6-Speed Automatic (6AT)
Used on relevant older Santa Fe automatics and current hybrid/PHEV powertrains. Valve-body control, clutch application and hybrid integration are important diagnostic areas.

Hyundai Santa Fe Gearbox Repair Specialists in the Midlands
Specialist diagnosis and repair for Hyundai Santa Fe automatic gearboxes, including earlier conventional automatics, the eight-speed automatic used on the fourth-generation diesel before its facelift, the later eight-speed wet DCT diesel and the six-speed automatic used on Hybrid and Plug-in Hybrid models.
If your Santa Fe shudders at cruising speed, delays before Drive, slips under load, bangs between gears or shows a transmission warning, we identify the automatic or DCT generation before repair.

Which Santa Fe Do You Have?
Hyundai Santa Fe Types, Generations and Gearboxes
Santa Fe models have used several conventional automatic transmissions over the years. Fourth-generation diesel models launched with an 8-speed automatic, later facelift diesels moved to an 8-speed wet DCT, while hybrid and plug-in hybrid models use a 6-speed automatic.
| Santa Fe generation / type | Typical UK versions | Automatic gearbox | What owners often search for |
|---|---|---|---|
| Santa Fe CM, 2006–2012 | 2.2 CRDi and petrol automatic versions | Conventional automatic, including 5/6-speed applications depending on year | Santa Fe automatic fault, converter shudder, delayed Drive |
| Santa Fe DM, 2012–2018 | 2.2 CRDi automatic | 6-speed conventional automatic on relevant UK cars | Santa Fe 6AT fault, valve body, harsh shift |
| Santa Fe TM, 2018–2020 | 2.2 CRDi | 8-speed conventional automatic | Santa Fe 8-speed automatic shudder, gearbox warning |
| Santa Fe TM facelift, 2020–2024 | 2.2 CRDi, Hybrid, Plug-in Hybrid | Diesel 8-speed wet DCT; Hybrid/PHEV 6AT | Santa Fe 8DCT fault, Hybrid 6AT warning, clutch shudder |
| Santa Fe MX5, 2024–present UK | Hybrid and Plug-in Hybrid | 6-speed automatic | New Santa Fe gearbox fault, Hybrid transmission warning |
Not sure which gearbox is fitted? A 2019 diesel Santa Fe and a 2021 diesel Santa Fe can use fundamentally different eight-speed transmissions. Hybrid/PHEV models use 6AT. We confirm build data first.

Hyundai Santa Fe Gearbox Models Explained
8-Speed Conventional Automatic
The fourth-generation diesel launched with an eight-speed torque-converter automatic. Converter lock-up, valve-body control and internal clutch wear are key repair areas.
8-Speed Wet DCT
The later 2.2 Smartstream diesel moved to an oil-cooled eight-speed dual-clutch transmission. Hydraulic control and wet clutch condition require a different diagnostic route from the earlier 8AT.
Common Problems
Common Hyundai Santa Fe Gearbox Issues
Santa Fe faults are especially easy to misdiagnose because two different eight-speed transmission types were used around the fourth-generation facelift, while hybrid models use 6AT.
Judder or Shudder
Vibration during pull-away or a gear change can involve clutch engagement, converter lock-up, adaptation or hydraulic control depending on the transmission fitted.
Delayed Drive or Reverse
A pause after selecting gear can point towards clutch application, actuator operation, hydraulic pressure, valve-body/mechatronic control or internal wear.
Harsh or Jerky Changes
Abrupt shifts can involve solenoids, adaptations, clutch wear, pressure regulation or internal mechanical damage.
Transmission Warning / Limp Mode
A warning or restricted gear operation should be scanned with Hyundai-compatible diagnostics before parts are replaced.
Slipping / RPM Flare
If engine speed rises without matching acceleration, clutch slip or hydraulic pressure loss should be investigated quickly.
Whine / Clunk / Vibration
Noise can come from the transmission, but mounts, driveshafts, wheel bearings and AWD components can sometimes feel gearbox-related.
Describe the Symptom
What Does a Hyundai Santa Fe Gearbox Fault Sound or Feel Like?
Tell us whether the Santa Fe shudders at steady motorway speed, judders from a standstill or changes harshly during hybrid operation; the pattern helps identify converter, DCT clutch or hydraulic faults.
| 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: HTRAC/AWD, propshaft, differential and wheel/tyre issues can create vibration or binding that feels gearbox-related. The drivetrain should be checked where the complaint is load- or turn-related.
Diagnostic Trouble Codes
Hyundai Santa Fe Gearbox Fault Codes
Santa Fe fault codes must be interpreted by gearbox generation. A converter code on an 8AT is not the same diagnostic path as a wet-DCT clutch or pressure fault.
| 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 |
Transmission identification is particularly important on 2018–2024 Santa Fe models because both conventional 8-speed automatic and 8-speed wet DCT systems exist.
Repair Costs
How Much Does a Hyundai Santa Fe Gearbox Repair Cost?
Santa Fe repair costs vary between 6AT, conventional 8AT and the higher-capacity wet 8DCT used on later diesel models.
| 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 identify the Santa Fe generation, engine, Hybrid/PHEV status, HTRAC configuration and exact transmission.
Scan the transmission
Hyundai-compatible diagnostics are used to read gearbox, converter/clutch, hydraulic and hybrid-control data.
Test the fault area
6AT/8AT valve-body and converter operation or 8DCT clutch/hydraulic behaviour is tested alongside the AWD driveline.
Quote the correct repair
We recommend the repair indicated by the diagnosis and confirm the price before work begins.

Common Questions
Hyundai Santa Fe Gearbox Problems: Straight Answers
What automatic gearbox does a Hyundai Santa Fe use?
It depends on generation. Santa Fe models have used 6-speed conventional automatics, an 8-speed conventional automatic, an 8-speed wet DCT on later diesel versions, and 6AT on Hybrid/PHEV models.
Did the Santa Fe diesel use both an 8-speed automatic and 8-speed DCT?
Yes. The fourth-generation diesel initially used an 8-speed conventional automatic, while the facelift 2.2 Smartstream diesel moved to an 8-speed wet DCT.
What gearbox does the Santa Fe Hybrid use?
Hyundai's hybrid Santa Fe uses a six-speed automatic transmission.
Why does my Santa Fe shudder at motorway speed?
Torque-converter lock-up is one possible cause on conventional automatics, but tyres, propshafts and AWD components can produce similar vibration.
How much does a Santa Fe gearbox repair cost?
Costs vary significantly between 6AT, 8AT and wet 8DCT systems. A fixed quotation should follow gearbox identification and diagnosis.
Can HTRAC cause a gearbox-like fault?
Yes. AWD and driveline components can cause binding, vibration and clunks that feel transmission-related.
