'06 Manual Transmission Fluid Change - Interval, Spec, and No Drain Plug?

[Nickelbawker]

Just changed mine




Wasn't sure if I had the same filler bolt as OP so here's some pictures.

Feels better, first gear is way easier. I think I was way under by at least half a quart($500 Aveo life). Shifts feel smoother like the Royal Purple claims.

There's a PDF floating around that says what fluid they use and it says Syncromesh fluid for certain years of the same transmission that has the weight listed but it also says Syncromesh after that. I went with Royal Purple($16ea at orielly's) because it felt thicker like it would offer more protection than the Syncromesh Valvoline that was only about $10ea.

I left my gasket up there on the trans as well and de greased both then cross pattern torqued it back down lightly.
