Parts for your 2010 Mitsubishi Lancer-Transmission filter

2010 Mitsubishi Lancer transmission filter — what’s fitted and how to look after it

Based on Mitsubishi factory documentation — notably the Lancer (CY/CZ) Workshop Manual for 2008–2015 (Group 23A: CVT, Group 22C: TC‑SST) and the Mitsubishi ASA electronic parts catalogue for 2010 AU/NZ models — a transmission filter is relevant on certain 2010 Mitsubishi Lancer variants. The 5‑speed/6‑speed manual gearbox does not use a transmission filter. The CVT (Jatco JF011E, Mitsubishi codes F1CJA/F1CJB) uses an internal strainer and, on many AU/NZ cars, a replaceable cooler‑line (external) CVT fluid filter. The TC‑SST dual‑clutch transmission (as fitted to Ralliart/Evolution variants) uses a replaceable hydraulic filter. Jatco service literature for the JF011E and Mitsubishi TC‑SST service procedures both identify these filtration elements, the manual transaxle section shows no filter, only periodic gear oil changes.

Where fitted (CVT and TC‑SST), the transmission filter’s job is straightforward: keep clutch debris, fine metal, and varnish particles out of the valve body, pump, and solenoids so the transmission holds pressure and shifts as it should. In the Lancer’s CVT, filtration protects the pump and the steel belt/pulleys from wear, while in the TC‑SST it keeps the mechatronics happy under heat and high pressure. Clean fluid and a sound filter help the transmission run cooler, last longer, and behave consistently in Aussie and Kiwi conditions.

Servicing wise, the approach differs by unit:

• CVT (F1CJA/F1CJB): The internal strainer is only addressed during overhaul, but the external cooler‑return filter (where fitted) is a service item. Pair its replacement with a CVT fluid change — commonly around 60,000 km in local conditions, sooner if the vehicle tows, sits in traffic, or sees hot climates. Always use the specified Mitsubishi CVT fluid (DiaQueen CVTF to the correct spec) and follow the fill/temperature calibration procedure.
• TC‑SST: The hydraulic filter is replaceable and should be renewed with the SST fluid at intervals noted in the workshop schedule (often 30,000–60,000 km, model and usage dependent). The TC‑SST uses dedicated fluids for the clutch/hydraulic circuit and for the gearset, both need to be correct grade and quantity.

Handy pointers:

• Confirm by VIN which transmission is fitted, service parts differ between CVT and TC‑SST, and manual gearboxes do not have a filter.
• Watch for symptoms of restriction: rising transmission temps, flare or slip on a CVT, harsh or delayed shifts on a TC‑SST. Address promptly to avoid collateral wear.
• Use OEM‑quality filters and seals, replace crush washers, and torque fasteners to spec. A clean fill and proper fluid temperature setup make a big difference.

Why the manual Lancer has no filter: manual gearboxes are splash‑lubricated with gear oil and don’t have the same fine hydraulic control circuits as autos/CVTs, particulate trapping is handled by drain‑and‑refill rather than an in‑line filter.

Popular questions

Does a 2010 Mitsubishi Lancer have a transmission filter?
It depends on the transmission. Manual Lancers don’t use a filter. CVT models have an internal strainer and, on many AU/NZ cars, a serviceable external cooler‑line filter. TC‑SST dual‑clutch models have a replaceable hydraulic filter. Mitsubishi’s workshop manual and ASA parts listings confirm these setups.

How often should the transmission filter be replaced?
For CVT cars with an external filter, replace it with the CVT fluid service — commonly about 60,000 km in local conditions, sooner for heavy use. The internal CVT strainer is typically only replaced during overhaul. For TC‑SST, replace the hydraulic filter with the SST fluid at roughly 30,000–60,000 km depending on usage and the specific service schedule. Always verify intervals for the exact variant.

What are signs the filter may be clogged or due?
On CVT models: rising transmission temperature warnings, droning/whine, flare, or hesitant take‑off. On TC‑SST: harsh or delayed shifts, limp mode, or overheating messages. These symptoms can have multiple causes, but a restricted filter and old fluid are common contributors and should be checked first.
