Known Toyota Mark X faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01U760E Torque Converter Shudder at Light Throttle
MajorCommonTransmission $300–$5,500 to fix
The GRX130 Mark X pairs its 4GR-FSE or 2GR-FSE engine with Toyota's 6-speed U760E automatic transmission. The torque converter lock-up clutch engages at cruising speeds to eliminate slip and improve fuel economy. When ATF degrades or becomes contaminated, the clutch friction material glazes and the clutch chatters as it applies, producing a rhythmic shudder felt through the drivetrain and body at light throttle, typically between 40 and 80 km/h. Many Japanese-imported examples arrive with ATF that has never been serviced beyond the JDM 'lifetime fill' recommendation, which significantly understates real-world fluid life. Early intervention with a drain-and-fill using genuine Toyota ATF Type WS resolves many cases. Shudder that persists after two ATF changes indicates friction material wear inside the torque converter itself, requiring a full converter replacement or transmission rebuild.
Symptoms to notice
Rhythmic shudder or vibration at light throttle between 40-80 km/h
Vibration that disappears under firm acceleration or when fully off throttle
Shudder worsens when transmission is warm
Slight hesitation or pulsing sensation felt through the seat and floor
May trigger torque converter or transmission slip codes in some cases
What to check
Test drive at steady light throttle between 60 and 80 km/h on a flat road. Any rhythmic vibration that stops when you accelerate firmly or lift off is torque converter shudder. Check ATF colour and smell — should be red and odourless. Request ATF service records.
Where to look: U760E 6-speed automatic transmission and torque converter, front of transmission bell housing
Ask the seller
“When was the ATF last changed and what fluid was used?”
“Have you noticed any vibration or shudder at highway speeds under light throttle?”
“Has the transmission ever been serviced or had any work done?”
“Are there any transmission-related warning lights or codes?”
02Electric Power Steering Rack Rattle and Clunk
MinorOccasionalSuspension $500–$2,200 to fix
The GRX130 Mark X (2009–2019) is equipped with a column-mounted electric power steering (EPS) system. The steering rack uses an internal ball-nut mechanism driven by the electric motor. As the rack ages, the internal pre-load on the ball-nut mechanism decreases due to wear and bush deterioration, causing a clunk or rattle when the steering wheel is moved at low speeds, particularly on rough surfaces or during parking manoeuvres. The EPS column reduction gear can also develop lash.
Symptoms to notice
Clunking or rattling noise from the steering rack area when driving slowly over speed humps or rough surfaces
Knocking felt through the steering wheel when the car hits a bump with the wheel turned
Occasional steering pull or self-centering resistance inconsistency pointing to internal rack wear
Noise is absent on smooth roads at motorway speeds but returns on rough suburban surfaces
What to check
With the vehicle stationary on a rough surface or during a slow-speed turn, listen and feel for clunks through the steering wheel. Have an assistant turn the steering wheel lock-to-lock while a second person feels the rack body for movement or listens at the rack housing for internal knocking. Check all steering rack mounting bush condition by inspecting for cracking or compression set. Verify EPS column coupler and intermediate shaft joints are tight.
Where to look: Steering rack mounted behind the front subframe; EPS motor and reduction gear on the steering column below the dashboard
Ask the seller
“Does the steering wheel transmit any clunking or knocking when driving over rough roads or speed bumps?”
“Has any steering noise or handling complaint been reported or repaired?”
