    6L80/6L90 Dismantle

    I actually have a pair of those snap ring pliers. I work on heavy equipment and some of the snap rings are huge in my field. Looks like I have all I need to build one. Too bad mine is already built.

    2017 Tahoe hauls ass.....

    Blackbear is great. You can get retuned for life. Also after tuning if things seem off or not right they will answer your concerns and modify your tune to get it spot on. They use data logs you provide to customize the tune to your specific vehicle and how its running. Its a simple process...

    Window Tint Pictures

    cant speak for him but here where I am at in Alabama I would be nailed non stop for having tint anywhere near what any of these pics have. It sucks but its the biggest reason for a ticket around here. Makes most of the income for the local cops and troopers. Loud exhaust that is annoying its...

    Transmission Sounds Lower RPM - UPDATE

    I can rebuild them but I paid someone else for the warranty purposes lol. But dropping it is easy. Remove the Y pipe, starter, shields and harness, removed the rear trans support and driveshaft and lower the trans down to get access to the center top bell housing bolt, remove the rest of the...

    Transmission Sounds Lower RPM - UPDATE

    16 hours to take it out??? The hell are they smoking. I took my trans out and put it in myself with no lift in my yard in less 8 hours and used my body as the trans jack. If a tech at a dealership with a lift and trans jack takes 16 something is seriously wrong. Also 5k to rebuild is a joke...

    2015 Yukon 6.2-Listen to this noise- dealer says $5k for new TX

    You very much so should drop the pan. The filter should be changed on any normal trans service. Also on the case of these newer vehicles there is a thermostat in place on the cooler lines. Until the trans is above a set temp those lines are not even flowing. Fluid bypasses the cooler at the...

    Jacking a 2017 Tahoe

    As the image above shoes there is a pad welded to the axle to use as a lift point for either side. You can lift at the center if wanted to pick the entire rear up.

    Tune voided my Yukon warranty

    If your changes have 0 effect on the parts failed as in it literally did not or could not cause that failure then yes the MM act can protect you. At that point the failure is still a FACTORY defect. Yes if you up the redline then throw a rod or wipe a lobe that is on you. But if you say tune...

    Performance Spark Plugs and HT Leads

    This people counterfeit spark plugs way more than you would think. Its bad in the rotary engine market. NGK fakes are more common than any legit plug.

    Sudden movement when truck is parked and off

    was told it was normal operation and they would not fix it. I figure the shoes are were out of adjustment for the park brake since assembly. Its so rare I have to worry about it anyways. If im ever parked on a hill I always just slowly release the foot brake so that it gently catches the park...

    2015 Yukon 6.2-Listen to this noise- dealer says $5k for new TX

    It looks like your on the early signs of a trans failure. You will likely get more out of it but be prepared to rebuild/replace it. No yellow metals so im guessing clutch and steels. Also the exhaust drop for the trans service is BS lmao. I hate it.

    Sudden movement when truck is parked and off

    Mine has done this since new even with the park break on if on a slight incline. I think the park paw has enough slack in it that it allows a bit off roll.

    2015 Yukon 6.2-Listen to this noise- dealer says $5k for new TX

    The pan will tell us a lot. There are a few odd clunks other than the trans it could be but im going to guess thats what it is for now. Performance rebuild is very little more for much better build than stock. TK Performance is who built mine. I give them credit for being quick and...

    2015 Yukon 6.2-Listen to this noise- dealer says $5k for new TX

    Was the trans pan dropped? Any mods, tunes, etc to the vehicle? Where was the noise pinpointed to by the tech? did he listen from under it or only when driving or operating? I ask this as noise can echo and sound like its in one area but be in a completely different area in reality.

    What brand of fluids?

    I use valvoline synthetic for the engine but thats about it. I use Mobile 1 for the trans because of the TSB and I found its cheaper by the large case. I use Delco for the rear end. I have always used valvoline on every vehicle with 0 issues. Only car I used something else on was my RX-7...

    Tune voided my Yukon warranty

    Now I am laughing my ass off. No you should not be on the hook for anything you did not cause or your tune did not cause. That would be like voiding bumper to bumper on the interior because you put katskins on the seats or you removed the 3rd row. If the modification did not or had no way to...

    Should I or shouldn't i

    Not much for it to clean out other than dilute the fuel in the tank with the high octane and bring the overall octane in the tank up. If it was a fuel ping they would quickly see a change in it after the new fuel starts circulation. Fuel additives difference is going to make no more a...

    Tune voided my Yukon warranty

    This. Is there not legislation about warranty already? They have to prove that your changes caused the failure to deny it do they not? I asking as out of curiosity. Either way I am long out of warranty. But I do have local "tuners" including one that works at the local dealer. No thanks...

    Transmission Cooler Line Leaking With Possible Fix

    Diesel is my trade specialty lol its what I work on all day every day. Those clamps are called T-bolt clamps. They apply a more even pressure around a hose and also do not dig in. Another clamp style I like for radiators and such though is power grip style clamps that shrink fit. Also if...

    Catch can fills up quickly

    PCV valve is not in the valve cover on these engines. It is under the bottom corner of the throttle body. The 2 valve cover hookups are just breathers. They do not connect to a catch can. Though you could connect a clean side separator to them.

    Did anyone go with a JEGS transmission?

    To remove and replace I am not sure as I did my own labor on mine. But the rebuild cost for my 6L80 was 3k for a 750ish HP build. The 8L90 is about 2800-3k to build for that or more HP. Also if you ship it to the builder as I did freight costs also have to be considered. I have aprox 3600...

    17 Suburban Premier - rough idle when warmed up

    The full synthetic Dexron Vi fluid. I dunno if they still have it but I got a 16qt case from summit after my trans rebuild for 92 bucks. I have thought about amsoil but I got to do more research first.

    Did anyone go with a JEGS transmission?

    I haven't but depending on your vehicle and year their instructions are off so take them with a grain of salt. I could suggest a great rebuilder but the costs will be much higher overall.
