Parts for your 2007 Toyota Mark x-Cluth slave cylinder

2007 Toyota Mark X cluth-slave-cylinder — is it actually a thing?

Short answer: a cluth-slave-cylinder (clutch slave cylinder) isn’t used on the 2007 Toyota Mark X. That model (GRX12# series) was sold with automatic gearboxes only, so there’s no clutch pedal, no hydraulic clutch circuit and no slave cylinder to operate one.

Why it’s not there: the 2007 Mark X runs an Aisin electronically controlled automatic (commonly A650E for the 3.0 V6 and A960E/A960E-family for the 2.5 V6). These transmissions use a torque converter and an internal valve body to manage gear shifts. Because there’s no manual clutch to disengage, there’s no need for a cluth-slave-cylinder on this vehicle.

If a parts listing shows a 2007-toyota-mark-x cluth-slave-cylinder, it’s usually a catalogue mix-up with other Toyota rear-drive sedans that did have manual options, or with later special editions (like much newer GRMN variants) that ran a proper 6-speed manual. For a standard 2007 Mark X, the part simply doesn’t apply.

What owners should look after instead: treat the automatic transmission to the right fluid and service intervals. Toyota WS (World Standard) ATF is the specified fluid for these Aisin boxes. Good practice is to check for leaks at the transmission pan and cooler lines, keep an eye on shift quality, and have the fluid condition inspected around the 80,000–100,000 km mark (or sooner under hard use). If the vehicle has been manual-converted (rare but possible), a cluth-slave-cylinder would then be part of the bespoke setup and should be matched to the specific gearbox and bellhousing used in the conversion.

Technical sources that document no cluth-slave-cylinder for 2007 Mark X:

• Toyota Mark X GRX120/121/125 Repair Manual and New Car Features (Toyota TIS) – specifications list automatic transmissions only for MY2007.
• Toyota Electronic Parts Catalogue (EPC) for GRX12# – no clutch master/slave or release components shown for 2007 models.
• 2007 Toyota Mark X sales specification sheets – indicate 5-speed and 6-speed automatic transmissions, with no manual option.

FAQs

Does a 2007 Toyota Mark X have a cluth-slave-cylinder?
No. The 2007 Mark X is automatic-only, so there’s no hydraulic clutch system and no slave cylinder fitted from factory.

Why do some sites list a 2007-toyota-mark-x cluth-slave-cylinder?
Parts catalogues sometimes overlap models and years. The Mark X nameplate spans variants and generations, some later or special models (and unrelated Toyota sedans) offered manuals. That’s why a cluth-slave-cylinder can appear against the 2007 car even though it doesn’t use one.

What drivetrain servicing should an owner consider instead?
Focus on automatic transmission care: correct Toyota WS ATF, pan gasket/filter service as required, and checks for shift quality and leaks. Also keep driveline items like the prop shaft centre bearing and differential oil in good nick.
