Suzuki Transmission Oil Change

I'm changing the transmission fluid on a 2004 Suzuki Forenza. The transmission is an automatic ZF 4HP16 transmission designed for use in a vehicle with front-wheel drive and a transverse engine. The transmission fluid recommended by Suzuki is Esso LT71141.

However, in this video I'm using Valvoline Max Life ATF. Valvoline recommends this product for use in 2004-2008 Forenza; 2005-2008 Reno. Here is the Valvoline link:

Here is the link for the service manual for the NUBIRA/LACETTI (Suzuki marketed a rebadged Lacetti as the Forenza and Reno beginning in the United States in 2004):

Here is another manual:

Here is the Optra manual (another rebadged NUBIRA/LACETTI):

5/16" equals approximately 8 mm (or 7.9375 mm). You would be able to use either size, 8 mm or 5/16", square pipe plug socket to remove the drain plug and fill plug.
