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 'C' (naturally aspirated 2.4L engine).
- Confirm the vehicle is FWD by checking for the absence of a rear driveshaft and rear differential.
- Verify the OEM part number on the current transmission barcode sticker is 450003F810.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar
- Heavy-duty transmission jack
- Professional-grade diagnostic scan tool (KDS/GDS)
- 24mm socket
Budget for these consumables at install:
- Kia ATF SP-IV (or SP4M-1) fluid
- Torque converter seal (front pump seal, OEM # 46131-3B000)
- Axle seals
- Drain plug and level plug gaskets/washers
- Transmission cooler line flush solvent
What your vehicle’s computers will need after the swap:
What’s involved: TCM Solenoid Barcode Data Transfer & Adaptive Relearn
The 12-digit or 13-digit solenoid calibration code on the case barcode sticker must be programmed into the TCU using a Kia KDS/GDS scan tool. A TCM adaptive memory reset and relearn procedure must also be performed.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque converter must be fully seated into the front pump before bolting to the engine to prevent crushing the pump.
- Photograph the barcode sticker on top of the transmission before installation, as it will be hidden once installed.
- Subframe alignment is critical during reinstallation to prevent steering wheel offset.
- Fluid level must be checked without a dipstick, using the overflow plug at operating temperature (122-140°F) with the engine idling.
Easy to get right once you know them:
- Ordering a FWD transmission for an AWD vehicle or vice versa.
- Skipping the solenoid barcode programming, leading to immediate shift shock and clutch damage.
- Using generic, non-SP-IV specification transmission fluid.
- Failing to flush the transmission cooler lines, which recirculates debris from the failed unit.
- Reusing the old torque converter seal.

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.
