2 simple questions.

Tried searching to no avail. Could be the tapatalk app

Anyway. Looking for the size socket needed for wheel bearing and the torque spec of it. Also. The 3 nuts in back of wheel bearing/hub assembly are what size?

What is normal operating temp of the transmission? I was sitting 150-160 in 80 degree weather.

Can't help in the wheel bearings, but I think that's about right for the Trans temp. I want to say mine doesn't get over 160 even in 100 heat. Unless I'm sitting idling for long periods of time. But I haven't checked it much since I added an external cooler and electric fans.

How are you checking your trans temp?

Denali's and 2500's have Trans temp gauges in the cluster

Nice! I'm considering adding a trans cooler in the near future. Would be nice to figure out a way to monitor temps.

I have a bluetooth OBD2 reader, when Im towing I use the Torque app to monitor temps.

I added a Derali cooler to mine. simple and cheap. anything I can to do help prolong these crappy 4l60e's

Sounds cool! You have a link to the Derali cooler? Maybe I will install myself instead of having the trans shop do it.

And I wonder if that OBDII bluetooth device could interface w/ my head unit. That would be sweet!

Which cooler did you use? My 33s have raised my trans temp, I was running 160-180 today in 90 degree heat.

Pretty sure it was that one. With the GM snap in radiator fitting. Literally a 20 min job. But you will want more hose than what comes with it. I was able to make it reach, but just barely. I'm running 32's and have towed 5000lbs in 100* weather and it never got hot. But I really don't remember what the Temps were. Been a while.
