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 VIN's 8th digit is for a 2.0L engine (check emissions label under hood).
  • Check original transmission's OEM Part Number on the white barcode sticker to confirm it matches 45000-3B690.
  • Confirm vehicle body style is a 2011-2013 Kia Forte Sedan or Hatchback with 2.0L engine and automatic transmission.
🔎 Where to look: Locate the white barcode sticker on top of the bellhousing, or look for an etched code on the metal case next to the riveted VIN tag starting with 'EA', 'FA', or 'BA'.

What the install really takes — plan and budget with confidence:

5.0-8.0shop labor600-1,400typical shop bill, on top of the partAdvanced / ExpertDIY difficulty

Special tools this job needs:

  • Engine support bar
  • Transmission jack
  • CV axle pry bar/popper
  • Torque wrench
  • Professional OBD-II scan tool / Kia GDS/KDS factory scan tool
🔌 Wiring harness: Transmissions from different model years or platforms feature distinct internal wiring harnesses and solenoid calibrations. Units built after March 2013 integrate the transmission oil temperature sensor directly into the internal wiring harness, whereas earlier versions utilized a separate sensor and harness.

Budget for these consumables at install:

  • Hyundai/Kia ATF SP-IV fluid
  • Torque Converter Seal (Front Pump Seal, OEM part # 45265-3B000 or equivalent)
  • Axle Seals (both sides)
  • Aerosol transmission cooler line flush solvent

What your vehicle’s computers will need after the swap:

⚠️ Requiredprogramming / calibration⚠️ Yesdealer tool needed✅ NoECU/PCM re-marriage

What’s involved: TCM Adaptive Relearn (Static Shift Relearn + Dynamic Drive Relearn)

A TCM adaptive learning reset is mandatory after installation. A professional bi-directional scan tool (such as Kia's factory GDS/KDS tool) is required to clear old adaptive values from the TCM, followed by a specific static and dynamic drive relearn procedure.

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 crushing the internal oil pump.
  • Dowel Pin Alignment: Ensure alignment dowel pins are present and not double-stacked to prevent crooked installation and severe vibrations.
  • Subframe Support: Support the engine from above using a dedicated engine support bar when lowering the subframe.
  • Fluid Level Check Procedure: Check fluid level with engine running, transmission at 122°F to 140°F, vehicle level, using the overflow plug on the front side of the plastic valve body cover (no dipstick).
  • Mandatory Cooler Flush: Debris from the old failed transmission must be flushed out of the radiator cooler and lines to prevent immediate contamination of the replacement unit.
  • Internal Filter: The main filter is internal and located behind the valve body; it cannot be replaced without splitting the case or removing the valve body.

Easy to get right once you know them:

  • Using the wrong fluid (using older SP-III or generic multi-vehicle ATF instead of SP-IV).
  • Failing to flush the transmission cooler lines, leading to immediate contamination and failure.
  • Skipping the TCM adaptive reset, causing violent shifting and physical damage to replacement clutches.
  • Damaging the shifter cable bushing during removal by prying it off improperly.
  • Improper torque converter installation resulting in a cracked front pump during engine mating.

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:

severeTransmission Fluid Cooler Hose Leak2011

🔎 Recommended at install: NHTSA Recall 16V070000 (Kia Recall SC129) - Replace fluid cooler hose to prevent fluid loss and unexpected loss of motive power.

moderateBrake Pedal Stopper Pad Deterioration2013

🔎 Recommended at install: NHTSA Recall 17V823000 (Kia Recall SC139/SC140 Related) - Replace brake pedal stopper pad to prevent shifting out of PARK without depressing the brake pedal.

moderateTransmission Fluid Temperature Sensor Failure2011-2013

🔎 Recommended at install: TSB 13-AT-012-2 - Replace the oil temperature sensor and internal wiring harness (triggers P0711, P0712, or P0713).

moderateShift Harshness & Shudder2011-2013

🔎 Recommended at install: TSB 17-AT-008 - Update TCM software and perform adaptive learning reset.

moderateMandatory Adaptive Value Reset2011 and newer

🔎 Recommended at install: TSB TRANS 049 (TSB_TRA049R1) - Perform mandatory adaptive value reset and relearn procedure after replacement.

moderateIncorrect Fluid Usage2011-2013

🔎 Recommended at install: TSB TRA046_R1 - Follow updated guide on using correct type and quantity of transmission fluid.

moderateGeneral Shifting Issues (Rough shifting, jerking, hesitation)2011-2013

🔎 Recommended at install: Can be traced to faulty shift solenoids or internal failure of the TCM itself (generating false codes P0763, P0758).

Researched from factory recalls, TSBs and OEM service data (reference unit 400-51946-1596612). 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.
