Grumpy,

I think if anyone has the answer to this question it would be you.

My question,

On average how much does transmission fluid expand when it gets warm. I ask because the new transmissions without a dip stick are checked at a specified temperature to allow for expansion I believe. Remove level plug and fluid drips or slow flow at specified temperature. 

Just curious.

Of course is depends some on system volume and shapes but if you pull the stick on say a 15 6L80E or older 4L60 you will see to marks labeled 'cold' and 'hot'. It's quite a bit different. At the end of this members really good video he explains the level check on stick-less systems. Level and within the temperature required is key.

Confused.

I know about checking the fluid level on a trans without a dip stick. I have done it. I was looking for a number for average expansion of trans fluid. 1% 2% etc. Thought you might know.

Ops my bad. Misunderstood. It is knowable but I'll have to look it up.

Note, the difference between the hot and cold marks isn't solely due to fluid expansion.  At least for my 4l80e, GM has a process for shifting through all the gears after warming up the fluid to distribute the fluid throughout the transmission, whereas the cold mark is just to make sure there's enough fluid in the transmission to function so it can be warmed up to do the fluid level check with the hot mark.

0 ounces of make up oil. 

 

I'm calling this one a  quart in 20K ++

This would be better than the engineering standard for this fuel/mile distance of 2.5 to 4 ounces or 0.03% to 0.05% of the fuel used over this OCI.

Just curious but why add make up oil if you are going to change it out real soon?

Great question:

 

To quantify the usage.

If I can measure it...I can graph it....

If I can graph it I can fix it....IF it's fixable.

 :)

 

It gives me eyes, statistically, into what is going on and how my changes are affecting the situation. Even if I fail at a fix, it keeps me from making the same mistake twice.

 

😉 

 

Oil companies spent allot of money on my education in stat's and process control and I saved and made them millions working this system. Time for me to benefit from that training, eh?

I'd love to see the TAN and TBN numbers 😉

At least you put the plug in before you filled it :). 

 

The TBN/TAN numbers in this post are for the diesel in the last post, correct?

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.

      Let me know how your vehicles do in 10 years. You don't know ******, kid. 😂    There's a reason that Panther platform was used as police, fire, and taxi service for DECADES ... long before you were born, apparently.

      Disconnecting Battery

      By davester · Posted

      If your connector also has a big lever to get the connector on and off, you don't want to force the lever either way, as it becomes a bigger problem if you bust the lever or the mechanism it works.

      Disconnecting Battery

      By davester · Posted

      It's just useful to disconnect the battery to prevent odd shorting out when unplugging/plugging stuff together.  I also  touch the two cable ends together (after disonnecting) to drain the small amount of stored battery energy in various modules.   I believe the main system where you need to be more concerned with, so you need to do the above and then wait some time, iss when you are working on the air bag system, to prevent inadvertent firing of the air bags.   The in-cab switches are just that, plain switches, it's generally not a problem to swap them in/out.  For my '12, I'll get an error message on the dash if I power up the truck w them unplugged, but that's it (power up= turn the ignition on).   The ITBC located above the spare tire is a computer that manages the trailer brake system.  That is probably more important to have the battery disconnected.  It does have to be programmed to the truck, either before or after it's installed, for it to work.  For my '12, I had a very hard time reinstalling the main connector to it (IDK if yours is the same or not), it turned out the silicon seal was jamming up, preventing it from going on all the way.  I finally got it fully installed by lubing the seal with a bit of dielectric grease, then it slid on and latched in place easily.

      Remote Start Noise 2024 2500 HD Gas

      By BCGM · Posted

      JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course   it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold  . Keep tuned !   Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do , I will see if I can find it and post it up
