2013 Silverado four-wheel drive 130k with the 4l60e I've already changed the fluid and filter and I noticed when I'm driving around town with ambient temperature around 60 70° f cruising around town my temperature will get up to 180 on the transmission is this normal or should be concerned about maybe possible slipping it doesn't feel like it's slipping I have a scanner that's capable of reading transmission live data I just don't know how to do it I've tried to watch videos is there anybody out there that would be willing to tell me what parameters and pull up to see if my transmission is slipping and possibly read it for me if I post it on my YouTube I don't know somebody told me that just cruising around town without working the transmission or pulling anything that 180 is kind of hot

I think that is normal, if you have the trans cooler in the radiator it will heat the fluid to the same temp as the coolant. you can add an auxiliary cooler after the rad cooler or just by pass the rad to the auxiliary to run cooler

If you have to ask if it is slipping, it isn't. Your temperatures are quite normal for the OEM set up. Would it live longer a bit cooler? Likely. Something under 160 F is perfect. Under 175 F sustained is tolerable. 

 

Coolers in the radiator have been pretty standard since the early 1960's.

That thermostat will get you in the ballpark without adding a cooler.

I have a new radiator on the way I ordered the CSF radiator with upgraded 1 and 1/4 inch core supposedly it has better cooling capabilities and I ordered the CALORSTAT 180 thermostat basically because I've had a lot of issues out of motorrad hopefully i see good results if not I'm gonna go get a tune and have the fans adjusted to come on sooner

Are you sure you don't have a 6L90 transmission that came in the HD pickups?  The 4L60 is light duty.

OP has a 4.3 or 4.8 if they have a 4L60 in a 2013.  6L80 was 5.3 and 6.2 for 2009-2013.

This is an HD section of the forum, that is why his comments were not making sense to me. The 6L90 was the only transmission during this generation of HD's.

      Brand new to this forum. Questions about re-gearing my 26’ HD

      By chris21 · Posted

      37's would probably fit with a 3" lift. GM only has two gear ratios for these trucks 3.73 for gas and 3.42 for diesel. And they can't be programmed for anything else at the moment. The rough country module just corrects the speedometer and odometer to adjust for tire size it's not a programming device.   You haven't said if your truck is gas or diesel, but for a gas truck the 10L1000 with 3.73 gears has a lower final drive ratio than the 6L90 it replaced would if it were swapped to 4.10s. GM used the same 3.73 gearing in 6 speed gas trucks. I don't think you'll have any issue running 37's with the 10 speed other than the reduction in mpg and towing/weight capacity which is as much of a function of the lift as the tire size.

      Actually, it probably was the brakes.  It's weird the way the messages came across, but I took it to the dealer thinking that something was wrong with the sensor and in fact, the rear brakes were shot.  What I don't understand is why the messages never said, your brake pads are low.  First I got the message I posted above, taking about new pads being detected.  Then I got a message saying that the system needed repaired.  It never said, change your brake pads.

      Lets Talk Z60 Suspension

      Did the KYBs keep it the same height in the front? I was concerned that pre-assembled assembly would raise it up an inch to standard non-z60 height.. I guess which it would make the rake 1 inch instead of 2 inches.

      Thank you for keeping the train on the tracks and for a thoughtful engagement. I enjoyed the reflection on a previous stance to refine and improve your position. I like that inquisitive flexibility about you Atlas.    No the process isn't sterile. Hundreds, perhaps thousands of miles of piping, vessels, pumps. Chevron, the people I worked for, were keenly aware that there is a market for what is known as their "ISOCLEAN" line of lubricants. These are lubricants that are the same as those sold bulk that are further processed by filtration to a level your particular application demands. They will filter and package and provide lab documentation as required. Do not kid yourself. Every gallon of oil that goes into a Chevron Turbine, reciprocating compressor, generator is prefiltered and tested before being charged. Lest wise it was when I was there in the plants I worked in.    There are requirements set by manufactures for the cleanliness of the oils used in their equipment. OTR such as CUMMINS has standards shared with customers on this. Commercial interest selling to Ma and Pa do, but don't share that information. Not even upon request but internally, they do exist.    The GM study sited, (Graph from Machinery Lubrication in previous post) only shows "relative" importance.  I find that fascinating. By constructing the graph like this they admit there are dozens of factors in engine life and via scientific method determined the effect of 'relative cleanliness' on engine life not in miles but in 'FACTORS'. This allows a certain amount of reverse engineering does it not?   They even provided some touchstones. Beta 75 as a reference point. Wonderful stuff!!   Smaller blenders CAN and some DO take the time and effort to do better than a refinery or large bulk blender, like Warren Oil, in improving the "in the can" cleanliness. No I don't have a list but testing could generate that information.    Again, but one of several levers we can pull to improve engine life. The simplest is keeping a clean work station while doing your own oil changes.
