I installed the updated by-pass module on my 2018 Silverado 6 speed transmission. I haven't found a way to insert the dip stick without it binding in the tube and I end up twisting it and jamming it in. Is this normal? I got so frustrated with it I had to walk away, as I must have attempted a dozen stick checks and none seemed to be the same.

I did add some fluid as I lost some switching the by-pass module out. 

Is it normal or do I have an issue?

At least you HAVE a dipstick. Don't even have one on my 8 speed and checking the level involves jacking, leveling, wrenches, and calculating temperature algorithms!

Look into something like this: 

During my research, I saw people doing to the 8-speeds on Camaro's and such. Last resort try a commercial option. As in, the HD drivetrain is in some funky cabover Izuzu service truck and has a dipstick. Worst case, there IS aftermarket tubes/sticks you can get from Lokar and others. Expensive Example .

Don't forget the slide rule.  😄

Yep.  Gotta get it to slide in just right.  There's a sweet spot where it just drops right in.  Try to feed it with one hand holding the handle and the other hand feeding it in close to the tube.

I can’t think of a time when I needed to add fluid in the transmission. Except when changing. I rather have a dip stick. Most times people don’t get the fill right. If you have to add there’s a problem. Usually you can see that on the ground. So I can see where a full hole would be an advantage. No guessing.

I have tried to duplicate that "sweet spot" and that is the difficult part... I am not able to... but I understand what you are saying.

My issue was when I originally did the pill flip I lost some fluid, not much at that time so I didn't add any. Then I went ahead and installed the updated by-pass module because I live in Ohio and was concerned that the trans may not get up to proper operating temperature in the cold winter months. So then I did notice I needed some fluid, or so I thought... the dip stick is a pain and hard to get consistent reading for me.

Original I overfilled and pulled some out with my Mity Vac but it just seems for me its hard to get consistent readings.

Sometimes when I can’t get the dipstick to go in all the way, I pull it back out, flip it  on the other side and then it will go all the way in.

How are you checking the trans fluid level? Are you warming it up first? 

 

And just to add, whether the pill flip or changing out to updated thermostat, very little fluid gets lost. Where you do have to worry is when you change out the thermostat, then don't replace one of those little orings for the lines, and take a drive down the highway. Then you will lose quite a bit..😳

The best way to answer this is I get different readings... I must have checked 20 times... It is hard to read the stick as I did have the trans flushed and fluid is new. I was checking when trans was warmed, 120 degrees if I remember correctly. One side of the stick showed a different level so I am thinking it was getting wiped off as I was pulling out the stick.

Just now happy with the reading I was getting. 

Then I added a pint or so and it seemed then over the full mark. 

Frustrating

I don't think 120⁰ is warm enough. IIRC you need to have the trans warm enough so the thermostat is open. So with the updated one, it would have to be over 158⁰.

That may be a problem. Drove a good 110 miles the other day and never got above 144

I’ve had that issue too. When my trans won’t get up to 160F, I either drive in a ton of stop and go traffic or I take it on back roads and start doing some hard pulls until it’s up the temp.

 

Also, the temps for a hot check are 160F to 200F.

Not the best way to do it but what I did when I had to refill after my unfortunate mistake, I was a bit in a hurry and needed to get it done. I did the cold level check, then cycled slowly through the gears, then with foot on brake and in drive, I kept pushing slightly on the gas, letting off, doing this a number of times until I got the temp to go up to where I needed. @steelerdude15 also has good tip of a lot of stop and go, think city traffic with stop signs and lots of traffic signals. This will get the temp up. Simply driving along, even 110 miles will not do it.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.
