Know This Transmission Before You Buy
The research behind our purchase interview — recalls, bulletins and real install economics for this transmission family:
A quick look at your own vehicle makes sure the right transmission shows up:
- Confirm engine size is 1.6L (Turbocharged for A6MF2)
- Confirm body style is Coupe (Koup) or Hatchback (Forte5)
- Locate transmission tag near shifter linkage to verify model code and OE part number
- Check case etching to see if serial number starts with EA, FA, or NA
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar
- Transmission jack
- Professional bidirectional scan tool
Budget for these consumables at install:
- Kia Genuine ATF SP-IV (or compatible synthetic fluid meeting SP-IV specifications)
- RTV silicone (high-quality ultra-grey for plastic side cover)
- Front pump/torque converter seal (OE Part Number: 46131-3B600)
- Transmission cooler-line flush aerosol or machine
- Axle seals
What your vehicle’s computers will need after the swap:
What’s involved: Solenoid Oil Pressure Characteristic Value Input (Data Transfer) AND Transmission Control Module (TCM) Adaptive Relearn
Requires inputting the unique barcode/QR code values from the sticker on top of the replacement transmission case into the vehicle's computer to calibrate hydraulic tolerances, followed by clearing the old adaptive learning history and performing a stationary/driving relearn procedure.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: Must click into place three times to fully seat. If not fully seated, bolting to the engine will instantly crush and crack the internal oil pump.
- Solenoid Barcode Sticker: Do not paint over, damage, or remove the barcode/QR code sticker on top of the transmission case.
- Fluid Level Check Procedure: No dipstick. Must check via level-check plug on the side of the plastic valve body cover with fluid at 122-140 degrees F (50-60 degrees C) while engine is idling in Park.
- Bellhousing Alignment Dowels: Ensure engine block alignment dowels are in place and undamaged to prevent input shaft binding and leaks.
- Plastic Pan Caution: Plastic oil pan can crack if the drain plug or pan bolts are over-torqued.
Easy to get right once you know them:
- Ordering for a Non-Turbo Model: Confusing the 1.6L Turbo transmission (A6MF2) with standard 1.8L or 2.0L non-turbo transmissions.
- Skipping the Solenoid Programming: Driving without inputting solenoid characteristic barcode values or resetting adaptive learning, leading to immediate violent shifting and clutch burnout.
- Neglecting the Cooler Flush: Reusing the existing transmission cooler and lines without a thorough flush, introducing debris into the replacement unit.
- Incorrect Fluid Level Check: Checking fluid level when cold or with the engine off, leading to severe underfill or overfill.
- Using the Wrong Fluid: Using non-SP-IV compatible multi-vehicle ATF.
Not issues with the units on this page — the manufacturer documented these for every transmission of this family, wherever you buy one. Handy for your installer:
🔎 Recommended at install: Program/write unique solenoid characteristic values printed as a barcode/QR code on top of the transmission case into the vehicle's computer using a dealer-level scan tool.
🔎 Recommended at install: Reset computer's adaptive learning values and perform a specific driving relearn procedure.
🔎 Recommended at install: Address wear in reducing valve bores and pressure control solenoids to resolve slipping or harsh shifts.
🔎 Recommended at install: Carefully inspect the case and mount area of the donor unit; avoid bottoming out.
🔎 Recommended at install: Replace with updated harness that integrates the temperature sensor directly into the ribbon cable.
🔎 Recommended at install: Refer to guide for correct fluid type and fill quantity to prevent service errors.
🔎 Recommended at install: Mandatory software update to the Engine Control Unit (ECU).
🔎 Recommended at install: Be aware of ABS module internal leaks causing electrical shorts.

- Your checkout freight quote covers delivery to your door (liftgate service included for residential addresses)
- The carrier calls ahead to schedule a delivery window — someone must be present to receive it
- Typically palletized and picked up within 2–3 business days; transit time depends on distance

Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.

Damaged in Shipping?
Freight damage is rare — and you're fully protected when you do two things at delivery:
- Inspect before you sign — you're allowed time to look the pallet over while the driver waits
- Write any damage on the delivery receipt before signing — that one line is what makes a freight claim succeed
- Severe damage? Refuse the delivery — it goes back at no cost to you and we make it right
- Photograph the pallet before unwrapping; report concealed damage within 24 hours of delivery
We handle the carrier claim — you just help document it. Your pre-purchase interview walks through this checklist too.
Order Cancellation
Cancel before shipment for a full refund. Once the pallet has been built, a preparation charge may apply — and once the freight carrier picks it up, shipping costs are non-refundable and standard return terms apply. Your pre-purchase interview shows the exact numbers before you pay.
