Mine does that. I'm told it could be the shift forks, since it also "pops out" of second gear when decel-ing. Hope that helps. Edit, I have the 5-speed MTX, if you run a 4-speed ATX it could be totally different.
If you have buzzing sounds in your ears and head it could be indicative of tinnitus. The most common cause of tinnitus is due to hearing loss as a result of excessive noise.
The speaker could be buzzing for a couple of reasons. If the signal from the radio is causing the buzz then you may have to replace the radio. If the speaker cone is the cause of the noise, then the speaker will need to be replaced.
the transmission could be going out or slipping or your transmission fluid could be low
A bad motor can cause a buzzing noise in your 1997 Mercedes E420 rear-view mirror. If it has a light, the light could also be going out.
Having too much fluid will cause your transmission fluid to look foamy
yes it would cause the gears to slip more or less
IF you have over filled the transmission this will cause it to bubble, this could cause serious damage, drain and refill with the proper ammount.
Short to ground.
your transmission is most likely bad if it an automatic but if it a manual then your clutch could be bad
shifter cable, low transmission fluid or faulty transmission.
your cluch could be gone!
There is no such thing as "transmission oil" there is only transmission fluid, but but over filling the reservoir could cause serious damage to your transmission..
