Ok I have a 1990 S13 fastback with about 152xxx miles on it. My shifter shakes at around 2-3rd gear, but cant figure out whats wrong, maybe its loose? Also my rear end shakes a lot. I'm thinkin I just need my tires balance kuz it only shakes at around 25mph to 45. But after 45 the shaking is goes away. Oh btw I never shift pass 3.5k unless messin around and stuff.Thanks

Go on a diet.

Seriously, fix a flat will cause your tires to shake like a small dog pooping peach pits. Same thing if you need a balance or have a bad tire.

check subframe bushings...check driveshaft, check driveshaft coupling, check rear axles.

I have the exact same problem, but mine shakes real bad in 1st gear around 5-15mph. I'm pretty sure it is the transmission itself because if it was the driveshaft it would shake all the time. I have also changed the transmission mount and it did nothing. There's a bearing in the transmission that is probably worn out.

New tires can be defective. You need to learn how to look for belt seperation or lumps. Ever plug them?

Also, check your rear shocks.

When you say "shake" do you mean wheel hop? If so then...

Youre problem sounds like a bad u-joint on the drive shaft. like its binding up man check it because you dont want the drive shaft letting loose on the road somewhere
