Noisy early morning transmission ?

[James Ward]

Hi, Are all these 6 speed transmissions so noisy at first in the mornings ? Seems kinda strange to me, my 1990 Chevy Silverado 700R4 is quieter than the 2015 Tahoe !

The 6 speed transmission in my 07 Yukon XL Denali is not any more noisy at first in the mornings, than at any other time in the day. In fact, I don't notice any noise from it at all. Perhaps, it is because I have a loud exhaust system, and I'm just not hearing the noise, but I doubt it.

Other folks will chime in with their opinions and experiences.

if you let it run a few minutes before putting it in gear does it help? or does it make noise even when in park?

Ah, not really. but it does get quieter later in the day as it keeps warming up.

Never noticed any difference in any of the 6 speeds in our vehicles and we have some cold mornings here in Iowa, much like you can have.

James, what kind of noise(s)? I can't recall ever noticing mine making any kind sounds. Maybe they are drowned out by the transfer case and front differential!

Never noticed any noise in my 6 speed transmission in the cold weather when I was in NYC in November and December.

Hi everyone, Yeah it's a whining noise, I don't know if it's high or low, it is just there !

Do you happen to be in 2wd or 4x4 auto mode?

Mine makes a very soft quiet planetary whine when in 1st. I figured it was normal since I have heard other trucks I have owned do it too.
