No Tyme

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

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

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.

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.

Just replaced mine last week, with an LED bulb, and the cargo lights also. Also sealed it up with silicone

I have to step into this thread and ask... AC Delco Dexron VI is a FULL synthetic which is what the dealer uses, but you can by Castrol brand Dexron VI that is a blend... does it hurt to mix these two? This doesn't make sense to me that Castrol would state this is for GM vehiecals.

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?

I traced the ground cable from the battery down to the frame, which is just behind the passengers right front wheel. I cleaned that contact and haven't had an issue since. I have read there are issues with both positive and negative cables but for now just cleaning that contact has worked for me.

Thank you for that info. I will see what happens as only time will tell if I still have an issue.

When you post "Bad battery cables" do you refer to both or just one of them?

New battery was on charger all night, it did start today but it randomly will just click once with the turn of the key. Looks like my issue may not be solved yet. Any grounding issues I should consider looking at before I spend money on a starter?

I put my battery charger on it, charging at 8 amps, dropped to 7 amps after 10 minutes. Maybe the new battery needs charged... manufactured dat 6-22

My 2018 Silverado has sat in the barn for several days and I went out to start it and all I get is one click. Turn ignition off and try again, one click. Took battery to NAPA and they tested the battery, and tester said replace battery. New battery installed and same thing, one click when I turn the key... not sure where to look next. Don't think I need to reset anything... so ideas please.

At 8500? do you not drive much?
