Clunk when going into first gear?

[huma]

Almost every time I shift into first gear, there's a loud clunk noise. Anyone else have this issue or know why it's doing this?


I have about 250 miles on my BRZ and the grinding/syncro crunch is now gone from second gear. I guess the triple cone syncro's had to be broken in?
I'm about 80 city/20 hwy and I'm getting 28 mpg on my first tank of gas. This is pretty amazing.


Can't wait to fully break in the vehicle and push my brz a little harder.

This is normal according to most people.
This is the same tranny from the lexus IS line .. which is loud.
I personally like it.

you might wanna try search/technical sub forums

It's normal. I think it's even mentioned in the owner's manual.

Same transmission as the IS250? I'm a little disappointed, I thought they would've built a better or modified one for our cars

The auto transmission otoh is amazing. I would've purchased an auto if I didn't love driving manual so much.

I've only heard good things about them, I'll have to dig around to find that post and how much hp/torq they can handle.
I remember it being higher than anything I plan on in the next few years though.

It's based on the Aisin unit from the IS250, but it's been heavily modified. I don't have my source on hand, but I remember reading somewhere that approximately 80% of the parts have been changed out. Someone feel free to correct me if i'm wrong though.

If you want to avoid that noise, you could press on the clutch in neutral for 3-5 secs before putting into 1st gear.

This is more or less accurate. Its based on the same unit but not the same tranny.

Also I think I remember reading somewhere that this tranny unit cannot handle all that much extra torque and hp above stock safely... Someone feel free to correct me if I'm wrong though.
