Do I need a special tool to fill this transmission?

Yes — the 09P/AQ450 uses a fill-level port rather than a dipstick. A suitable fluid pump and overflow pipe tool are recommended for correct fill level.

Is the ATF in this kit VAG-approved?

Yes. The VAICO fluid meets the VW TL 521 82 specification required for the AQ450 / 09P gearbox.

How long does this service take?

Typically 1–2 hours for a trained technician including warm-up and fill-level check procedures.

Can I reuse the sump gasket?

No — the gasket should always be replaced during a service. This kit includes a new gasket for a clean, leak-free seal.

Will this kit work on the AQ450 in the VW Atlas (North American market)?

The core 09P transmission is shared, but verify your specific build date and variant before ordering.

Delivery and Shipping

UK delivery — parts we hold in stock

Ordered before 2pm on a working day, these are dispatched the same day by express courier and normally arrive within 1–2 working days.

Parts supplied from our European supplier

A large part of our range is held by our supplier in Germany rather than on our own shelves. We order these in for you as soon as you place the order. They normally dispatch within 7–10 working days, and are then sent on by express courier like anything else. Nothing ships to you direct from Germany — it comes to our Arlesey workshop first, so you deal only with us for returns and warranty.

Collection from Arlesey

Click and collect is available on parts we physically hold. If an item has to come in from our supplier it cannot be collected, and checkout will tell you so before you pay.

International

3–5 working days once dispatched. Any customs charges or excise duties are the responsibility of the buyer.

VAICO AQ450 / 09P Automatic Transmission Oil Service Kit — Audi & VW

Regular fluid servicing is essential on the 09P (AQ450) 8-speed automatic transmission used in quattro and 4MOTION Audi and Volkswagen vehicles. Over time the ATF degrades and the filter becomes restricted, which can cause harsh or delayed gear changes and accelerated internal wear. This VAICO EXPERT KITS+ service kit contains everything required for a complete standard oil change in one box — no sourcing individual components separately.

What's Included

Replacement transmission oil filter element
Oil sump gasket
3 litres of VAICO automatic transmission fluid (ATF)
Drain/fill plugs and complete bolt & screw set

OE references: 09P 325 429, 09P 321 370
