Trans Temp ??????

[paulv]

Does anyone know what the trans temp is supposed to be in the 2014 Silverado? Mine is 198 degrees. My truck is brandy new and I love it.. I came over from odge.

[VMaxtastic]

Its normal. Scared me at first too. If you take a look in your manual, it will tell you the operating temps.

Perfectly normal at 198.

Thanks,,, I read the owners book and it says 160 - 200 for hot oil check. 198 seems really hot for a transmission,, but I only have 218 miles on her. Do they come with a cooler or should I look into having one installed? But I have to say,,, she is much smoother riding and quiet compared the Dodge I divorced.. The definition for " Dodge " in the dictionary says " to avoid ". What was I thinking???

They have a cooler. All GM pickups do. They have a thermostat that bypasses the cooler until a certain temp. Hot fluid is thin fluid. Thin fluid helps fuel economy numbers. I personally prefer to have a cooler transmission.

The 6-speeds run warmer than the old 4-speeds but they also use a synthetic ATF. My 2011 has been up in that area plenty of times and 62k miles later is still going strong.

I left Dodge back in the early 1980's, don't plan to go back.

 

I'd just leave your trans alone. The main issue is towing in hot weather, if you plan a good bit you may want additional cooling.

GM makes no claims its Dexron VI is synthetic. Where do you get that information?

 

 

Just remember: GM only HAS to worry about 100,000 miles...beyond that; (1) it's YOUR problem, (2) they're off the hook, and (3) the stealer-ships MAKE money replacing expensive parts.

Dex VI = synthetic blend

I read it on here.

 

I did a quick search and it seems several of the aftermarket ones that meet the spec are synthetic. Not sure now. Not that it matters since the trans running 200* is a non-issue.

From I can tell from this MSDS, this would be considered a synthetic blend

 

Hydrotreated base oil would be a Group 2

Hydrocracked base oil would be a Group 3

 

Group 3 oils are considered a "synthetic" from a marketing standpoint but not by some purist. Group 3 oils are derived from crude oil but have gone through enough processes to be considered a "synthetic". Almost all over the shelf "synthetic" motor oils contain some amount Group 3 base oil.

The 6 speed in my 2014 runs at the exact same temperature as my 2007 4 speed. 198 F is normal in the summer. If you tow/haul or travel at highway speeds for a while, you'll hit 200-205.

 

Also with regards to coolers, there's 2 kinds. One is the cooler in the radiator where transmission fluid is pumped through it up front to cool the fluid down. There's also an available external cooler that mounts to the transmission to cool it directly.....sort of like a refrigerator for the transmission. That's an extra cost option that unless you paid for, you don't have it. Most of us will not have it.

Isnt this the Z71 option?

No Z71 has nothing to do with transmission cooling. Z71 gets you (besides the aesthetic features) Rancho monotube shocks, skid plates, an automatic locking rear differential, and hill descent control.

 

The transmission oil cooler in the radiator is part of the tow package if you opt for that package.

 

The external cooler that mounts to the transmission itself is an entirely separate upgrade option that is not part of a package. Going by memory I want to say it's like a $250 upgrade but it's been a while since I've really looked into it.

[Silverado-Hareek]

I did some research and they may have changed it on these new K2 trucks to where there is no externally mounted transmission cooler available anymore. You have the standard transmission cooler in the radiator and then an enhanced version of that with the max trailering package. I was going by what I remember reading on my 2007 Silverado. Sorry for the confusion.
