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 is 6 (designating the 2.4L engine).
- Confirm the vehicle is All-Wheel Drive (AWD) by checking for a rear driveshaft and rear differential.
- Locate the barcode sticker or etched code on the original transmission case and confirm the model code begins with FD (AWD) rather than FB (FWD).
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar
- Subframe jack or jack stands
- Transmission jack
- Professional-level bidirectional scan tool
Budget for these consumables at install:
- Kia/Hyundai SP-IV (SP-4) automatic transmission fluid (7.1 to 7.8 quarts for dry fill)
- Torque converter seal (front pump seal)
- Axle/transfer case output shaft seals
- Plastic side cover (valve body cover) gasket (if cover is removed)
- Professional-grade transmission cooler-line flush
- High-pressure, water-resistant spline grease
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Relearn AND Oil Pressure Characteristic Values Input (Barcode/QR Programming)
Requires a dealer-level Kia Diagnostic System (KDS) or high-end bidirectional scan tool to clear old adaptive values, perform the adaptive reset, and program the 68-digit oil pressure characteristic code from the barcode sticker. A dynamic road test relearn procedure (TSB TRA 049) must also be performed.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Photograph the barcode/QR sticker on top of the transmission case before installation, as it is completely hidden once installed.
- Ensure the torque converter is fully seated onto the pump splines (clicking and dropping back three distinct times) before bolting to the engine to avoid cracking the internal oil pump.
- Liberally grease the AWD output splines with high-pressure water-resistant grease to prevent rusting and stripping.
- Strict fluid level check procedure: check with vehicle level, engine idling in Park, fluid temperature at 122-140 degrees F (50-60 degrees C) via scan tool, and check overflow plug on the plastic side cover.
- Ensure alignment dowel pins between the engine block and transmission bellhousing are clean and in place.
Easy to get right once you know them:
- Ordering a FWD transmission (model code FB) instead of AWD (model code FD).
- Skipping the 68-digit barcode programming or TCM adaptive relearn procedure.
- Using generic multi-vehicle ATF instead of genuine SP-IV fluid.
- Not cleaning and greasing the AWD splines during installation.
- Failing to flush the transmission cooler lines, leading to immediate contamination from the failed unit.
- Forcing the torque converter into place and breaking the front pump.

- 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

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.
