    GM 6L80 Transmission Information Thread

    Nick, I get your point about not wanting to hassle with this. I can’t find a listing for the size of the roll pins in the case for the parking pawl, Would you be able to measure one? I’d rather get a slide hammer kit with the collet style ends as I do have more uses for that sort of thing...

    GM 6L80 Transmission Information Thread

    Nick, Perhaps an odd idea but since there’s a good number of us who want to rebuild our 6L80’s but there is an investment in tooling, have you ever thought of having one or two of the mandatory tools for rental like auto parts stores. I.e. having the slide hammer for the case pins for rent for...

    GM 6L80 Transmission Information Thread

    One thing I've noticed is the wide variety of prices on converters, even one claiming "billet covers" - The big names like Yank, Circle-D, etc. seem to want about $1300 for a billet converter from their websites and they are all higher stall than stock - There are some more obvious names playing...

    LZ1 Hybrid 6.0 into Normal Truck

    Interesting, cross-reference the 2009 Yukon XL 1500 RWD as a year with a 5.3, 6.0, and 6.2 all with the 6L80 on www.fueleconomy.gov City Highway Combined 5.3L 14 20 16 6.0L 14 19 16 6.2L 12 19 15 Interesting that the 6.2L has lower mpg than the 6.0L. Kinda reinforces the desire for...

    LZ1 Hybrid 6.0 into Normal Truck

    You're hitting at one of the games I'm playing in my head about how to make this truck work the best for all the situations and not end up like my old K2500 that was great at everything but gas mileage. Is running the 6.0L on a taller rear gears (3.08s) going to do better than a 5.3L on steeper...

    LZ1 Hybrid 6.0 into Normal Truck

    Howdy folks, While there's a chance my dissatisfaction with the towing capability of my '13 Yukon XL with the 5.3L is trans related, I still can't ignore the siren's song of more power. Has anyone ever taken a LZ1 or LFA 6.0L out of a hybrid and done the AFM delete, including cam, and swapped...

    6L80E Trans Trouble

    HP Tuners work done, upload tomorrow. I have been really unhappy with shudders on downshifts and it feeling like the vehicle was ahead of the trans so I decreased the shift time on downshift from everything to 1st to 80% of original. Otherwise I followed this guide from HP Tuners:

    6L80E Trans Trouble

    Will see if I can find any contact info for him, a quick Google didn't turn anything up. Nick, just wanted to personally thank you for not only your posts on the forum in general, but following up on my thread specifically as you don't really get anything out of this with me being out of...

    6L80E Trans Trouble

    I'll poke here in B/CS though the North side of Houston is only an hour or so away. The Street Smart unit doesn't seem too far off considering a decent junkyard unit with less miles that my Yukon has in total, much less the current trans, is >$2500. Like I said, I tow a scout trailer with it...

    6L80E Trans Trouble

    I did a chat with Street Smart and a "billet converter" is the only upgrade at $150. The service network does look to be pretty forgiving but I'd rather not test that function out. Things seem to be fine for normal operation so I'll just take myself off of towing duty till I can figure this...

    6L80E Trans Trouble

    I've called around and used the online quote tool for Street Smart. Choices seem to be 1. GM reman for $6600 installed with a 3yr warrantee 2. Jasper reman for $6900 installed with a 3yr warrantee 3. Street Smart Reman for $3700 installed with a 5yr parts warrantee but $50/hr labor rate 4...

    6L80E Trans Trouble

    It may be hotter than I'd like but I can concede that it might just be the way things are now and with the 10ºF bias on the readback it could be OK. What I'm struggling with is the slipping and banging into 1st that came with the higher temps. If I drove this vehicle around town as my daily...

    6L80E Trans Trouble

    Thanks to all the responses. I did read the entire (well skipped the argument part) 6L80E info thread last night and was able to cross some of my symptoms to it and did some checking this morning. I made it home safely with no issues on the way but that doesn't mean I trust it... Luckily, I...

    6L80E Trans Trouble

    My apologies for any duplication but am on my phone, away from home so searching is pretty hard. The 6L80E in my 13 Yukon XL RWD is acting up and I'm debating trying to slap together so thing to make it back home or just run it. The truck doesn't have the HD cooling package so I only have the...

    2013 Tahoe passenger side door handle cracked

    I just did my door pulls today with 3M Windoweld. The drivers side still had basically all its plastic inside just with single break in it so I just worked around it and filled the handle up. The passengers side had basically no intact plastic so I put a 1/4in Al rod through it and filled it...

    A different approach to repairing the dreaded door pull

    How's this holding up? Interested to see how the JB weld replacement for the essentially plastic rivets that were there originally are holding up. Thanks

    2013 Tahoe passenger side door handle cracked

    Follow up since this is pretty much irreversibly, how's it holding up? I'm guessing you just peal up as much of the vinyl covering as possible to get the steel rod in there as a reinforcement before squirting it full? Thanks

    Manual Mirror Tip

    Too bad there isn't three settings on the memory. I could do it but the wife would get bumped for the feature and I think I prioritize her over the tilt.

    Manual Mirror Tip

    Howdy, Is there a way to manually trigger the mirror tip like you can setup for triggering in reverse? I like the tip for backing into parking spots but not for backing out of my driveway. Any way I can just get it when I want it, maybe set the seat memory for the seats in the same position...

    Stripped Seat Height Adjuster Gears

    Howdy, So I've been doing some digging into how to address the most pressing bits of my new to me 2013 Yukon XL and doing some more digging into the seat adjuster failure, it looks like GM has taken a page from the old Ford power window motors with plastic gears that eat themselves. There is...

    Migration up from GMT400

    I can hear the motor turning and it's running faster than the front adjuster even unloaded so I can only assume the block has stripped out and the screw is just spinning inside.

    Escalade Front Seats in SLT Yukon

    Howdy, So the drivers front seat of my '13 Yukon XL SLT has a broken rear leadscrew so the back won't go up and down. It also has a small tear that I can patch up so that's less of an issue. I have found a set of seats out of an '09 Escalade that are fully functional and in mostly better...

    Migration up from GMT400

    204k miles on the Vortec 454. It is a vandalism recovery rebuilt title though. Was perfect for someone with a tight budget and good mechanical skills and time but now I'm on a less tight budget but without the time to keep after it's 25yr old needs. The main issue that really makes it get...

    Migration up from GMT400

    Howdy, I must migrated up from GMT400, both in terms of the forum and vehicle. We've had a 1998 K2500 Suburban since 2015 but it's maintenance was growing both beyond my own skills and my time to invest having gone back to grad school for a PhD in Nuclear Engineering in my 40's. We just got a...
