Buying Automatic Transmission Parts for a 2021 Alfa Romeo Giulia
On this vehicle, the automatic transmission covers the automatic gearbox and its supporting cast — filters, coolers, solenoids, mounts and torque-converter parts.
- Match the engine first. Some automatic transmission parts fit every engine; others are engine-specific. Each row shows which engine(s) it fits.
- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace the filter and pan gasket with every fluid service, and flush the cooler lines when replacing a failed unit.
- Cross-reference the manufacturer part number against your old part or a service-manual listing.

Frequently Asked Questions
How many automatic transmission parts fit the 2021 Alfa Romeo Giulia?
Our catalog currently lists 55 automatic transmission parts for the 2021 Alfa Romeo Giulia across 15 subcategories and 12 brands, covering both the 2.0L L4 Turbocharged and the 2.9L V6 Turbocharged. Each part is matched to the engine(s) it fits.
Do automatic transmission parts differ between 2021 Alfa Romeo Giulia engines?
Some do. 24 parts fit every engine; the other 31 are engine-specific. Each row (and the filter at the top) shows which. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of automatic transmission problems on a 2021 Alfa Romeo Giulia?
Common symptoms include delayed or harsh engagement, slipping under load, fluid that smells burnt, or shuddering at light throttle around 40 mph. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, replace the filter and pan gasket with every fluid service, and flush the cooler lines when replacing a failed unit.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2021 Alfa Romeo Giulia was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2021 Alfa Romeo Giulia?
First match the engine — each row shows which engine(s) the part fits. Then use exactly the fluid specification in the notes — automatic transmissions are the least forgiving component on the vehicle about fluid choice. The notes column carries position and trim qualifiers where they apply.
