Q 1. What is BG 303E-PK2 transmission fluid for?

A. The 303E-PK2 is a fluid conditioner — an additive added to fresh transmission fluid in CVT, DCT and DSG gearboxes, both belt-type and chain-type. It enhances oxidation stability, prevents deposit formation, prolongs fluid life and improves anti-wear properties. Not for use in standard step-shift automatic transmissions.

Q 2. Which vehicles take 303E-PK2 fluid?

A. The 303E-PK2 is added to the transmission fluid in vehicles with CVT (belt-type or chain-type), wet dual-clutch transmissions, or direct-shift gearboxes. Compatible with most CVT and DCT fluids in passenger cars. If unsure about your specific vehicle, contact PartsForMachines before fitting.

Q 3. What is the 303E-PK2 container size?

A. Each 303E bottle is 177ml — the 303E-PK2 contains two bottles. This is a conditioner additive, not the full transmission fluid; follow the dosage guidance on the product label for the volume to add to fresh fluid at service.

Q 4. Does using 303E-PK2 affect the gearbox warranty?

A. The 303E-PK2 is a fluid conditioner used alongside the manufacturer's specified transmission fluid — it does not replace the OEM fluid. Where a manufacturer mandates a specific branded fluid or no additives, the workshop should confirm before use.

Q 5. What does ordering the 303E-PK2 include?

A. 303E-PK2 bundles 2 of the 303E together. Same product, cheaper per unit. The single 303E sits on its own listing for one-off orders.

Q 6. What if the part doesn't fit or arrives damaged?

A. Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the UK. For items damaged on arrival, report within 24 hours with photos to [email protected] — we will arrange collection and replacement at no cost. The Fit Guarantee covers hassle-free returns for parts that don't fit. Refunds go to the original payment method once inspected.

Q 7. How quickly will I get my order and where do you deliver?

A. Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and 'Check where we deliver' confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa. Use the country selector at checkout to confirm coverage and delivery options for your destination.
