Complete friction, steel plate, gasket and seal overhaul kit for the Hyundai and Kia A6MF1/A6MF2 six-speed automatic, 2.0L to 3.5L, 2010 and up.
When an A6MF1 or A6MF2 starts flaring between gears, bangs on the 6-4 kickdown or comes out with burnt clutches, a valve body or solenoid kit will not fix it. This master overhaul kit is for a full rebuild of the Hyundai/Kia six-speed in the 2010-and-up Sonata, Santa Fe, Tucson, Azera and Veloster and the Kia Optima, Sorento, Sportage and Cadenza. It includes the friction clutch plates, steel reaction plates and the full overhaul gasket and seal set for the case, pump and clutch drums. It replaces service kit numbers B260820A, B260880A and W260881A.
The A6MF is Hyundai/Kia's own transverse six-speed. It uses underdrive (UD), overdrive (OD), 2-6, 3-5-Reverse and Low/Reverse friction elements, all controlled by two on/off solenoids and six PWM solenoids. Each friction element is applied in more than one gear, so one burnt pack can cause flares or slipping on several shifts. This kit replaces all of the plates and every rubber seal and gasket that holds clutch apply pressure.
TransGo lists the flares, the 6-4 bang, solenoid performance codes and TCC shudder as common complaints on this family. Many of these start in the valve body. The two reducing valves wear their bores, which changes the feed pressure to all eight solenoids. A TCC control valve bushing can also wear and weaken lockup apply. If the fluid is clean, check line pressure and solenoid feed first, using our guides on reading transmission live data and flare vs. slip. Transmission Digest also documented a 2011 Kia Forte A6MF1 that burned only its L/R clutch. A broken tab on the solenoid retainer bracket let shift solenoid A pop out of place, so the L/R brake applied on the 3-4 shift. If you find one burnt pack, find out why before you rebuild.
The listing covers 2010-and-up front-wheel-drive and AWD Hyundai and Kia models with the A6MF1 or A6MF2 and 2.0L to 3.5L engines. Model years and engines changed often across these lines, and some models used the related A6LF transmission instead. Check the ID tag on the case and match it to an A6MF code or to service kit B260820A, B260880A or W260881A before you order. For an A6LF1 unit, use the separate A6LF1 master rebuild kit. If you are unsure, send us the year and VIN. Other parts are under transmission rebuild kits.
The kit does not include hard parts, the valve body, solenoids or the torque converter. If your unit had solenoid codes before it failed, install a new A6MF1 eight-piece solenoid kit during the rebuild. Flush the cooler and clear adaptive values with a scan tool after installation.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2010-and-up FWD and AWD Hyundai and Kia models with the A6MF1 or A6MF2 and 2.0L to 3.5L engines, including the Sonata, Santa Fe, Tucson, Azera, Veloster, Optima, Sorento, Sportage and Cadenza. Confirm the transmission code on the case tag, because some trims used the A6LF.
Friction plates, steel plates and the complete overhaul gasket and seal set for the case, pump and drums. It does not include hard parts, the valve body, solenoids or the torque converter.
No. Use Hyundai/Kia SP-IV specification fluid. Shift timing on this transmission depends on the friction characteristics of the correct fluid.
Not always. The 6-4 bang is often caused by worn reducing valve bores in the valve body. If the fluid is clean and there is no slipping, start with the valve body. Rebuild the transmission when the clutches are burnt or slipping.
Yes. Clear the stored shift adaptive values with a scan tool and drive through a relearn so the new clutches apply correctly.
