shifter issue?

yea it feels like it's right as it goes in. doesn't matter how long i hold the clutch in.

What might help is to get your car up in the air and have someone row through the gears. That's how I was able to find that the bearing in the shifter linkage was the issue. Worked out for me as I was having the short shifter put in while doing it so it was just part of the procedure, but it helped a lot, mentally, finally knowing what the cause of the problem was.

all the problems everyone has described in this thread, i've experienced -- I've always thought it was just normal. I often second guess myself if i've pressed the clutch pedal all the way down, but now I know it's not just me.

hopefully this will get remedied soon.

If you and the others' description is correct, I highly doubt it has anything to do with your clutch. It would seem that it's either in the tranny itself or an issue somewhere down the linkage chain.

IRRC, cable linkage types can have these types of issue more so than rod linkage types. That's why I say get the car in the air to visually check to see the linkage at work. Might be a very simple kink in the cable or some sort of obstruction.

Definitely appreciate the feedback -- I'll try to get to that when i'm able to. Since I'm still learning about the mechanics of cars in general i'm not even quite sure what to look for.

I'll research and see if this can be quickly resolved.

Yeah, I'd hate to drive a car with a bad tranny action and feel. A bad transmission action and feel is what prompted me to sell my 2005 G35 coupe after only a year of ownership. IMO, the transmission is something you interface with every second you drive your car and if that doesn't feel right then you just won't have a good driving experience. If you DD and do a lot of bumper to bumper driving then it only goes to exagerate the issue even more.

So I feel you guys on the issues you're facing. Hopefully, you'll get this resolved in a hurry and get back to enjoying the car. :happy0180:

Most RWD vehicles don't have a cable linkage, that's a necessity for FWD cars. Below are pics and sketches of our tranny.

In regards to the OP, I agree that the transmission is a bit inconsistent, sometimes rough, sometimes butter, 1st-3rd are definitely rougher. I played with a buddies WRX and it was surprisingly similar (although our transmission is definitely mostly Toyota). It's an unrefined sports car, as long as stuff isn't making awful gear destroying noises it's probably fine. Maybe see if you can get a test drive in another one to compare.

i may try greasing up that joint where the shifter handle connects up front. I've seen similar posts in other forums for various cars and people said they greased it up better and it made a big difference. I figure it might be worth trying.

Anyone have a short shifter that can comment on whether or not it made a difference with this problem? I know the kartboy specifically has a better bearing at that bottom joint and i'm curious if something like that helps this particular annoyance

If the thunk still occurs after completely depressing the clutch for 3 seconds or more, then the transmission isn't being completely decoupled from the engine, either the clutch isn't fully disengaging or the pilot bearing has too much friction. If you have this symptom and inconsistent notchy shifting, the two may have a related cause.

hmm good call. i'll try to pay attention to it on my way to work in the morning and see how many times it has the thunk. It's a painful stop and go commute so i'll have plenty of chances to see. I wonder if it's got an air bubble in the line or something? I have noticed that once it gets a real rough shift it seems to stay that way for a while and then eventually gets a bit better as if something's settling out

Originally I test drove a manual trans and felt it was exactly like you described, notchey metal rubbing against Rocks feeling. i hated it and thought something was wrong with the shifter, not even addressing the clutch pedal engagement point. so, when I placed my order I suffered with the thought of ordering the automatic version but didn't want the manual I just test drove. I ended up ordering the auto version (because all of the auto mag journalist positive reviews) and have really enjoyed the transmission. I think the manual mode/sport button/ paddle shifters are great.

But....I tested a fellow BRZ owners manual transmission, who had switched out his shifter internals and he also adjusted the clutch pedal catch point and it was extremely smooth, fluid and tight and also great clutch feel. I wish I knew then what I know now, I'd have ordered the manual trans and replaced the shifter parts and adjusted the pedal, for the incredible feel of engagement.

Still love my manumatic though. No regrets, just like both transmission versions now.

Yeah, I'm looking for his profile now and will post link when found

Update: Okay maybe someone can help me, I know the person I'm referencing is named Leon(sic). He owns a GBS BRZ, w/ a front black grill/screen mod. He owns three cars and at one time posted them for sale on the car classified section (BRZ, WRX, and a Acura ?) anyhow, I thought his forum name was Dark Sunrise or Sunshine but I think I might be mistaken. Anyhow, please buzz in if you know his screen name. I'm exhausted w/ searching all the sub categories. Thx
