.
This valve body is built for the 27000-5T0-A01/A02/A03 casting as used in the 2014-2018 Civic (2-door LX, 4-door EX), 2015-2019 Fit 5-door EX and 2016-2018 HR-V 5-door EX. Honda's own parts catalog lists 27000-5T0-A04 as the current supersession for all three earlier numbers, so if your unit is stamped A04 it is the same part under a newer number. Read the number stamped on your old valve body rather than going by model year alone - the Civic changed CVT hardware partway through this generation, and the earlier and later bodies are not interchangeable. If your car is a newer 1.5L Civic or CR-V, see our 27000-5LJ-014 listing, and if it is a 2016-2024 1.5T Civic or CR-V, see 27000-5X9-014 instead.
Drain the transaxle, pull the pan and filter, unplug the solenoid connectors, then unbolt the valve body evenly and transfer over any solenoids you are reusing. Replace the filter and pan gasket at the same time so debris from the old unit does not circulate through the new one, and torque the bolts in the factory sequence rather than corner to corner. Refill with genuine Honda HCF-2 fluid only - conventional CVT fluid does not have the correct friction properties for this belt-and-pulley design and will bring the judder right back. Let the TCM relearn the start clutch and pulley pressures over several miles of mixed driving, including some stop-and-go, before judging whether the judder is fully gone. For the full written procedure and torque sequence, our valve body inspection and install guide walks through the bolt pattern and common mistakes on electronically controlled units like this one.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
They are the same casting through a series of supersessions. Read the number stamped on your old valve body: A01, A02 or A03 all match this listing, and Honda's current replacement number A04 is the same part under a newer number.
Low-speed judder pulling away from a stop, a flare or rubbery feel on light acceleration, or a shudder under load that returns a few thousand miles after a fluid change all point to a worn valve body bore rather than old fluid.
No. This CVT needs genuine Honda HCF-2. Conventional CVT fluid has different friction properties for the belt and pulley and will bring judder back quickly, even with a new valve body.
It fits the 2014-2018 Civic, 2015-2019 Fit and 2016-2018 HR-V because they share this CVT and valve body casting. Confirm by the part number stamped on your old unit rather than by model year alone.
Yes. Change the filter and pan gasket at the same time, refill with genuine HCF-2, and drive several miles of mixed, stop-and-go driving so the TCM can relearn the start clutch and pulley pressures against the new unit.
No, those use a different casting. See our 27000-5LJ-014 listing for the 1.5L Civic/CR-V or our 27000-5X9-014 listing for the 1.5T Civic/CR-V.
