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:
- Verify the 8th digit of the VIN to ensure it is a 1.6L gasoline model.
- Check the driver's side door jamb sticker for production date (fits 2015 models from 09/01/14 and all 2016 models).
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar
- transmission jack
- subframe support/jack
- OBD2 bidirectional scan tool
Budget for these consumables at install:
- Hyundai/Kia SP-IV (SP4) spec fluid
- Plastic front valve body cover gasket (if cover is removed)
- Torque converter hub seal (front pump seal)
- Axle shaft seals (left and right)
- Dedicated aerosol cooler-line flush
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Relearn / Reset
A bidirectional scan tool is required to perform the 'Resetting Auto T/A Values' (Adaptive Reset) and 'TCM Learning' procedure. For some models, the TCM requires entering the transmission's specific oil-pressure calibration values found on the barcode/QR sticker.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: Ensure the torque converter is fully seated (three distinct clicks/drops) before bolting to the engine to avoid cracking the oil pump gear.
- Solenoid Barcode / QR Code Sticker: Take a clear photo of the sticker on the case before installation, as it is extremely difficult to see once installed and is needed for TCM programming.
- Fluid Level Check Procedure: No dipstick. Must check at 50C-60C (122F-140F) with engine running and vehicle level, using the overflow plug on the front plastic cover.
- Subframe Removal: Requires lowering or completely removing the front subframe/cradle while supporting the engine from above.
Easy to get right once you know them:
- Using the Wrong Fluid: Using non-SP-IV fluid causes immediate slipping, harsh shifting, and voids warranty.
- Mismatched Transmission Versions: Attempting to use an A6GF1 from other models like Elantra or Forte which have different mounts, torque converters, and gear ratios.
- Skipping the Adaptive Reset: Driving without resetting TCM adaptive values causes incorrect line pressures, violent shifts, and rapid clutch destruction.
- Forgetting to Flush the Cooler Lines: Reusing old radiator and cooler lines without flushing washes debris and metal shavings into the new unit.

Policies, in plain English.
Shipping & Handling
- Ships by LTL freight on a pallet — a real freight truck, not a parcel van
- 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
120-Day Warranty
This part includes a 120-day warranty.
- If the part fails within the warranty window, we'll replace it or refund per the coverage terms
- Coverage is parts-only — installation labor is not included
- Warranty covers defects — not installation errors, misuse, or damage after installation
Your pre-purchase interview reviews these exact terms with you before anything is charged.
Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.
- Defective parts: We will replace the part or issue a refund at our discretion
- Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
- Return shipping: This part ships by freight (LTL) — the part price is refundable per the terms above, but shipping costs are non-refundable and return freight follows the seller's return terms. Your pre-purchase interview walks through the exact numbers before you buy
- Parts must be returned in original packaging and unmodified condition
- Poorly packaged returns that arrive damaged will not be credited
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.
