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 VIN and confirm vehicle is Front-Wheel Drive (FWD) with no rear driveshaft or rear differential.
- Confirm engine is the 3.3L V6 (check emissions label or 8th digit of VIN).
- Locate the barcode label on top of the transmission case and verify OEM part number 45000-3BGG0.
- Verify the etched case code next to the barcode begins with 'BA'.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar or heavy-duty transmission jack
- Professional scan tool (Kia GDS/KDS or equivalent bi-directional tool)
- Torque wrench
- Fluid pump or suction gun
Budget for these consumables at install:
- Hyundai/Kia Genuine ATF SP-IV (SP-4) fluid (7.8 to 8.2 Quarts / 7.8 Liters)
- New plastic side cover gasket (if inspecting valve body)
- New internal oil filter (requires case split, typically pre-installed)
- New front pump / torque converter seal
- New axle shaft seals
- Professional aerosol transmission cooler flush (e.g., Lubegard Kooler Kleen)
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Value Reset and Relearn
A dealer-level scan tool (Kia GDS/KDS or high-end equivalent) is required to clear the old transmission's adaptive memory. A specific drive-cycle relearn must then be performed. Failure to do so will cause severe shift shocks and premature clutch failure.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: Must feel three distinct clicks/drops to ensure it is fully seated on the input shaft and pump gears. Failing to do so will crush the internal oil pump upon bolting to the engine.
- Fluid Fill and Level Check: No dipstick. Must fill through top plug, run through gears, monitor TFT via scan tool until it reaches 122-140 deg F (50-60 deg C), and check level via the overflow plug on the side cover.
- Cooler & Line Flush: Debris from the failed unit must be completely flushed out to prevent immediate contamination and warranty voiding.
- Crankshaft Position Sensor: Located near the top of the bellhousing and is easily damaged during removal/installation.
Easy to get right once you know them:
- Ordering FWD instead of AWD or vice versa (must physically check for rear driveshaft/differential).
- Skipping the TCM adaptive relearn procedure before driving.
- Using incorrect fluid (using SP-III or generic Dexron VI instead of SP-IV).
- Reusing the old front pump seal.
- Improper torque converter installation leading to cracked pump gears.
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: Dealer must replace the shifter interlock mechanism to prevent unintended rollaway.
🔎 Recommended at install: Replace individual faulty solenoids on the valve body (DTCs P0741, P0743, P0748, etc.) rather than the entire transmission.
🔎 Recommended at install: Install the updated one-piece internal wiring harness with integrated sensor (OEM part 46386-3B900) to resolve DTCs P0711, P0712, or P0713.
🔎 Recommended at install: Replace the front pump/torque converter seal prior to installation to prevent rapid fluid loss and clutch destruction.
🔎 Recommended at install: Inspect front axle integrity on this vehicle platform.
Researched from factory recalls, TSBs and OEM service data (reference unit 400-62710-4334176). Unit-specific details — mileage, condition, warranty, freight — are covered in the checkout interview.
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.
