I have a 96 Civic EX sedan, automatic (unfortunately) I have a weird grind noise mixed witha buzz coming from the right area of the engine, probably from the transmission. Here are the facts about it.

• Only buzzes at 2k-2.5k RPM
• Louder with more acceleration
• Slightly lower with deceleration
• Loudest in the lower gears

Again its more of a Hollow sounding grind mixed with a buzz, coming from the transmission area. The Transmission performs normally other than seeming to have a 5th gear at cruise... It also tends to bounce one time, downshifting from 3rd into 2nd when accelerating out of a turn.


Thanks ahead of time. ~ Austin

Checked the trans fluid, pink, correct level. Transmission is also automatic.

Buzzing is still there :|

Only until I pass 2.5k RPM

If it were a constant noise that only got worse, I would suspect that. I just cant figure this out. The sound is somewhat hollow, but like a grinding-buzz.

Of of like when rotating fan blades at high speed just barely make contact with the cage surrounding it.

Rpm range changed.

Now it buzzed at a cold idle, 1.4k rpm and up to 2k rpm. Afterwards does not buzz...

This is starting to freak me out
