    2017 Tahoe Trans rebuild advice?

    OK..... Then without quoting prices, how many 6L80s have you rebuilt? And how many hours does it take to rebuilt one? And what is your warranty? Do you dyno those trannys before you deliver? Always a huge risk buying from a small indy who doesn't R&R because it doesn't really have to work...

    2017 Tahoe Trans rebuild advice?

    OK.....welcome the push back. I didn't say all shops, I said very few. And that's because rebuilding a 6,8 or 10 speed transmission IS a very specialized skill. And I KNOW that NOBODY on this site is pushing > 800hp with an L86 engine because the direct injection fuel system of the LT1/L86...

    Here's a weird AC issue

    15 Escalade. So my front AC won't blow cold unless I turn the rear AC on then its fine. Weird huh? Gotta be a switch or a sensor somewhere but I'm not an AC guy so have no idea. Any thoughts?

    2017 Tahoe Trans rebuild advice?

    That looks cool. Any documented references on that conversion. Everybody makes YouTube videos on successful swaps, right?. Any links for show and tell. And their kit is $3K? So I need a 10speed trans and the kit?

    2017 Tahoe Trans rebuild advice?

    Very few that I would trust. Why take the risk when you can buy a new one from GM for $3400? with a warranty. Seems like an easy decision to me. But if you need a performance 6L80 these guys are the best. Always in Texas...LOL And they tell you what you get. For stock engine, this build is...

    Need Advice - 2018 Yukon Denali - needs new engine

    Bro, where do you live? Are there no good private shops around? So your status is currently with some unknown dealer at $16K down from $22K? Thats closer. I would park it at your house and shop from there. The price of a new GM 6.2 engine is not going to change. 10K for crate, 7K for long block...

    2017 Tahoe Trans rebuild advice?

    Geez...... 17 Tahoe is 6l80e. New from GM is ......$3800? approx 2WD or 4WD I wouldn't let private shop rebuild my 6l80e, it's a very specialized skill. Very. Watch precisions transmissions on YouTube. Here is a GM dealership that sells em online. R&R a tranny is easy. 3 hours max...

    Need Advice - 2018 Yukon Denali - needs new engine

    LOL 22K? LT4 Conversion? 18 Denali is 6.2 L86. Complete crate from GM is $7500 retail + R&R at Dealer is $3K-4K....so 10-11.5K....22K? Major mark up. And that will have DOD....more LOL. I like the guys in Washington, rebuilt 6.2 no DOD......$6100 but you need to find a shop to install...

    DOD / AFM delete parts

    It depends what you feel comfortable with....I guess. I just wouldn't put a new cam in a 240K engine. And I don't pull the trans to replace the engine. I just unbolt it from the Tq converter and the trans, Engine mounts, coolant hoses, harness connections.....and pull! It's just a big heavy...

    DOD / AFM delete parts

    Congrats getting to 240K! Original Trans? Your tic is probably not an AFM thing, maybe just normal wear and tear on a 240K engine. LOL. I would not do major surgery (which DOD delete is) to a 240K engine. It's basically the labor associated with heads and cam. You may want to consider a crate...

    P0340 and P0341

    1 camshaft sensor. That code can be a few things. Camshaft sensor, wire connectors to the sensor, broken wire in the main harness, or even a bad circuit in the computer or aftermarket cam of course. Is it behaving funny at all? taking longer to start? poor fuel mileage, etc? A good mech will...

    Buying a 2020 Yukon with L83 5.3L EcoTec - Should I worry about AFM Lifter Failure

    My 2 cents. DOD is great in concept but in application has high probability of failure. I know a shop where HALF of their work is DOD delete on LS and LT engines, $4100. They love it. Without DOD, the 5.3's and 6.2's are great! My 6.2 made it to 90K and I "tuned" out DOD at 50K. I would not buy...

    AFM lifter fail on my 2018 Yukon Denali

    Cool. That is the one they actually sell with the kit. I'll get that one too. Thanks again!

    AFM lifter fail on my 2018 Yukon Denali

    Thanks for the update. I want to try that cam. The Lower lift and bigger fuel lobe must be giving you more lower end TQ, which is translating into increased responsiveness with less throttle, thereby also the better fuel mileage. I have all my parts now except for the cam but I can't find that...

    AFM lifter fail on my 2018 Yukon Denali

    Good walkthrough! Thanks! How many hours did that take you, in work? 30-40? And you didn't change the tune for that cam? Just DOD "tuned" off? I am procrastinating on mine. I have decent ticking on the driver's side, and has for about 10K miles. Ticking like a time bomb. LOL. Thanks again.....I...

    Scored lifters and camshaift replacement

    That sounds about right for cam and lifter replacement at a dealer. It's a lot of work and the worst part is, it won't fix the problem. You'll still have a DOD engine and it will fail again. What you should do if you want it to last, is find a shop that will put it back together with a DOD...

    6.6 Gas L8T Engine Swap in 2015 Suburban

    They are doing it. Mast and TSP offer the L8T with port injection options. Mast has one with a charger on it and 1000+ hp. All you need is 58x reluctor computer and a gen v intake with injector provisions. I think the tuning would be easier on the port injection. Don't know about the front...

    6.6 Gas L8T Engine Swap in 2015 Suburban

    Cool swap! I've been looking at same with my 2016 Escalade as its starting to tick a little louder than I would like, even with DOD "tuned" off. GM sells a 6.6L long block and it should drop right in as the external points are all the same, even intake and exhaust. The work is the tune and...

    Considering 2015-2018 Denali, best transmission?

    I have a 2019 Sub 6.2 10spd and its a great tow vehicle! Tows almost as good as my Ram 2500 Cummins but handles better. With an 8000lb load gets about 10-12mpg and has no problem with hills or trans temps in 110 degree heat in AZ....where the speed limit is 75mph with a trailer. I also recently...

    I'm about to buy a 2018 Tahoe Premier, please give me your insight!

    Premier is good, Premier with 6.2 is better.....2018 5.3 for 40K seems kinda high, but that's been normal. Here in CA I'm seeing SUV prices (along with RE) crashing with rising rates, recession looming and gas sticking at $5.50 a gallon. I just got an 2015 Escalade 2WD, 70K miles for $30K...

    Arnott sk3354 vs. Acdelco o.e. ride quality?

    I am still undecided. To me, the price just seems kinda high for a non adjustable strut with a baked in magride simulator. I bought some sims off amazon so I'll plug those in and if they work, I'll select some shocks. The Bilstein 6112 kit is $800 and has 2.5" body and adjustable height. I have...

    Arnott sk3354 vs. Acdelco o.e. ride quality?

    I'm leaning towards the Arnotts. They say lifetime warranty and built-in computer bypass. Computer bypass is the key. Otherwise I'd go Fox or Rancho. I read they are designed by Arnott but built by Eibach. And if they are good enough for Thrust with the supercharger and big brakes they are worth...

    Arnott sk3354 vs. Acdelco o.e. ride quality?

    I think it depends on the ride that you like. I like firm. I have a 15 Escalade and previous owner had already installed NER magneride knockoffs. I like firm but below 65mph they are way too stiff. Above 65 they ride great! In reading the posts it sounds like Arnotts have a softer ride. I'm...

    2500 Overheating when towing

    I'll watch to see how you get the cooling temps down. I kinda have the same problem with towing larger loads, 6000lbs+, with my 03 Tahoe. It has a built 6.0L and trans and powertrain is not a problem. I'm so impressed by it towing capability. But this week it was 110+ degrees in AZ and the stop...
