Parts for your 2002 Toyota Altezza-Transmission filter

2002 Toyota Altezza transmission-filter — what it is and when to service it

Based on Toyota’s factory documentation and Aisin service literature, the 2002 Toyota Altezza automatic does use a transmission-filter. Toyota’s Repair Manual for the SXE10/JCE10 Altezza (Automatic Transmission section) and Aisin’s A650E service manual describe a pan-mounted, serviceable oil strainer (Toyota’s term for the transmission-filter) with magnets under the sump. The Toyota Electronic Parts Catalogue also lists the oil strainer and pan gasket for the A650E/A340E units used in Altezza models of this era. By contrast, the 6‑speed J160 manual gearbox fitted to some Altezzas does not have a transmission-filter, it relies on fluid changes and magnetic drain plugs.

For the automatic Altezza, the transmission-filter’s job is straightforward but vital: it screens out clutch material, fine metal and other grit so the hydraulic circuits and solenoids in the Aisin gearbox keep shifting cleanly. When the filter starts to clog, shifts can feel lazy or flare up, and the fluid can run hotter—none of which is a mate to long transmission life.

Service-wise, this is best treated as part of routine care rather than a “wait till it slips” repair. In Australian and New Zealand conditions—think summer heat, stop–start commutes, and the odd tow—a sensible approach is to replace the transmission-filter and pan gasket and refresh the ATF about every 60,000–100,000 km, or sooner if the fluid is dark or smells burnt. Toyota specifies ATF Type T‑IV (JWS 3309) for these boxes, stick with that spec or a licensed equivalent.

A proper service generally includes:

• Dropping the pan, cleaning or replacing the pan magnets, and fitting a new strainer and pan gasket
• Refilling with the correct ATF in measured litres, then checking level at the correct temperature
• Inspecting for leaks and verifying shift quality on a road test

Handy signs it’s time: delayed engagement when selecting Drive or Reverse, shudder on light throttle, or ATF that’s gone brown. If the car has the J160 manual, skip the transmission-filter altogether, there isn’t one. Just change the manual gearbox oil at sensible intervals and keep an eye on any metallic fuzz on the magnetic plug.

Look after the transmission-filter and fluid, and the Altezza’s Aisin auto tends to reward with crisp shifts and long service life.

Popular questions about 2002 Toyota Altezza transmission-filter

Does a 2002 Altezza have a transmission-filter?
Yes—if it’s an automatic. Toyota’s Altezza repair manual and Aisin’s A650E documentation show a serviceable oil strainer (filter) inside the sump. Manual J160 models don’t use a filter.

How often should the transmission-filter be changed?
As a rule of thumb in AU/NZ conditions, replace the filter and refresh ATF every 60,000–100,000 km, or earlier if the fluid looks or smells off, or the shifts feel lazy.

What fluid should be used after changing the filter?
Use Toyota ATF Type T‑IV (JWS 3309) or an approved equivalent. Mixing types or using the wrong spec can affect shift quality and longevity.
