I needed to replace my cluster in my 05 Silverado Z71 1/2 ton(not HD), so I ordered one with the trans temp gauge.

Anyone else done this?

How long does it take your temps to start reading? I just went for a short drive(maybe 10-15 miles) after installing it and temps around 125-130 at highest.

What are the normal temps you see? From what I've read 175-200 is normal ops?

 

I have an 08 and unless I'm towing, it doesn't get to hot. I think the high is around 150 - 160 unless I'm towing

 

Exactly..

 

Mine is 145-155 all the time while driving. Towing, not sure, dont have the boat yet!!
