Parts for your 2005 Toyota Altezza-Transmission filter

2005 Toyota Altezza transmission filter — what it does and when to service it

Based on Toyota’s factory Repair Manual for the SXE10/JCE10 Altezza (A/T section), the Toyota Electronic Parts Catalogue, and Aisin service literature for the A340E and A650E, the 2005 Altezza’s automatic transmissions use an internal automatic transmission fluid (ATF) oil strainer—commonly called a transmission filter—mounted to the valve body under the sump pan. So yes, a transmission filter is relevant on auto Altezzas. Manual models (J160 6‑speed) don’t run a conventional filter, they use gear oil only.

The filter’s job is simple but crucial: it screens out clutch material, fine metal and other debris so the valve body and solenoids get clean fluid. Magnets in the pan catch ferrous particles, the filter captures the rest. Keeping that flow clean helps the box shift smoothly and last longer, especially in stop–start city driving or when the car’s been driven hard.

Toyota documents typically call it an “oil strainer” and note replacement when contaminated or damaged rather than at a fixed interval. In real-world Aussie and Kiwi conditions, it’s smart to replace the filter whenever the pan is off, or roughly every 100,000–150,000 km, and always if there are shift issues or burnt, dirty ATF. Fluid choice matters: Toyota Genuine ATF Type T‑IV (JWS 3309) is the correct spec for the period A340E/A650E units.

A good service plan for an automatic Altezza looks like this:

• Every 60,000–80,000 km (or sooner for heavy use): drain and refill ATF, clean the pan and magnets, inspect debris.
• At 100,000–150,000 km or if contamination is found: replace the filter/strainer and pan gasket, refill with Type T‑IV, and set level using Toyota’s temperature procedure.

Watch for tell-tales like delayed engagement, flare on upshifts, harsh shifts, or a shudder, these often go hand-in-hand with dirty ATF and a loaded filter. When servicing, many techs prefer a pan service over a high-pressure “flush” on older boxes—gentler, with less risk of stirring up settled debris.

For manual Altezza owners, there’s no transmission filter to replace. Just renew the correct-grade manual trans oil at sensible intervals, check for leaks, and you’re laughing.

FAQs

Does a 2005 Altezza have a transmission filter?
Yes—automatic models with Aisin A340E or A650E use an internal oil strainer under the pan, as shown in Toyota’s Altezza repair manual and the Toyota EPC. Manual J160 models don’t have a serviceable filter.

How often should the Altezza transmission filter be replaced?
Toyota treats it as a strainer to replace when contaminated or during overhaul. In local conditions, many workshops replace it at 100,000–150,000 km or whenever the pan is off, with ATF changes every 60,000–80,000 km.

What ATF does it take and how much will I need?
Use Toyota ATF Type T‑IV (JWS 3309). A typical pan drain/refill takes roughly 2–3.5 litres, a full dry fill is higher and varies by transmission. Set the level using Toyota’s temperature-based procedure for accuracy.
