What are everybody’s thoughts about there new transmissions in their truck?

 

I have the new 10 Speed mated to the 6.2.

 

I have had a couple loud clunky downshifts.  One was today with about 1150 miles.

 

mostly it has been very smooth though.  I hope it doesn’t get worse.

The 8L90e is a nice trans when it works. My K2 SLT is on its second one at 20,000 miles. I don't think the problems GM have is the trans itself, but the hardware/software controlling it. Sounds like they still have some learning disabilities in this regard for the T1 trucks. That's unfortunate, I may have to finally try another brand.

I have the 8 speed 5.3. I’ve had a handful of downshift clunks too. Otherwise it’s been pretty smooth. I’m going to check tomorrow to see if there is a tranny flash available.

I have the 6.2 10 speed. Overall really satisfied with it. Most of the time you can barely notice when it’s shifting. Very smooth overall.  I’ve only noticed it downshift kinda loud a couple of times and I’ve got close to 900 miles.

The 10 speed clunkiness could have something to do with the Dynamic Skip Fire tech and synchronization between this new fuel saving feature and the transmission itself.

Much like some of the clunkiness with our K2 6 and 8 speeds and the AFM working with them.

My 08 Sierra clunked my 14 clunked and my 16 clunks as well. Just something I got used too. Gm Precision ?

Overall the 10 speed is much better than my 2015 8 speed (BY A LARGE MARGIN!) and the two 6 speeds in my 2017 and 2016; I feel like this transmission has the ability to be very good.  In fact, it could be excellent after some miles.  But there are the occasional clunky feeling downshifts.  I did have one downshift clunk with this 10 speed this week that I thought, damn, that was hard.  Has only happened once though.

My last truck was a 6 speed and the 10 speed is night and day different. So much smoother. I really started to hate my 6 speed on how jerky it was in between gears. I like a nice smooth ride. I think I can live with a few clunky downshifts here and there. I think this is going to be a great truck overall. Not being biased :rolleyes: but I think the new Silverado is one of the smoothest riding vehicles out there for the $$$ . It drives just as smooth as our Volvo XC90. My buddy just bought a new Escalade and he thought my truck drove better. He was envious of the smooth ride and the power of the 6.2. haha :)

IF I were and Escalade owner....  aside from ride and power envy...….  I would be most envious of the Cost savings with the Silverado! 

Escalades have been and always will be an overpriced status symbol!

Any of you guys tried to downshift manually on your trucks with the 10 speed? How does it feel? Clunky?

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
