    6L80- Drive it till it quits, rebuild local or replace with rebuilt GM part?

    I live in Aurora, Colorado. It's beautiful here. I work out of my garage and I love the summers here. No bugs. Yea it's a seriously slippery slope. I'm all in now. The dealership level diagnostics for this truck just showed up. I have a Techline SPS subscription, a GDS 2 subscription and the...

    13 yukon Denali new owner drivetrain questions

    I'd take it to a transmission shop and have them give it a health check, it's usually free. Here's the trans fluid type and the part # for a 6L80 ATF. United States Canada Application Type of Material GM Part Number US/CAN Automatic Transmission Fluid DEXRON®VI 88861037 19264717...

    6L80- Drive it till it quits, rebuild local or replace with rebuilt GM part?

    Haha.. I didn't want to explain why I have two engines for this truck, right then. Ready for the drama? The truck(yukon) broke down 11mo ago. We had only had it 4yrs and we still had a note on it.. I had it towed to a shop when it broke down on my wife; the shop that diagnosed it is where the...

    2011 Yukon Denali engine cylinder bad

    You're in good company I'm in the same boat. I replaced the engine last week and this week the trans is being rebuilt. I have a 15 Yukon and have only had it 5yrs. Do you remember that Jonnie Taylor song? 'It's cheaper to keep her' ? Get a whiskey and listen to this song.. Cheers..

    6L80- Drive it till it quits, rebuild local or replace with rebuilt GM part?

    The thought has crossed my mind more than once. When I was in the military, we rebuilt everything. I have a 8L90 on my shelf in the garage I could take apart..

    6L80- Drive it till it quits, rebuild local or replace with rebuilt GM part?

    I have a couple days to decide. Thanks for all your input, it's helping. Yea, I plan to 'hot-rod' it with a different engine and some long tube headers. I have a 415ci short block sitting on a stand. But it's current engine is just a stock L86 with an L83 cam. C

    6L80- Drive it till it quits, rebuild local or replace with rebuilt GM part?

    Yes you have it right. I'm guessing ~$800 to remove and install based on the shop hours from alldata and 100/hr shop rate. It looks like a push to me.

    6L80- Drive it till it quits, rebuild local or replace with rebuilt GM part?

    Ok, thanks for your input. Hahah.. To be candid, if this damned truck broke down once a year for the next few years I'd toss a flair in it and let it burn like I should have when the engine blew up. This thing is costing us a fortune in repairs. I digress.. To the USAA insurance adjusters...

    6L80- Drive it till it quits, rebuild local or replace with rebuilt GM part?

    This is like a Zen and the art of motorcycle maint question. I have a 15 Yukon Denali with the 6.2L, just replaced the engine with a core I rebuilt from ebay. Now that the engine is running great, it's glaringly obvious the trans is on it's last leg. Brought it to a trans shop I trust and...

    Hahah.. oh god.. Just got a call from the trans shop, it's 6L80 is shagged. I'm looking at $3-5K + These transmissions are garbage. I have an 8L90 sitting on my shelf but it's going to take an entire harness change; which I also have, to get it working. Still debating, I have a few days...

    I know right? Once I passed her the keys, we reviewed the scan pattern of the instrument panel.. Oil pressure, coolant temps, trans temp.. No noises? Check? Clear right? OK.. Full throttle.. Same as she would when she's flying jets.. lol

    Yea the DOD stuff failed and it was major carnage. Destroyed the entire engine, including the block. Worst carnage I've seen to date. The machine shop gave me back some of the broken pieces, I'm going to make my wife a necklace. I put an engine in the truck last week that I rebuilt the week...

    Yea, nice to meet you. Hehe, My wife was driving when it tore up. It left the house running and came home on a tow truck with a locked up engine and a hole in the block. However, it's all ending well. There have been 11 months of negotiations and I have talked my wife into a twin turbo's and...

    2013 GMC Yukon Denali - bad lifter?

    Yea, the DOD kit in your engine tore up.. It's tear-down time. I rebuilt and installed an engine in my yukon last week. They rebuild easy and go in just as smooth. It's not a bad job at all. It took me three 8 hr days to reinstall to completion. Book hrs are 25.7hrs for removal and reinstall...

    Transmission Replacement

    She shop should reprogram the controller, they're located on the valve body of the trans on the 6L80. If it's an 8L90 the controller is external. The 6L80 trans controller is a T43 and the 8L90 is a T87.. For the 6L80, You can use HP tuners or GM GDS2 with a Service Programming System (SPS2)...

    First post- 15 Yukon Denali w/150K catastrophic engine damage-

    Thanks for the warm welcome guys. I appreciate the back and forth. Here's some pics of the truck. This will be back to back engines. I finished up my F350's 6.0 this past spring. That was a big job. This doesn't seem to be as much work but we'll see. This engine is mechanically locked up so...

    Recommended Bi-directional Scanners? Autel?

    I use HP tuners for my 2015 Yukon. Its a steep learning curve but worth the journey. It'll do some bi directional stuff like starter relay, fuel pumps, injectors and the like. It can turn most pids on and off for the ECU and TCU.. However, it won't see other body controllers such as the...

    Hi Everyone, This looks like an active forum! If you were having a bad day, hopefully my story of woe will make you feel better about your problems. This past Tuesday the engine in my Yukon blew up, literally. I pulled the spark plug on #2 and it was flattened and difficult to get out. Upon...
