Buying Automatic Transmission Parts for a 1990 Bentley Continental

On this vehicle, the automatic transmission covers the automatic gearbox and its supporting cast — filters, coolers, solenoids, mounts and torque-converter parts.

  • Confirm you have the 6.7L V8 engine — every part on this page is matched to it.
  • 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.

Start with the largest groups on this page: Extension Housing Seal and Fluid Pan Gasket .

Frequently Asked Questions

How many automatic transmission parts fit the 1990 Bentley Continental?

Our catalog currently lists 61 automatic transmission parts for the 1990 Bentley Continental across 25 subcategories and 16 brands, covering the 6.7L V8 engine. Each part is matched to the engine(s) it fits.

What are the signs of automatic transmission problems on a 1990 Bentley Continental?

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 1990 Bentley Continental 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 1990 Bentley Continental?

Every part on this page is matched to the 6.7L V8 engine. 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.
