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 'A' or 'H' to confirm the 2.0L engine.
- Physically confirm the vehicle is AWD (presence of rear differential, driveshaft, and transfer case).
- Locate the white barcoded sticker on the original transmission to match part number 45000-3BWV0.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar
- Heavy-duty transmission jack
- OBD-II scan tool with Hyundai/Kia OEM-level bidirectional diagnostic capabilities (GDS)
Budget for these consumables at install:
- Hyundai/Kia Genuine ATF SP-IV (approx. 7.1 to 9.0 quarts)
- Torque Converter Hub Seal (OEM Part Number: 46131-3B600)
- Valve Body Cover Sealant (ThreeBond 1281B or Loctite FMD 546)
- Transmission Filter & Pan Gasket
- Axle Seals
- High-pressure transmission cooler line flush
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Value Reset & Relearn
TCM adaptive values must be cleared using an OEM-level scan tool (GDS or equivalent) to prevent severe shift flares or clutch slippage. A manual stationary and drive relearn procedure must be performed immediately after reset.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque converter must be fully seated (three distinct clicks) to avoid cracking the internal oil pump housing during installation.
- AWD splines must be thoroughly cleaned and greased with high-pressure water-resistant grease to prevent future stripping.
- Plastic level and fill plugs must be handled manually without power tools to prevent cracking.
- Fluid level check must be performed strictly between 50°C and 60°C (122°F-140°F) with the vehicle level and engine running.
- A complete high-pressure flush of the transmission cooler lines is mandatory to prevent contamination from the old unit.
Easy to get right once you know them:
- Ordering a FWD transmission for an AWD vehicle (or vice-versa).
- Reusing the old, contaminated torque converter.
- Skipping the TCM adaptive value reset and relearn procedure.
- Using generic multi-vehicle or older SP-III transmission fluid instead of SP-IV.

- 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

- 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.
