Humming during acceleration

[laynbdyon20s]

I noticed it while driving to Vegas from Los Angeles. I hear a humming coming from the front passanger side, and it "hums" when I accelerate. If I let off the gas, but still in gear, it goes away. It is a pulsating/humming noise. It seems to do it in every gear. If I take it out of gear it goes away.

Symptoms:
1.Only during acceleration
2.Any gear
3.Does not do it during deacceleration
4.Does not do it in nuetral

Check trans fluid level. And while you’re at it change trans fluid. Could be a number of things. Start trouble shooting start with the simple cheap steps first.

Changed the tranny oil, noticed no metal chips or anything. Humming is a lot less noticable but still there. Perhaps the bearings are on there way out?

Did you figure out the problem? I am having the same problem with my 97 gsx but it just happens in 2nd gear. The pulsating hum goes faster as the rpm climbs but as soon as I push the clucth in to shift to third, its gone. Even if I am in 3rd at a speed that I would usually been in 2nd its not there so thats how I know its just 2nd gear.

Yeah I figured it out. My tranny went out. I thought it was my differential that went out, but I got an email from jackstransmissions and Jon said my 4th gear broke. It's currently being rebuilt.

That sucks, and it was just the 4th gear that caused the humming throughout the entire tranny and all of its gears...thats weird. I hope mine does not go out anytime soon. Thanks

It was doing it in every gear, and only when accelerating. I was in 3rd gear when it went out.
