Have to remember there is no 10 speed 2wd trans option yet, which is why the 6.2 is still limited to the 4wd models. 

Really? I didn't know that. I know it's the same as the Ford 10 spd except for the valve body. Unless they are trying to get folks to spend that extra 4-5k.

And this is why you avoid the first model on a update.. lol

Funny you had mentioned that. I put a lot of consideration when I was buying this truck but then I remembered my 99 Silverado. First year with 5.3 and drove that thing till the bed rusted away. Then my parents 07 Tahoe 300k miles on the thing when they sold it. Point is either gm made better product back then or we might have a chance with these trucks to last and be reliable.

In another post it explained that the 8-speed for the new T1 trucks has a new RPO code, meaning it's not the same one used in the K2s.  Same for the 10-speed if memory serves.  Different enough anyway.

 

Long live the 6L80/6L90 though!

The 8 speed got a new torque converter design for the 2019's and up I believe. Perhaps the new torque converter can be used for the previous 8 speed? I also haven't really heard of people complaining of the 8 speeds in the Canyon/Colorado, though I don't see why it would be exempt from the same shifting characteristics. 10 speed is all new for GM and Ford, I haven't really heard anything negative on it as of yet (except from haters of one brand to the others involvement). The one truck I drove with it was really smooth and would downshift instantly when I wanted the power, unlike my 6l80.

My 6L80 has been tuned and grabs the right gear without lagging as it did before the tune.  That's been my favorite part of the BlackBear tune; what Justin did for transmission performance.

Why keep the 6 speed though? I know it's only paired with the 4.3 V6 but one would think it might give them a leg up against fleet competitors as it should improve towing by a little bit. Offering the 10 speed at lower trims with the 5.3 is a good move except for the must select 4x4 part. Also glad to see the 6.2 going to lower trims finally. Guess it took Ram knocking them down to third place to wake up and become competitive lol

 

6 speed is used on the L82 5.3 as well for WT/Custom/Custom TB.  Cost.  6L80 has probably paid for itself by now, and it helps keep cost of entry lower.  The 8 may trickle down, or just get replaced all together at some point with the 10 speed.  Also, the 6L80 was re-tuned for T1 and is better than in K2.

Correct.  The big change was adding the CPVA torque converter like the 2.8 Duramax got to absorb unwanted powertrain vibrations.  DFM's lack of feeling can be attributed to the converter.

I remember people ragging the 700R4. I’ve had it behind two high performance vehicles. One a 454, my current 92 Chevy truck. It’s had a blower since new. Given some time the kinks get worked out.

I remember. I was one of those people having replaced on in the wife's Caprice several times. The I found a performance builder than knew more than replace broken parts and WOW!! That's a nice gear box when well sorted. I expect most of them will be given some time. :thumbs:

Are you sure because you can get a ford f150 2wd with a 10 speed. I would think GM would have one also.

My 19LT Trailboss build date is 6/17. This just makes me want to try to cancel and order a 2020 with the 6.2 and 10Speed. F**K

      Injector update

      By iso221 · Posted

      Because single shot injectors are ancient and multi hole injectors provide smoother running engines and sharper throttle response due to the fuel being atomized better..the best lead I have is a 24lb blue top injector almost everything matches up but the injector will put out about 26lb/hr which is just outside the gm threshold.figured id ask here to see if there was an absolute answer

      Injector update

      By CamGTP · Posted

      Why is my question?   Any change in injectors requires a tune. Unless you are going back with the OEM part number or a newer part number of that same injector.   Any size difference or type difference like the EV6 style injectors all have different injector data for them. And there is no EV6 injector that matches the factory 25 lb/hr size that your truck comes with. I've been messing with these trucks and tuning them for a long time and what you trying to do doesn't exactly make sense to me.

      When a condition becomes a business model.    https://www.gm-trucks.com/gm-truck-suv-incentives-pricing-2026/   Zane posted this in "Latest Articles".    The honest bottom line   Truck buyers have spent three years assuming this is a temporary condition that will break once inventories normalize. GM just presented it to investors as a durable strategy, on a chart, as evidence of good management.   Inventory did normalize. GM is at 511,000 units and squarely inside its own 50 to 60 day target. The discounts still did not come back, because the low incentive number is the goal rather than a symptom of shortage.   Plan your purchase around that reality instead of waiting for it to change. Follow our ongoing GM News coverage for pricing and incentive changes as the next-generation trucks land.

      Winter Returned

      By Grumpy Bear · Posted

      Thought it was raining this morning when we woke. Nope. Dew point was over 80 F and humidity 98%. Zero visibility distance. Everything was 'sweating'. I've seen rain come out of clouds but never out of Pepper or the tree trunks.    Wicked storms just missed us sliding off to the east but by blocks. Heat index about 110 F with air temp in the 90's.    This is  our third wave this month of multiple days of this type of weather. And yet the grass is going dormant and the ground is cracking this side of the street and water up the the hood opposite. Just weird stuff going on.
