I changed my trany fluid on my 05 WRX 5 speed. I only have 8k on it. Seen a few pictures of metal flakes and chunks on the oil plug magnet, on this sight. Some people said it was normal. Was from assembly in the factory. Well I wanted to see if mine had any. Did not want any in my trans, even if stuck to magnet. Well happy to say I only had a normal amount of fuzz after a break in. Anyhow, I put in 3.7 quarts of Valvoline 75W90, per manual. Trans seemed to shift smother, thought that was just in my head. But when you down shift, that gear wine you hear was GREATLY reduced! But when I check the fluid the dipstick shows a little over full. Opinions?
