2018 Silverado 1500 LT (6L80)

I just found a spool of red cable I had in the garage. Any generic cable should work, just make sure it's the right gauge. The ones they sell in Walmart auto section should work.

Yes. It pretty much covers the area from Quebradillas to the eastern end of Aguadilla, with most of the pool already in Isabela by the early 1800s.

@@vegajay Good! Then they got it right. Thanks for sharing your results.

Looks like it was, in fact, the ACCT. Even though I had done the Grambo trick, I guess I hadn't turned it enough. I gave it an additional 1/8th turn in and the noise finally went away. I guess I'll keep doing that until it no longer works and then switch to MCCTs.

Still works. I don’t use it as much because I bought a truck to pull my boat. But still shifts perfectly. I’m saving it for my daughter for when she gets her license.

@@vegajay Thank you for the response and that’s great to hear! I was also curious if when you were using a power supply for testing the position sensor voltage if you read the current draw? I’m worried if there needs to be current protection for the 5V input in case the variable resistor inside burns up and shorts. Do you know if there’s circuit protection inside the MP transfer case? Edit: Just watched again and noticed it disconnects when not in park and is protected by the fuse for the cigarette lighter/accessories. Probably not as issue if it’s lasted this long then! Thanks again for taking the effort to make these videos and I wish y’all the best!

You may have a stored engine code, if im not mistaken, it wont trip the CEL but will store it as a malfunction

My question was did you get any kind of code or sel?

@@Gixxagera got a check engine light but never had a problem with the truck I’ve put it back in bc I got a ranchhand full bumper replacement so the light bar is mounted on that but never had a issue

Wow, I just saw this. We must definitely be related as you have both Vega AND Juarbe. Are you on Ancestry? I'm registered there as jaytango.

I did, runs 30-40 degrees cooler

@@jatmomdadjt8744 did that make more difference then the shutter delete? What all did the shutter delete accomplish, benefits?

@@neptunepoolsserviceandrepa2529 I haven’t done the shutter delete on mine yet but I am planning on getting a B&M deep transmission pan and mishimoto cooler in the near future as well as 4.56 gears since I have 35s on mine.

The solenoid wasn't the problem. Replacing it would have done nothing. The $5 diaphragm was the issue.

Resell is a good thing to think about but I’d value knowing a cars full history in regards to the engine and tranny more important than gambling on a vehicle just for 4x4

Que motor tiene tu jepp, 3.7 o 4.7

Yes. I installed the Sure Cool thermo bypass a few months back. I did see cooler temps, but not as much as some of the guys on the Silverado forum. But then again I live in FL, so it gets pretty hot down here. It still gets to the operating temps of the 190s but it takes longer to get there. I haven't installed an aftermarket trans cooler yet. That's probably my next step. Also, to change the trans fluid and filter. I just 30k miles so I think it's time. BTW, I towed my boat last weekend on an hour and a half ride (21ft Sea Ray, dry weight 3,500 lbs + trailer) and highest it got was 205 degrees.

They're designed to close at higher speeds (55 mph) to reduce drag and make the vehicle more aerodynamic, if they detect any type of over heating they open back up on their own. This mod pretty much just made a higher end vehicle like the lower end vehicles that don't come with this option.

@@hdrolling The problem is they fail and then they won't open or close. You don't need this option, it's junk. All it does is help emissions and mpg.

@Jose Duran Jr "Why would you deter what the engineers factored into design?" Have you seen all the TB, TSB, class action law suits against GM and their transmissions? Just the 8 speed alone has 60+ TBs over the past few years. GM tried to have one of these class action lawsuits thrown out claiming that the transmission problem are related to a design defect and not a manufacturing defect. Excerpt from an article regarding one class action suit: "GM has argued that these claims should be thrown out, as its express warranty only covers defects that relate to materials and workmanship, and not design defects. The suits claim that all 8L45E and 8L90E transmissions experience these problems, which implies the problems are related to a design defect instead, the automaker said."

@@14burrito2 This is JUNK. it doesn't do shit, but get your car warmer quicker in the winter. If you care about Aero Dynamics, you buy a sports car, this is a damn truck. The engineers love to "OVER ENGINEER" shit. This is Crap. My vehicle is a 2017 GMC Sierra, it has 82.000, and this broke (error U1510). I took a different approach, and used a Adruino and C++ to emulate the motor. In MA, the vehicle will not pass the inspection with a check engine light, and this CRAP does throw a check engine light so... This will cost from $250 to $400+ depending on the dealership's location, markup, etc, etc.

I deleted mine because in freezing temps they stay shut at speeds above 50mph. That’s a problem when you have a plow on the front of the truck that limits airflow to begin with.

To be honest, pretty meh. I expected more noticeable results but I barely saw much change. Probably only like 5 - 10 degrees cooler. There may be other issues causing my temps increase. I’m starting to see a pattern. Once I start going over 78mph, that’s when the temps start to climb, especially if I’m not going a constant speed, like when passing. Maybe torque converter friction? IDK. The other day I got to 199 by the time I got off the highway. Right afterwards, sitting in local traffic, it peaked to about 210 before finally starting to drop after like 10 mins.

@@vegajay so whats the verdic? have u since did any mods? and did u add one of those SURE COOL made by superior, FOR ACTIVE BYPASS? part #STL010 is for the 2018 silverado LT 4x4 5.3 6L80E Transmission 6speed.

Update? Did you get a code after the mod? My temps fluctuate when towing. Thinking this might help. Thanks

Try changing the stock 207 degree thermostat to a 194 degree thermostat. It made a difference on my 2018 Silverado 1500 with the 5.3 It used to go beyond 210 at high speed highway driving but it no longer does that si nice installing the 194 degree thermostat

@@vegajay Check for bugs built up between the condenser and the radiator. Mine was literally packed. What’s the current update on your normal operating trans temps?

I have the same problem on my 2019 temp goes up when I'm going 80 on the freeway and also noticed once trany hits 200 it starts shifting hard. It's a new manufacturer trany and shop can't find anything wrong lol idk what's going on. I just put ppe bypass valve will see what happens

You need do what I did,call the flip,go under and remove the cartridge where the thermostat is located,once you get out carefully the thermostat remove inside the pill and the spring,then insert the pill where the spring was and the spring inside the thermostat, spring is hollow so air will always reach and cool down transmission mine now reach the most 180° when towing and have to stop to much on lights

ok boomer

I think you mean "reflector".
