5spd whine

Ok It looks like you just installed the tri Ax, you are hearing the tranny sound more now, that is normal with a shifter because the sound deadening boot usually wont go back on like the stocker, mine got considerably louder after the install, I took it to my friend Don at KBL transmission and all was perfect...... just louder now..
Are you getting the same vibration like you do with the stocker? If so also check the driveshaft.
 
The original one in my car made the same sound since I bought it four years ago. It kept getting worse until it sh1t out on me on the road. Turned out to be a bad seal causing the fluid to leak out. Wore the main shaft and bearings. My opinion? Keep an eye on the fluids until you can get it rebuilt/replaced. I bought a new one from tommy vaughn a few months ago and no problems since, dead quiet with a mgw shifter.
