6-Speed Automatic (6AT)
Six-speed automatic Santa Fe models use traditional hydraulic control and torque-converter operation, making valve-body wear, solenoids and converter condition key diagnostic areas.

The Hyundai Santa Fe has progressed through conventional five-/six-speed automatics, an eight-speed automatic, an eight-speed wet DCT on selected diesel models and current Hybrid/PHEV six-speed automatic systems.
Because the Santa Fe is a heavier SUV, converter shudder, hydraulic pressure loss and clutch slip can become more noticeable under load, while AWD components can create vibration that feels transmission-related.

Hyundai Santa Fe Gearbox Models Explained
8-Speed Conventional Automatic
The eight-speed conventional automatic used on relevant TM-generation diesels extends the same broad hydraulic principles but adds more ratios and control complexity.
8-Speed Wet DCT
The eight-speed wet DCT fitted to selected later diesels uses oil-cooled clutches and different hydraulic control, while Hybrid/PHEV models use a six-speed automatic integrated with the electrified powertrain.
Common Problems
Common Hyundai Santa Fe Gearbox Issues
Santa Fe search intent often centres on '8-speed gearbox shudder', '8DCT fault', 'delayed Drive', 'harsh shifts', 'Hybrid transmission warning' and 'converter vibration'. Those phrases only become useful once the exact transmission is established.
Judder or Shudder
Steady-speed shudder can involve torque-converter lock-up on conventional automatics or AWD/driveline vibration outside the gearbox.
Delayed Drive or Reverse
Delayed Drive or Reverse may result from pressure leakage, valve-body wear, converter fill or internal clutch application.
Harsh or Jerky Changes
Harsh shifts can be caused by solenoid control, hydraulic pressure, adaptation or internal wear on six- and eight-speed automatics.
Transmission Warning / Limp Mode
An 8DCT fault can involve wet-clutch condition, hydraulic control, temperature or actuator/mechatronic behaviour and needs DCT-specific testing.
Slipping / RPM Flare
Hybrid/PHEV transmission warnings should be checked across the six-speed automatic and electrified powertrain rather than as an isolated gearbox fault.
Whine / Clunk / Vibration
Clunks or vibration under load can also arise from propshaft, differential, driveshaft and AWD components.

Describe the Symptom
What Does a Hyundai Santa Fe Gearbox Fault Sound or Feel Like?
Tell us whether the Santa Fe symptom appears under acceleration, during towing, at steady road speed, when selecting Drive or during hybrid operation. Load and drivetrain mode are valuable clues on this model.
| What you notice | How drivers describe it | Possible areas to investigate |
|---|---|---|
| Judder pulling away | “It shakes as I move off or reverse.” | Clutch/actuator, adaptation, mechatronic control, flywheel or mounts |
| Delay then thump | “I select Drive and it pauses before engaging.” | Hydraulic pressure, clutch application, actuator or valve-body/mechatronic operation |
| RPM flare | “The revs rise before the next gear takes.” | Clutch slip, pressure loss, converter lock-up or internal wear |
| Harsh downshift | “It bangs as I slow down.” | Adaptation, solenoid/clutch control, mounts or internal wear |
| Whine or hum | “The noise changes with road speed.” | Transmission bearings, differential, driveshaft or wheel bearing |
| Warning / limited gears | “The transmission warning appears and it stops shifting normally.” | Stored TCM DTC, pressure/control fault, clutch data or protection mode |
Important: Steady-speed vibration can come from torque-converter lock-up or the wider AWD driveline.
Diagnostic Trouble Codes
Hyundai Santa Fe Gearbox Fault Codes
Santa Fe codes are interpreted against 6AT, 8AT, 8DCT or Hybrid/PHEV architecture. Converter slip, clutch temperature, pressure and AWD/hybrid data are checked according to the actual transmission.
| Fault code | What it broadly relates to | What may need checking |
|---|---|---|
| P0700 | Transmission control system warning request | Read the transmission control module for the underlying gearbox-specific DTCs |
| P0715 | Input / turbine speed sensor circuit | Speed-sensor signal, wiring, control data and internal transmission operation |
| P0722 | Output speed sensor signal fault | Output-speed signal, wiring, sensor data and transmission control |
| P0730 | Incorrect gear ratio | Commanded versus actual ratio, clutch application, hydraulic pressure and internal wear |
| P0741 | Torque-converter clutch performance on applicable conventional automatics | Converter lock-up, valve body, pressure control and fluid condition |
Diesel 8DCT and Hybrid/PHEV six-speed automatic Santa Fe models use fundamentally different clutch and hydraulic systems.
Repair Costs
How Much Does a Hyundai Santa Fe Gearbox Repair Cost?
Santa Fe repair pricing varies from valve-body and torque-converter work to wet 8DCT clutch/hydraulic repairs and full transmission reconditioning.
| Hyundai Santa Fe gearbox work | Typical guide range | What can change the price? |
|---|---|---|
| Diagnostic scan and road test | From £30 | 6AT, 8AT, 8DCT and AWD/hybrid complexity |
| Valve-body / solenoid related repair | Approx. £800 - £1,700 | Automatic gearbox family and hydraulic wear |
| Torque-converter related repair | Approx. £900 - £1,800 | Where fitted; converter condition and labour |
| 8DCT clutch / hydraulic related repair | Approx. £1,200 - £2,200+ | Wet clutch and control-system condition |
| Full Santa Fe gearbox reconditioning | Approx. £2.5k - £4.5k+ | Transmission family, AWD and internal damage |

How We Diagnose a Hyundai Santa Fe Gearbox Fault
Identify the gearbox
We confirm Santa Fe generation, engine, AWD and Hybrid/PHEV specification.
Scan the transmission
Hyundai-compatible diagnostics are used to inspect pressure, converter, clutch, temperature and relevant hybrid/AWD data.
Test the fault area
The fault is reproduced under the road speed or load condition where the owner experiences it.
Quote the correct repair
We then quote the hydraulic, converter, DCT or internal repair indicated by the diagnosis.

Common Search Questions
Hyundai Santa Fe Gearbox Problems: Straight Answers
Why is my Hyundai Santa Fe shuddering at motorway speed?
On conventional automatic versions, torque-converter lock-up is one area to investigate, but propshaft, differential, wheel and AWD vibration can feel very similar.
Did the Hyundai Santa Fe use both an 8-speed automatic and an 8-speed DCT?
Yes. Relevant TM-generation models used an eight-speed conventional automatic, while selected later diesel versions used an eight-speed wet dual-clutch transmission.
What causes delayed Drive on a Hyundai Santa Fe?
Hydraulic pressure loss, valve-body wear, torque-converter fill and internal clutch application can all cause a pause before engagement on conventional automatics.
What gearbox does the Hyundai Santa Fe Hybrid use?
Current UK Hybrid and Plug-in Hybrid Santa Fe models use a six-speed automatic transmission integrated with the electrified powertrain.
How much does a Hyundai Santa Fe gearbox repair cost?
The guide table lists valve-body work around £800–£1,700, converter repair around £900–£1,800 and full reconditioning around £2.5k–£4.5k.
Can AWD faults mimic a Santa Fe gearbox problem?
Yes. Propshaft, differential, driveshaft and AWD faults can create clunks or vibration that should be ruled out before internal gearbox repair.
