The 2006 Nissan Altima Transmission Fluid Type and Capacity

Published on February 11th, 2023 by

The 2006 Altima is available in either a 4 or 6-cylinder but the automatic transmission fluid type doesn’t change. The total fill capacity for the transmission is different though and we will state the correct capacity later in this article.

What kind of ATF (Automatic Transmission Fluid) does my Altima use?

Nissan Matic, DexronTM III/MerconTM, or similar according to the manual. We have a similar fluid that meets or exceeds these requirements mentioned later below.

How many quarts of fluid do I need? Does it depend on engine size?

Yes, it depends on the engine size. The 2.5L or 4-cylinder needs 9.7 quarts and the 3.5L/6-cylinder takes 7.7 quarts. These amounts are total fill, or the total amount the entire transmission will hold.

Where can I read the owner’s manual in case I cannot find it inside my vehicle?

Here is a link for it!
