I've put over 100k towing miles on LMLs, my tranny temps are typically around 170. Before I added TranSynd I would see mid to hi 180s from time to time, the highest I've ever seen was 193. The temps have consistently been about 5-7 degrees cooler since doing a double change with TranSynd. A retired Allison Technician who was responsible for fluid testing has come out and stated that TranSynd consistently was the best fluid they ever tested for the Allison and he highly recommends it. My dad has an LBZ and he would see 190s pretty regularly with his, after he did the double change and added the deep pan his temps have dropped 10 degrees. It's an expensive process to do a double change with a deep pan, it takes 7 gallons at $45-50 per gallon, but it's much cheaper than a $5-6,000 transmission. BTW, the rep also said you can run the TranSynd for 100k miles, so that's actually less than one half cent per mile. Not too bad when you look at it that way. I don't actually do a double change at the 100k mile mark, I just drained the pan and dumped in another 3.5 gallons. I might drop the pan after another 50k miles and change the internal filter. The spin on gets changed every 10k miles.

With my LML I set the transmission monitor visible and notices the temp rises with the cruse control on by disabling that the temp will drop fast into the low 160 to 150s. Its got 60 K and due for a trans oil change, baldwin oil filters and I change allison trans filter every 10 K miles. I also use the oil monitor system and there is a lot of debate on that . Laredo has ask for opinions and comments no 2 vehicle are the same. I will suggest leaving it stock and do what it likes hauling.

Enjoy the new truck and let us know what 5er you end up buying.

Well I brought the truck home today. Wowwww. My biggest problem is learning all of the electronics, good thing I have teenagers to help me.

As far as modifications, I think everything will stay stock at least until the warranty runs out. As far as the tranny temps, I can't tell you what is best, I can tell you this though. My previous truck was a 2010 2500HD with the 6.0 gas. When towing thru the Big Horn mountains, the motor went to about 230 and the tranny was in the same range. We pulled over to let it cool down, checked the owners manual while setting there, it said that the motor temp was normal and the motor would go to 234 degrees when pulling thru the mountains. The owners manual also said the driver information center would give a warning when the transmission was too hot, it never did even at the 230 temp. That was when the truck had about 70K miles on it, I just traded it in with 120K miles and never had a tranny issue. I did have it flushed at 100K miles though.

IMO, leave it "stock" even after the warranty runs out. The modifications to the pan, diff cover and Edge CTS do not change performance setting and do not affect warranty. The Edge is not a programmer, it just allows you to see all of the details from sensors normally only visible to the dealership when they attach a scanner when you get a check engine light.

I have good example of it's uses: I had a EGT sensor go bad. #1 sensor right after the turbo, which is the one I have up on the screen so I was able to watch the readings go crazy then peg at 1870 degrees. The truck went into limp mode on I-10 just outside of Riverside, CA. I pulled off to the side, immediately brought up the other 3 EGT sensors, all were reading in the 600s. At that point I was confident that I had a bad #1 EGT sensor. I was able to reset the check engine light and erase the code taking the truck out of limp mode. I called the Chevrolet dealership in Palm Springs, they had a sensor in stock and would work me in since I was traveling. I went in, told them to skip the diagnostics and just change the sensor. I was back on the road in 45 minutes. Without the Edge, I would have been stuck on I-10 in limp mode, most likely been forced to call a tow truck and pay for diagnostics. The Edge paid for itself on that one occasion. It's also nice that I can set alarms when certain conditions exist, and I can also set up maintenance reminders for pretty much everything on the truck that requires routine maintenance.

Enjoy your new truck, they are nice.

Edge makes a nice product. Its nice to have the info and a means to deal with it. I have a tuner with an OBD reader that has saved me time, inconvenience and $$$.

Smarty makes a good one for Cummins with a mileage software option that increases mileage and power among the nine or so options available in the tuner. The ECU software can be returned to stock during the warranty period without any telltale evidence of a tune being installed.

Lots of nice options out there that provide valuable information.

My 2013 Silverado 1500 had a digital read out on transmission temp. I cannot understand why they dropped that on the 2016. Now all I have is a warning light for high temps. WTH. I have the LTZ plus and Z71 packages so you would think that one of those would have the actual temp display but no.

bsmith0404 · 08-22-2016, 04:06 AM

An aftermarket product such as the Edge CTS would give you the ability to monitor the temps, set warning alerts, and maintenance schedules. It still has a sensor (obviously with the light) so the ability is there, you just need the gauge.

The dumbing down continues. Maybe someone will develop a smartphone app...

Can't agree more. We have the OBD II for our powerstroke. Bluetooth connection to my Android. I got it so I could monitor EGT on a long pull. Love all the other info such as being able to monitor coolant temps in both cooling systems as well regen intervals. It can even enhance the OEM TPMS. Love this technology. Originally was going to go with some after market A pillar gauges, but my DS told me about the OBD II - very happy with it.

Are you sure it's not a menu item that is currently not selected for display? My 2014 didn't display it at first and then a salesman spent about 1/2 hour with the book and truck figuring out how to get it to display. Hope that's the case for you too.

Laredo291OH · 08-22-2016, 06:44 PM

My 2016 3500HD Silverado was the same way, I had to add the trans temp to the display in the gauge cluster. I was surprised to find that my 3500HD SRW doesn't have TPMS. Apparently if a vehicle is over 11000 GVW it's not required, the SRW 3500HD with a Duramax has a GVW of 11600, so no tire pressure monitor. Or at least, no way to monitor if it does have it. Of course, I haven't had my teenagers out there yet to show me all of the electronics. You would think for the price and what the truck will be doing, the would still include it.

GMcKenzie · 08-23-2016, 05:11 AM

I'm with tbos. be sure you just haven't got the display turned off. I can't see why they would make that change from 15 to 16.

You guys were right, even the dealer (Toyota dealer who owned a '12 GMC) thought it was missing. He said his uncle bought one and commented on no temp gauge in his new truck. It is there, just like the video that GM supplied. One exception is that mine doesn't have a settings mode, you just got to dig deep in the Information mode. Thanks gentlemen, much appreciated.

Tbos · 08-25-2016, 03:31 AM

Glad you were able to get it to show.

GMcKenzie · 08-26-2016, 07:33 AM

Will say it is one thing I'm disappointed in in my truck. Last truck I had an Edge CTS that I could configure to show up to 8 items at once. I wish the DIC on these things was more customisable. I'd like to see the speed screen with temps on the sides, V4/V8 mode on the bottom and something to show the actual gear you are in (which I can't get at all). Instead of having to flip from screen to screen to see temps etc.
