Buying Automatic Transmission Parts for a 1982 Avanti Ii

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 5.0L 305cid 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: Fluid Pan Gasket and Shift Improvement Kit .

Frequently Asked Questions

How many automatic transmission parts fit the 1982 Avanti Ii?

Our catalog currently lists 125 automatic transmission parts for the 1982 Avanti Ii across 31 subcategories and 21 brands, covering the 5.0L 305cid V8 engine. Each part is matched to the engine(s) it fits.

What are the signs of automatic transmission problems on a 1982 Avanti Ii?

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 1982 Avanti Ii 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 1982 Avanti Ii?

Every part on this page is matched to the 5.0L 305cid 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.
