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 '5' (confirming the 2.0L Nu engine).
- Confirm vehicle has 17-inch wheels (tire size P215/55R17).
- Locate the white barcode sticker on top of the transmission case and verify OEM part number 45000-2F755.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar
- Transmission jack
- OEM-compatible bi-directional scan tool (Kia GDS/KDS)
Budget for these consumables at install:
- Hyundai/Kia ATF SP-IV fluid
- High-temperature RTV silicone sealant (Ultra Gray)
- Front pump/torque converter input shaft seal (OEM 46131-3B600 or National 710615)
- Axle seals
- Professional-grade transmission cooler-line flush
What your vehicle’s computers will need after the swap:
What’s involved: Oil Pressure Characteristics Input & TCM Adaptive Relearn
Must scan/input QR code serial digits from the case sticker into the TCM and perform an adaptive values reset using a Kia GDS/KDS or equivalent professional scan tool.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque converter must be spun and pushed to click/drop three distinct times to fully seat (recessed 11-12mm) before bolting to engine to avoid crushing the oil pump.
- Take a high-resolution photo of the barcode/QR code sticker on top of the case before installation, as it will be completely blocked by the battery tray and air cleaner once installed.
- Ensure both alignment dowel pins are present in the engine block to prevent off-center mounting, vibrations, and seal leaks.
- Fluid level must be checked via the front overflow plug on the plastic valve body cover with the vehicle level, engine idling, and fluid temperature at 122-140°F (50-60°C).
Easy to get right once you know them:
- Reusing the old contaminated torque converter, which voids the warranty.
- Using generic Dexron or multi-vehicle ATF instead of genuine SP-IV fluid.
- Using bellhousing bolts to force the engine and transmission together when the converter is not fully seated.
- Skipping the mandatory TCM calibration/adaptive relearn step.
- Ordering this unit for a Soul with 16-inch or 18-inch wheels.
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: Write unique barcode/QR code calibration data to the TCM using a dealer-level scan tool.
🔎 Recommended at install: Inspect internal bolts; low-mileage units are less prone but should be verified.
🔎 Recommended at install: Replace internal plastic ribbon harness.
🔎 Recommended at install: Install updated internal harness with integrated robust sensor.

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

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

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

- 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.
