P0741 on Kia by model: symptoms, diagnosis and fix
The 6-speed dual-clutch transmission (DCT) in the 1st generation Niro Hybrid (2017-2022) develops a juddering or shaking sensation when starting from a stop and during low-speed gear changes. The dry clutch pack wears and develops uneven friction surfaces, causing the shudder. This is most noticeable in stop-and-go traffic and typically appears between 25,000-40,000 miles. The issue is exacerbated by the frequent clutch engagement/disengagement required by the hybrid system.
Common Symptoms
- Shuddering when pulling away from stops
- Vibration during low-speed gear changes (1st to 2nd)
- Jerky movement in stop-and-go traffic
- Rough transition between electric and gas power
- Clutch chatter noise at low speeds
How to Fix
Have dealer perform TCU software update (improves clutch engagement mapping). If shudder persists, clutch pack replacement under powertrain warranty ($1,500-3,000). DCT clutch teaching procedure (re-learn) after any clutch service. Some owners report improvement after a complete DCT fluid change with genuine Kia DCT fluid.

Owner tips & cautions
- TipAvoid riding the brake while the car creeps forward in traffic. Either hold the brake firmly or let the car roll. Half-braking causes excessive clutch slip and accelerates wear
- TipRequest the dealer perform a DCT clutch teaching procedure after any software update or clutch service. This calibrates the clutch engagement points
The 2015-2021 Sedona with the 6-speed automatic transmission develops shuddering during gear changes, harsh shifts, and delayed engagement. The torque converter lock-up clutch wears prematurely, and the transmission valve body develops stuck solenoids. Kia released multiple TCU software updates to improve shift quality. In severe cases, torque converter or complete transmission replacement is needed.
Common Symptoms
- Shuddering during 2-3 and 3-4 gear changes
- Harsh or jerky downshifts
- Delayed engagement when shifting from Park to Drive
- Transmission slipping under load (uphill, towing)
- Check engine light with transmission codes
How to Fix
Start with TCU software update at dealer (often free under goodwill). If shudder persists, transmission fluid flush with Kia SP-IV ATF may help. Torque converter replacement ($1,200-2,500) for shudder. Valve body replacement ($800-1,500) for shift quality issues. Complete transmission replacement ($3,500-5,500) for severe cases.

Owner tips & cautions
- TipChange transmission fluid every 30,000 miles with Kia SP-IV ATF. Many Sedona transmission failures are linked to neglected fluid changes
The 8-speed wet dual-clutch transmission in the Stinger exhibits harsh low-speed shifts, delayed response when pulling away from stops, and occasional gear hunting on hills. The DCT clutch pack adapts over time but the adaptive learning can drift, leading to rough shifts. TCU software updates have improved shift quality. In rare cases, clutch pack replacement is needed.
Common Symptoms
- Jerky or harsh shifts at low speeds (1st to 2nd, 2nd to 3rd)
- Delayed engagement when pulling away from a stop
- Transmission gear hunting on inclines
- Shudder during low-speed creeping in traffic
- High RPMs before upshift during normal driving
How to Fix
Have dealer perform TCU software update with latest calibration. A TCU reset (battery disconnect for 30 minutes, then re-learn drive) can recalibrate shift points. DCT fluid change at 30,000-mile intervals with Kia DCT fluid. For severe cases, clutch pack replacement under warranty ($2,000-4,000).
Owner tips & cautions
- TipAfter a TCU update, the transmission needs 200-300 miles of mixed driving to fully re-learn your driving style. Give it time before judging the results
- TipChange DCT fluid every 30,000 miles. Many owners report noticeably smoother shifts after a fluid change with fresh Kia DCT fluid
The 5-speed automatic transmission in the Kia Amanti is prone to premature failure, particularly affecting the torque converter, forward clutch pack, and valve body. The transmission was shared with the Hyundai XG350 platform and struggles with the 3.5L V6 engine torque output. Symptoms progress from harsh shifting to slipping to complete failure, typically between 80,000-120,000 miles. Regular ATF changes can extend life, but the transmission design has inherent durability limitations.
Common Symptoms
- Harsh or delayed shifts
- Transmission slipping under acceleration
- Shudder during gear changes
- Loss of forward or reverse gears
- Check engine light with transmission codes

The YD-generation Forte's conventional six-speed automatic (A6GF1 behind the 1.8/2.0 Nu, A6MF2 behind the 1.6T) wears the aluminium valve-body bores that carry the two pressure-reducing valves and the torque-converter-clutch control valve. As the bores egg out, solenoid feed pressure becomes unstable: line pressure control goes off, upshifts flare or momentarily neutral, the 6-4 kickdown lands as a bang, and torque-converter lockup applies harshly or shudders at light throttle around 40-50 mph. It sets TCC-circuit and pressure codes rather than a hard failure code. This is a hydraulic wear failure of the torque-converter automatic and must not be confused with the BD-generation IVT judder or the GT's 7-speed dry DCT shudder - three different transmissions with three different failure mechanisms.
Common Symptoms
- Hard bang on 6-4 kickdown
- Flare or momentary neutral between upshifts
- Shudder or vibration at light throttle 40-50 mph as lockup applies
- Delayed engagement into Drive or Reverse
- Erratic shift points and slipping under load
How to Fix
Start with a genuine Kia SP-IV fluid exchange (not a high-pressure flush) - degraded fluid accelerates bore wear and sometimes quiets an early shudder. The durable fix is valve-body service: either a remanufactured/OEM valve body, or a bore-repair kit (TransGo SK A6MF and equivalents) that re-sleeves the reducing-valve and TCC control-valve bores. A P0743 almost always means the TCC solenoid itself, which Kia addressed in a transmission TSB. If lockup shudder is severe and long-standing, replace the torque converter with the valve body or the shudder returns. No recall covers this.

The 8-speed automatic exhibits torque-converter (damper clutch) shudder felt as a vibration around 45 mph and during uphill gear changes, plus hesitation and weak pickup on re-acceleration and merges. Early 2020 units could log P0741 damper-clutch faults; some required full transmission/torque-converter replacement.
Common Symptoms
- Shudder/vibration around 45 mph
- Whole-vehicle shudder during uphill gear changes
- Hesitation and weak pickup on re-acceleration
- Harsh or slamming shifts
- Vibration below 1,500 rpm
How to Fix
Kia service action SA428 (TSB 090, early-2020 units built May 18-20, 2020) replaced the entire automatic transmission and torque converter for noise/vibration below 1,500 rpm; later rough-shift/hesitation complaints on MY22 addressed under SA490 (TSB 232) with ECU and TCU software updates. Dealers diagnose via campaign lookup; reflash first, hardware replacement if shudder persists.

Frequently asked questions
What does P0741 mean on a Kia?
P0741 stands for "Torque Converter Clutch Circuit Performance/Stuck Off." This code means the torque converter clutch (TCC) is not working as expected and is effectively stuck off, so the converter clutch isn't locking up the way the computer commands it to. The TCC mechanically links the engine to the transmission at cruising speeds to reduce slippage and improve fuel economy, and the computer compares engine RPM to transmission/output speed to verify lockup. When the expected RPM drop from lockup doesn't happen, it sets this performance code. You may notice higher-than-normal RPM at highway speed, reduced fuel economy, and sometimes elevated transmission temperatures. On Kia it is documented across 9 models: Niro, Sedona, Stinger, Amanti, Forte, Telluride, Sportage, Carnival, Seltos.
What are the most common causes of P0741?
The most common causes of P0741 are: Low, dirty, or degraded transmission fluid, Faulty torque converter clutch (TCC) solenoid, Stuck or worn valve body / TCC control valve, Failed torque converter (internal clutch worn or slipping), Internal transmission leaks reducing apply pressure, Damaged wiring or connector to the TCC solenoid, Faulty transmission control module (TCM/PCM). The specific cause varies by vehicle.
How much does it cost to fix P0741 on a Kia?
Published repair estimates on Kia range from $150 to $5,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
