  • I changed the fluid and filter on my 2016 Sierra to stop the shuttering and improve the shifting. This should be the same for all 8L90 Transmissions in Silverado / Sierra / Tahoe / Denali.

    Well, I finally got around to doing it. Followed your video to the "T" and the shudder is completely gone. Runs like it did when I bought it and the shuddering was absolutely horrible. Thank you very much for the video...In case any other readers are curious, I have a 2016 Chevy Silverado LTZ (5.3L, V8)..
    The transmission filter and amount of transmission fluid to put back inside the transmission is the EXACT amount as shown in this video...

The only 😊problem I had was finding the Mobile 1 Blue Label Fluid. Couldn’t find it anywhere. Amazon shows it available but I gave up on them after 10 days. So,I went to my local Napa Auto store and purchased Valvoline Full Synthetic ATF Dexron VI and Mercon LV. Viola! The results were better than when the truck was new😅. No more shudder and no more load up hard shift between 1st and 2nd. After reading some of the repeat shuddering with some of you, I am hoping this will last.

    Nice job on the video. Many GMC and Chevrolet dealers back in 2016 to 2017, were buying back Trucks and Cars with the 8L90 via the lemon laws. Every state has different lemon laws but GM was buying them back due to the multiple repeat repairs without resolution. This was all because of the Torque Converter Shudder. I remember the dealership I was at originally used the Mobil 1 Black Bottle Fluid, only to have trucks and cars return in like 3000 miles or less with the same complaint. As I recall the Mobil 1 Blue Bottle Fluid came out in 2017 or so and resolved the Torque Converter Shudder immediately and no return complaints. Somewhat surprised you were still able to buy Black Bottle Fluid, as I remember the GM dealers in my area were instructed by the zone office to discard any Black Bottle Fluid due to some dealers still using it and creating repeat customer complaints.

    FYI - GM stopped asking dealers to emulate a shudder with pico gauge around mid 2019. Ask your dealer to ref latest version of TSB 18-NA-355 and all you have to do is present your vehicle within the remaining powertrain warranty, tell them you think you have a shudder, and they will triple flush your transmission under warranty. In a Corvette, that's worth 24 quarts of new blue-label Mobil1 LV ATF HP. This is a GTL group 3+ base stock with a special additive pack from Infineum, which is a joint venture between ExxonMobil and Royal Dutch Shell Chemicals.

    Appreciate you posting this. Just a quick heads-up... trans temp is supposed to be between 95-113 for fluid check per GM service manual. Also, if you still have the thermal bypass (thermostat) they recommend to bring it up past 190 initially to cycle the fluid through the cooler lines and then let it cool down to check per the above temps. Obviously if you've deleted the thermostat you can simply check when it's at the above range. Great video!

      let me know how it does long term. All these trucks will shift perfect at first with any fluid change but the problem is the original fluid was hydroscopic and would induce moisture and cause the problem. The new blue label is anti-hydroscopic, so it is supposed to fix the moisture problem. I am not sure about amsoil.

    Did this tonight. I had it flushed several years ago by the dealer before they started using the blue label fluid and the problem came back. Basically parked it for a while or just 'drove around it' by getting to know how to work the throttle.
    The dealership put the drain bolt in so tight I bet it has 80+ ft lbs on it and it stripped. I could NOT get it off. So now I'm sitting here with a stripped bolt on the bottom of the pan and the trans filled until it came back out the filler hole. Think I'm going to drive it a couple miles to an oil change shop and have them get it out. Probably going to need a new plug though. Arrrgh.

    I actually like the easy of doing simplicity of doing a flush on my 8l90. After I shut the truck off and while hot, I opened the level check bolt. 2 quarts came out. Then, I went around and broke loose all the pan bolts. It was more start forward than the 4l60e. 4 quarts in the pan. No issues with the exhaust like I thought. Just yaw to the passenger side. Changed the filter and cleaned everything. Not too messy. The fill... I pump until fluid came out. Started the truck and kept pumping until it was just bright red fluid coming out. Check the temperature and let it dripple and closed it up.

    You should compare Mobil to Amsol fluid. High reviews for Amsol. I have a 2018 Silverado 6 speed. Transmission thermostat causes oil to heat up extremely high before it will circulate through cooler. Newer models have been fixed. I swopped out thermostat with Surecool bypass and what a difference it made. Temperatures now run the same as 2020 models.

  • @dealsfromvirginia1773
    @dealsfromvirginia1773 Před rokem +2

    I appreciate your hard work on this vid but I'm pretty sure your fluid is low. Considering you drained the cooler and lines, they never filled unless you had previously installed a bypass for the trans thermostat. That thermostat does not open and allow fluid into the lines and cooler until the trans reaches 190 on older models, or 158 on newer cooler lines. I'm glad your shutter is gone and wondering if you have any updates considering this vid appears to be about 2 years old at my viewing.

    At the 35:00 when u removed that screw, that oil coming out is excess oil? I didn't understand that part, you should do that after a fluid change so it levels it up to the perfect level? Please If u can explain, thank you.

    • @737mechanic
      @737mechanic  Před 2 lety +4

      That screw has a stand pipe so when you fill the transmission with fluid and warm it to the proper temperature you remove that screw to let any excess drain out, once the excess is drained it will be at the perfect level. If you take that out and nothing drains out you need to keep adding fluid until it starts draining.

    I also installed the STL010 in my 8L90 along with doing a filter (while changing temp sensor) and adding blue label. Keeps the 8L90 from opening up the thermal bypass at 194 and gives you an instant fill of the cooler. Keeps my temp around 155 at all times even in the heat of July.

There was an unrelated warranty repair on the temp sensor harness about a month later, which requires removing the pan. Maybe they used the black label stuff by mistake? I don't know.

    So I did exactly this a year ago and it fixed my shutter. However after putting about 20,000km the shutter is starting to come back. I'm going to be doing a flush again and hopefully it takes away the shutter again. What I am assuming is there is still old fluid in it from the previous flush that just causes the shuttering to some back. Hopefully with another flush it will dilute the old fluid more and eliminate the problem for good.

    The 8 speed in my 2018 6.2 Sierra was very smooth shifting and never experienced the shudder. At 30,000 miles I took it in to my local GM dealer for the new updated fluid exchange and transmission filter change as preventative maintenance. First thing I did not like is that he did the fluid exchange with the flow tech machine before dropping the pan and cleaning it and changing the filter. Now I have a slightly more firm shift from 1-2 and down shift from 2-1. Also, it seems the down shift from 2-1 is a bit lazy. Maybe he knocked a solenoid loose?

    I have a 2015 gmc sierra denali 1500 4x4 5.3
    my trucks problem is that when I accelerate between 0-20mph the transmission kicks/shakes it feels forced. I have to release the gas petal and step on it again slowly. is that transmission fluid recommended for my truck? Thank you for your help!

      If it is an 8 speed it is for sure if it is the 6 speed I am not sure.

    Does this technique of fluid extraction pull the old fluid out of the torque converter?

    • @737mechanic
      @737mechanic  Před 24 dny

      No, the only way to get all the fluid is to do a fluid flush.
